The chemical composition of synthetic green sapphire includes copper and aluminum oxide, with the copper being the element that is ultimately responsible for its signature green hue. The process of synthetic sapphire production is an expensive and exacting one; however, the additional obstacles that accompany the addition of copper – and the precision required to achieve the right amount of green tint without compromising the strength or clarity of the crystal are likely responsible for its exclusive use on the Rolex Milgauss line of watches.When synthetic sapphire is manufactured, the material has to “grow” over the course of a period of several weeks. Particles attract to one another, forming layers that fuse together to create a dense and ultra-hard substance. The end result of production is a “boule” – a solid piece of synthetic sapphire shaped like a chunky cylinder, which is then cut and shaped to its necessary dimensions.Due to the high costs of production, most watch crystal manufacturers cut their synthetic sapphire boules in a perpendicular fashion, as to maximize the number of crystals that can be created from a single boule. Although this is entirely unconfirmed, it is rumored that Rolex cuts the boule along a diagonal axis to maximize the clarity and strength of the finished crystal. In addition to complicating the cutting and shaping process itself, cutting the boule along a diagonal axis significantly increases the amount of waste, which further adds cost to an already expensive manufacturing process.Despite not making an appearance until just over ten years ago, the green sapphire crystal has quickly become one of the defining characteristics of the Milgauss line. Its pale green tint possesses no functional advantages over a traditional, clear/uncolored synthetic sapphire crystal; however, the green crystal that is exclusively fitted to the Rolex Milgauss 116400GV is one of the primary reasons that individuals seek out this particular reference. The green crystal is something entirely unique to the Milgauss collection and is not something that is found on any other Rolex watch, past or present.
The case of this replica was made of solid 316 stainless steel. In order to be more harmonious as a whole, there are several key components have used this material. Such as its bracelet, has been polished based on stainless steel. And its crown, even its Arabic numeral markers and bar markers in the while dial. All of them are in concert with its main tone. The markers and hands have been coated by super luminous with different colors. Blue color was used in hour markers and hour hand. Green color was used in bezel and minute hand. Such considerate design can guarantee that you can read time clearly no matter in day or at night, and when diving in dark deep sea. You still can distinguish time information in shorter time. The date display window was set in the place of three o’clock. Considering of ocean such specific environment, this Omega Planet Ocean replica used superior quality to ensue practical function. Such as its bezel, except its unique character that was different from anther diving wrist watch which surrounding with numerals in bezel for chronograph. Its bezel inlaid diamond just with the motivation that showing the glamour of diamond and the craft of inlaying. In addition, it used white ceramic which can be tough enough to adjust the environment of deep sea.
Today there is quite a high premium on original vintage pieces simply because they’re extremely rare and becoming increasingly harder to find. Decades ago, when people bought luxury watches like Rolex for example, it was perfectly normal for them to get the watch serviced, polished, or have parts replaced if you scratched or dented them up. The problem is that while they were done by the company with authentic later-era parts, they still weren’t original parts or features of the watch. Since this was such a common practice, today it’s really special – and highly valuable – if a vintage watch is totally original.When posed with the question of which watch to buy and when, every industry “expert” probably begins their answer with some variation of the same caveat: Buy for love, not for money. Watch collecting is a wild and unpredictable hobby. Auction prices for classic models have been known to hit eight figures (and then some), but most of the Rolex watches out there depreciate the moment you strap them on your wrist.I have a young friend who is ready to buy his first luxury watch. He’s been thinking about it for weeks (good boy), but every few days he calls me (bad boy) and labors the same point: He wants a watch that is an investment (even worse boy). There exists in modern watch collecting a problem: collectibility is now treated as a selling point. But the problem with everybody and their dogs knowing that something is collectible is that everybody and their dogs are quite likely to collect it.The most expensive wristwatch ever sold was the Rolex Daytona worn by Paul Newman himself. It fetched $17. million at a 2017 auction. That’s a pretty good price for a watch that was so unpopular when it was initially launched that it lingered on dealers’ shelves with relatively few actually making their way onto customers’ wrists. One of those wrists happened to be Paul Newman, who had reputedly been bought the watch by his wife, Joanne Woodward. And it isn’t that she made a sound investment, but rather her purchase created an investment piece by her gifting it to her stratospherically famous husband.
About the movement, ZF claimed that it is a clone IWC 89361, actually it is modified from a Chinese chronograph movement, we call it Asia Valjoux 7750, whatever behind the solid case back, the movement can completely achieve all functions of genuine watch. Besides, the stability of this type of Asia Valjoux 7750 has been tested for more than 10 years, it is trustworthy.Watch band looks nylon on the outside, but it is actually made of calf leather, you can see it on the back side. The nylon face outside can prevent rain and water drops when washing your hands, while the genuine leather that touches your skin will bring you a great wearing comfort. So such type of band has multiple purposes. The buckle on the band is crafted very well and has a good brushing finish.The review is done, let’s appreciate their acutal photos below.
Several years ago, Panerai published Luminor Submersible 1950 PAM 382, which raised a bronze storm in watch industry. The story between XF and bronze started from Panerai’s PAM 382. Afterwards, XF unveiled PAM 507, PAM 671, Zenith Type 20 Pilot Extra Special, Tudor Black Bay Bronzo, these are all art work of XF that are made of bronze material. So, we can see that XF factory continuously researched bronze and applied this material in their watch-making process, today, they released this IWC Pilot Spitfire bronze watch, it is the first IWC watch that is made of bronze.Actually, it is not hard to make a bronze case, but the difficulty is that bronze case should be oxidized to our expected result at the speed we want, XF has always been researching this, now the oxidized result on this IWC Pilot Spitfire has achieved a perfect condition, which is closest to genuine, compared with the bronze case from small factories, you will find that their oxidized color is uneven and there is even rusty spot.
Two important IWC watches are just published by ZF factory in our market, they are from Pilot chrono series of IWC, Top Gun IW389001 and IW389002.
