Patek Philippe, the world’s top brands in the top five super talent shows itself brand, is the most recognized worldwide world first brand watches, 175 years of glorious history tab, any watch any region in the world rankings, even a variety of top ranked list of trade-offs, but Patek Philippe has always ranked first.
Whether it is technology, technology, design and development capabilities, it can be said that Patek Philippe is the watch industry leader, is always ahead of the pace of the times, with more stringent standards tab, and in most factories are difficult to reach the ultimate complex field, Patek Philippe is more handy, under various “table” products emerge in an endless stream that is almost every year to refresh their records.
Richard Miller Picasso or Ferrari, Patek Philippe is Da Vinci or benz. They all belong to one group and do not fuse with each other. Famous brand products generally have a common characteristic that is the accumulation of time, Patek Philippe profound historical and cultural heritage is not a new product can be replaced in a short time.
Patek Philippe has been doing market work for many years and continues to be welcomed by the market and will continue to grow organically, including watchmaking and selling prices. Coupled with perfect after-sales service, high heat secondary market performance, enough collection crowd, etc., together to form a brand in the market king position.
Although Mitchard Miller is very good, and has taken a different road, is very hot, popular, and the secondary market performance is getting better and better, but there is still a long way to go from “replacement”. Not absolutely impossible, but definitely not so easy.
The luminous watch can still read the time without difficulty in the night. It is not only convenient, but also very magical.
The reason for this is that luminous watches are often painted with luminous material on pointers and time scales. At present, the most popular type of luminous material used in advanced watches is SuperlumiNova, which has no radiation and can emit light for a long time.
This material belongs to the light storage type, generally speaking, the material itself does not light, but through the light, until the “eat” light, will show its mettle, bring clear display in the dark place. As a result, some brands use lights to show their watches in order to show their luminous effects.
There is, of course, a self luminous, that is, without the external light, itself will shine. For example, Ball and other brands, the use of a self luminous micro gas lamp, equivalent to in the pointer, when the standard place a small light bulb, and sometimes colorful, very beautiful.
If you need to purchase a luminous watch, in the end the brand has Ball mentioned before, the high-end brand, Blancpain fifty fathoms, Rolex, Panerai etc. are good. Rolex is now using luminous, usually Chromalight, a unique blue light at night than the above mentioned SuperlumiNova brighter, and Panerai can be said to be the first to do luminous watch brand, regardless of appearance or luminous, are very awesome.
Fundamentally, the biggest difference between quartz watches and mechanical watches is that they drive different sources of power. Quartz watch is issued by the battery power to “stimulate” quartz crystal form, of which the law of vibration driven by the hour and minute hand operation, because the vibration of quartz is very regular, so when the quartz watch will be much more accurate than mechanical watches, one day the error will not exceed a second rate.
Manual chain mechanical table to be tightened by rotating the hairspring crown gear drive operation, then the balance rotating through gossamer natural relaxation, and drive other components to rotate, so as to achieve the purpose of running watch. Automatic timepiece is coupled with a weight balance, when the hand motion is able to watch the movement chain, which led to a series of gear transmission.
Mechanical watches can be divided into two kinds of manual and automatic:
Powered mechanical watch movement depend on remontoir, do not need batteries.
Mechanical travel time and quartz watch, mechanical watch is the second uninterrupted walk.
Because the mechanical watch movement is complex, the travel time error depends on each brand.
Fine workmanship, easy to use, the upper winding, more than 36 hours can walk. Long movement life.
The appearance is heavier than the quartz watch, and some brands are thin, but they are usually manual mechanical watches.
Quartz watches can be divided into digital, pointer and automatic watch and optical kinetic watches:
The quartz watch is very accurate.
The movement adopts the integrated circuit, the structure is much simpler than the mechanical watch movement, and the assembly is very convenient.
Easy to use, do not need to wind up, a battery generally available for 2-3 years. But some quartz watches with lithium batteries, long service life, can be used for about 7-8 years.
Quartz watches are cheaper than mechanical watches.
Many people think that quartz electronic watch life is too short, not durable. In fact, this view is wrong. A good mechanical watch can be used for about 20 years, but this time every three years or so will need to refuel time. As the mechanical parts of the wear and tear, often to repair or replacement, travel time error will increase.
What is the life expectancy of the quartz watch?
General quartz watch short-term life of 5 years or so, and long-term life of up to 10-15 years or so. Watch the life of the watch and the maintenance of the specific circumstances of the watch are closely related, if the watch use and maintenance methods are correct, you can greatly increase the life of the watch. Short term life refers to the battery running out of power, coil parts short circuit and open circuit, quartz oscillator leakage, CMOS integrated circuit damage. Replaceable parts are resolved without affecting long life.
How long is the life expectancy of quartz?
Quartz electronic components can be said to be semi-permanent, in addition to every 3 years or so to change the battery, the service life is much longer than the mechanical watch, so life is relatively long, do not worry in a short time Inside the watch on the broken issue.
Panerai is an Italian watch company founded in 1860 by Giovanni Panerai in Florence, Italy. It belongs to the Richemont Group since 1997. The brand is in Neuchâtel in Switzerland.
Military and maritime Panerai inspirations , the brand that is present since 1860 has participated in major events such as the First World War, being the official supplier of the Italian Navy.
Panerai Watches are today still a myth in watchmaking. The watch brand Panerai, initially only known collectors, became in a few years, a star of the watch market. His greatest admirers gathered under the name Paneristi.
Finding inspiration in his historic mastery of instruments dedicated to navigation or the measurement of the time under the sea, Panerai has been able to position themselves in manly’s luxury, essentially nautical sports sector. Its products have an unquestionable identity and have this unique quality of gather around a Swiss the best technical expertise of Italian design.
Dear , we have same type, the price is lower a lot, please contact our customer service, you will have a pleasant surprise
Dear watch fans, do you know the meaning of water resistance dive bezels, depth gauges？
How water resistant should a dive watch be?
Some manufacturers say that their watches with a water-resistance rating of 300 meters or more are suitable for recreational scuba diving. Others say the watch need have a rating of just 200 meters; still others say it can be 200 meters as long as it is specifically labeled as a dive watch. The International Standards Organization (ISO), on the other hand, stipulates that a dive watch must be water resistant to 100 meters.
All these depth ratings are significantly higher (or lower, if you will) than the depths to which a non-professional diver can dive. Recreational divers don’t go deeper than 40 meters (130 feet). Beyond that, they enter the realm of technical diving, which requires extensive training, special mixed gases to breathe, long decompression stops and special equipment.
The reason for the discrepancy: when tested for water resistance in the factory, the watch is in an artificial environment that is much different from what the watch will face during an actual dive. For the test, the watch is perfectly stationary, the gaskets brand new, and the case newly assembled, so that nothing will compromise its water resistance. The testing machinery does not account for such phenomena as additional pressure from the impact of the wearer’s jumping or diving into the water; or for temperature and pressure changes as the diver ascends and descends, which can cause the case to shrink or expand. Furthermore, a watch’s water resistance will be lessened by aging of the watch’s gaskets. Knocks and other rough treatment can cause the case’s components to fit together less tightly than they did when the watch was brand new. All these imponderables cause the companies to provide a rather large cushion of safety so that customers will not hold them responsible if their watches leak.
What features make a watch impermeable enough for diving?
Several features are required to make a watch impermeable enough to wear diving. In nearly all dive watches, the case has a screw-in back and crown. O-rings are used to seal the crown, caseback and crystal. The case and crystal are thicker than in a non-dive watch. Watches designed for very deep diving often have additional pressure-defying features such as domed crystals, or a steel ring for reinforcing the case (as on the Rolex Deepsea).
What are the other features of a dive watch?
Most dive watches have a rotating bezel for measuring elapsed time. They also have luminous hands and markers that can be read underwater. ISO standard 6425 requires a dive watch to have a “time-preselecting device” (a rotating bezel satisfies this requirement) and a dial that can be read in the dark at a distance of 25 cm. The ISO also says the watch must have an indicator that shows at a glance if the watch is still running. A seconds hand satisfies this requirement. Most dive watches have a steel or titanium bracelet or rubber strap, although some straps are made of nylon or various composite materials. Some dive bracelets and straps are equipped with an extension device that enables the watch to fit over a dive-suit sleeve. Some dive watches have a helium valve and/or a depth sensor.
What is a helium valve?
A device for equalizing the pressure inside and outside the watch case when the watch is worn in a diving chamber. Inside the chamber, divers breathe a gas mixture that contains helium. The helium molecules are extremely small and are hence able to penetrate the watch case, building up inside it. In the process of decompression, the pressure inside the chamber decreases more rapidly than the pressure inside the case. This can cause the watch crystal to pop off. To prevent that, some watches have a valve on the side of the case that allows helium to escape from the case during decompression, making the pressure inside and outside the case the same.
Do many dive watches have helium valves?
Most dive watches do not have helium valves because they are of use only in saturation diving, when a diver spends time in a diving chamber.
Why do the rotating bezels on most dive watches turn in only one direction?
Most dive bezels turn in one direction only, counterclockwise, so that the bezel cannot be accidentally knocked off position in the clockwise direction and thus understate the elapsed time (usually the total dive time) being measured. Some watches solve this problem by using inner rotating bezels that cannot be rotated accidentally.
Many bezels have only the first 15 minutes marked individually. Why?
This is a dive-watch convention that goes back to the mid-1950s (it probably started with the Rolex Submariner). It is unclear what purpose the markers were originally meant to serve. An early Submariner advertisement shows a diver setting the bezel to measure total dive time, then using the minutes markers for a precise reading of his descent time. Why this information is useful is not explained (and standard diving procedures don’t require it).
An oft-tendered explanation for the markers is that they are used to time decompression stops, but this explanation is problematic. The diver would have to reset the bezel at the beginning of each stop. The bezel could not therefore be used to measure total dive time, the main purpose of the bezel.
One possible explanation for the markers: 15 minutes is the approximate amount of time a diver can spend at 130 feet, the maximum depth for recreational diving, without making decompression stops. The markers might have been intended to alert him to that limit and help him read his remaining bottom time precisely. This theory is supported by some versions of the Omega Seamaster, which had gradations for the first 20 minutes (a diver can spend about 20 minutes at 110 feet, close to the depth limit). On the Seamaster 200, the 20-minute segment was painted fire-engine red, possibly to warn the diver of the hazard of staying deep for too long.
How do depth-gauge watches work?
In most, there is a sensor (typically a membrane or diaphragm) on the side of the case that is distorted by water pressure. The degree of distortion is then converted into feet or meters of depth and displayed by hands on the watch face. Oris, in its Aquis model, uses another type of depth gauge: it has a tubule around the perimeter of the crystal with a tiny opening to the outside. More or less water enters the tubule, depending on the depth, and the diver can read the depth in meters on the scale next to the tubule.
How many mechanical dive watches have depth gauges?
Just a handful. Aside from the aforementioned Oris Aquis Depth Gauge, other mechanical watches with depth gauges include the Blancpain X Fathoms, the IWC Aquatimer Deep Three, the Jaeger-LeCoultre Master Compressor Diving Pro Geographic and the Panerai Luminor 1950 Pangaea Depth Gauge (which despite its mechanical movement has an electronic depth gauge).
Some watch depth gauges record the deepest point of a dive. Why?
There are three reasons. First, for safety’s sake, the dive-time limits prescribed by dive tables assume the diver spends his entire dive time at the deepest point of the dive. To use the dive table, the diver must therefore know his deepest point. Second, it is a generally accepted rule of diving that the diver should do the deepest part of the dive first. This gives him the maximum amount of time to off-gas the relatively high amount of nitrogen he absorbed at the bottom of the dive (the lower you go, the more nitrogen dissolves in your blood). Third, many diving experts recommend that, even in no-decompression diving, which doesn’t require decompression stops, the diver make a so-called “safety” stop of one minute halfway between the lowest point of the dive and the surface in order to off-gas nitrogen.
Which mechanical watch has the deepest water-resistance rating?
The CX Swiss Military 20,000 feet. The watch, made of titanium, is nearly 3 cm thick; the crystal alone is 1 cm thick.
In this age of dive computers, are dive watches necessary?
Not really. Divers sometimes take them as backups to their dive computers, should the computers run out of power during a dive, but now that wrist-worn dive computers are widely available and reasonably priced, some divers use these as backups to their console-style computers (or wear two wristwatch-style computers). If a diver does use a watch as a backup, he also needs other backup equipment that supplies information given by a dive computer: a depth gauge, pressure gauge and dive tables.
Then why do so many people buy dive watches?
For several reasons. Many people like the sense of security that a high water-resistance rating provides. If a watch is safe to wear on a deep dive, they reason, surely it is guaranteed to survive a swim or a snorkeling excursion. Others like a dive watch’s other features, such as a rotating bezel or highly luminous hands and markers. For many dive-watch wearers, looks are the main draw: sporty, technical-looking watches are all the rage.

Rolex Sky-Dweller Rolesor Watches For 2017
Among this year’s new releases for Baselworld 2017, Rolex is introducing some tweaks to the Rolex Sky-Dweller watch with “Rolesor” model options. While an all-steel version is still frustratingly unavailable, these two-tone gold and steel models represent a relatively more budget option. It’s a step in the right direction, at least. As even the slightest stir from Rolex is apparently headline-worthy, let’s take the loupe to this 2017 Rolex Sky-Dweller, beginning with the new hands and indexes.
These new Rolex Sky-Dweller models are characterized by the blocky, rectangular indexes and longer hands. Previous models have all been Roman or Arabic numerals that could even be viewed as quirky in a Rolex context, so this adds a significantly more standard and conservative option to the collection. Further, it will allow Rolex savants to distinguish at a glance, say, an all-white-gold model from a two-tone steel and white gold model. Longer hands, as we saw on the Rolex Explorer last year, are always a welcome improvement to legibility and aesthetic balance.
Between a few dial color options, these features debut on a range of about six Rolex Sky-Dweller models, with two variations of a “Rolesor” case. If you’ve been living under a rock (or have a life outside of watches), “Rolesor” is Rolex’s special term for a two-tone case, meaning steel and gold. In this release, we are talking about steel plus yellow gold or white gold. Owners, at least, of two-tone steel and white gold models will hopefully know which parts of their expensive Rolex Sky-Dweller watches are which material.
The new hands and indexes also give a lot more surface for lume (or “Chromalight”) than previous Rolex Sky-Dwellers, and Rolex is emphasizing just how glowy they will be in the dark. Other features of the Rolex Sky-Dweller are mostly carried over from past versions. That includes the cool and useful Ring Command bezel that rotates to different positions and is used in conjunction with the crown to set the various functions that include a 24-hour second time zone and annual calendar. The 42mm case is water-resistance is 100m. The new Rolex Sky-Dweller models come on two-tone, solid link bracelets with Rolex’s handy Easylink extension system that many will be familiar with.
The Rolex caliber 9001 inside with its antimagnetic Parachrom balance spring and Paraflex shock absorbers is, of course, certified by Rolex’s own stringent tests and guaranteed to be accurate to -2/+2 seconds per day. This is standard across all Rolex watches but still impressive, and you canread more about Rolex’s certification standards here. The 9001 has automatic winding, of course, and gets a power reserve of about 72 hours. The ability to set the functions backward or forward safely is an appreciated feature, and you have to love the clever way of indicating the month – in red, through an aperture on the periphery of the 12 indexes.
These new Rolex Sky-Dweller models will only broaden the collection’s appeal both thanks to their sensible design and more accessible price. The Rolex Sky-Dweller is Rolex’s “other” GMT watch that is aimed at the gentleman traveler more than the sporty traveler’s Rolex GMT Master watches.

There’s an embarrassment of excellent new divers coming to market right now, and IWC have jumped right in and announced the addition of three new additions to its well regarded diver’s watch family. One of these is the Aquatimer Automatic 2000(Ref. IW358001), so called because it is water resistant to 2000 meters.
IWC’s Aquatimer Automatic 2000 for 2016 comes with yellow hands and numerals and a black dial. The origins of this timepiece go all the way back to 1982 with a watch designed by Ferdinand A. Porsche for mine clearance divers. The Aquatimer Automatic 2000 is intended for the ambitious amateur and professional divers alike.
It’s powered by an IWC-manufactured 80110-caliber movement with automatic winding and a 44-hour power reserve. Like other watches in the IWC portfolio the watch features a mechanical external/internal rotating bezel, the SafeDive system and luminescent elements. The movement is housed in a 46mm titanium case. The engraving of a deep-sea diver on the case back and the black rubber strap complete the sporty appeal of the watch.
