The IWC Portuguese Annual Calendar replica is equipped with an Asia IWC 52850 automatic movement, ZF disassembled all 326 components of original movement, after lots of trials of data analysis, the clone movement looks 90% the same as original 52850, besides, its adjusting method and winding feel are 100% the same as original. Because this IWC Portuguese watch has a see-through case back, so on the replica movement, ZF factory needs to work hard on the movement decoration. The following are photos of four Portuguese Annual Calendar watches.
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.
And of course, the movements of both watches are COSC certified chronometers.But the bracelets are where we begin to see differences between the Sub and the GMT. The Submariner gets Rolex’s folding Oysterlock safety clasp with their Glidelock extension system. The GMT’s Oyster bracelet, on the other hand, buckles with a simpler folding Oysterlock safety clasp with and Easylink 5 mm comfort extension link. There have been multiple cases where the Submariner and the GMT are compared.The biggest difference between the two watches is the GMT’s additional hour hand tipped with a triangular “arrowhead.” This hand indicates the hours in 24-hour format. This fourth hand can be set independently of the main hour hand, and the 24-hour time is marked on the bi-directional rotating bezel.In fact, when moving across time zones, one can move the GMT’s regular hour hand to reset to local time without affecting the 24 hour hand’s position. This makes such adjustments easy and routine for the busy traveler.With the Submariner, choices of bezel and dial colors depending on the metal chosen means you have numerous variations from which to choose. The uni-directional bezel is marked in typical dive watch fashion of five minute increments, numbers each ten minutes, and the first fifteen minutes in one-minute tick marks.Even though the GMT features Rolex’s patented Triplock screw-down crown system, the watch is only rated to 100M/330Ft (in all metals). The Submariner is rated to 300M or 1000Ft. This is interesting, given that both watches are housed in the super case.So there you have it. The Submariner and the GMT-Master II are fraternal twins, nearly identical, but each with its own capabilities.5 of the Best Looking Rolex Cerachrom Bezels Rolex isn’t known for being particularly bold with design. However, what they are known for is being innovative, whether that’s creating their own alloys like Everose or mastering the art of hard-to-achieve colored dials. Most recently, one of their biggest innovations to roll out was their new and improved Cerachrom bezels, like those that can be found on the Rolex Daytona and GMT-Master II.Because the bezel on a watch is so exposed, it is often susceptible to shocks, corrosion, fading and scratching. Therefore, Rolex wanted to upgrade specific Professional models in their Oyster collection from aluminum bezel inserts to something much more durable. In typical Rolex fashion, they’ve created their own durable ceramic called Cerachrom – which is a mix of the words “ceramic” and the Greek word for color, “chrom.”Today, we’re looking at the best of the best of these Cerachrom bezels. The most good looking, handsome, and striking examples since this new material was rolled out.I wanted to note this one first because it just looks so different than the other Cerachrom bezels that Rolex has produced. That matte, sandblasted ceramic bezel has this effortlessly modern feel, and is kind of everything that you’d want to see out of a new material. Plus, that black bezel just totally pops against the Everose case.They said it couldn’t be done. When Rolex first unveiled their Cerachrom bezel in 2005, they did so in one solid color and actually admitted that it was just too hard to do a two-colored bezel with the material. Then in 2013, they presented us with this – a blue and black bezel that became instantly iconic. It was a great addition to the GMT-Master II lineup, but it also further illustrates Rolex’s dedication to innovation. Plus it’s totally sharp, right?This is a jaw-dropping look – that Chestnut brown monobloc Cerachrom against an icy blue dial. It’s unique, it’s beautiful, and it’s all executed so well. The Daytona is already a love-it-or-hate-it watch, so it’s fitting that they’ve chosen to go with such a bold, and frankly fun choice for the bezel here.The blue Cerachrom bezel on the Yacht-Master II is just striking. The way the bold blue contrasts against the white dial and Oyster case is just so elegant.
Actually, a lot of wrist watches have its unique background when they launch in the market. Maybe it is in memory of a famous person or a novel or a match. Yes, now I am going to introduce the replica IWC Portuguese Yacht Club. It is almost 1:1 copy from the genuine no matter its appearance or movement. This series of collection is inspired by a competitive match, it uses the Volvo ocean Race as its design background. From this replica, we can know that it reveals brave spirit which the competitors has behaved in this match fully. Thanks for the virtuosity,this excellent replica has complimented in the end. I feel so excited to see this incredible replica. Now I can not wait to show you its detail. So let’s go!
The Rolex Submariner has been a part of the Rolex catalog for well over 60 years. As expected, the famed dive watch has undergone plenty of design and mechanical enhancements over the past six decades, including the all-important timing bezel. Read on to discover all the different types of bezels of the Rolex Submariner.When Rolex debuted the Submariner in 1953, the stainless steel dive watch included a rotating bezel marked to 60 minutes to allow divers to track immersion times. The steel bezel turned both ways for simple timing adjusting, the edge of the bezel was knurled for easy gripping underwater, and the insert was fashioned from black aluminum.The printed 60-minute scale on the earlier versions included markings for every 5 minutes, alternating between batons and numerals. By the late 1950s, Rolex started to include hash marks for the first 15 minutes on the bezel followed by 5-minute markings.Around 1969, Rolex introduced the first yellow gold Submariner, the Submariner Date ref. 1680/8. Accordingly, the knurled rotating bezel was fashioned from 18k yellow gold. What’s more, the Rolex Submariner ref. 1680/8 now offered the choice of either a black or blue aluminum bezel insert and matching dial.
