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.
Part of the brand’s collection since 1945, the Rolex Datejust is the ultimate everyday luxury watch. While the model comes in a vast assortment of styles including different sizes, metals, bracelets, bezels, and dial designs, what remains constant across all Datejust watches is its time and date functionality. The hour, minute, and seconds hands are always placed at the center while the date window is always found at the 3 o’clock position. In true Rolex fashion, the Datejust watch is easy to use and operate but there are a few things to keep in mind when setting the time and date. Read on for our quick guide on how to set the date and time on a Rolex Datejust.Earlier models of the Rolex Datejust did not yet have the quickset date feature. A quickset date feature means that the date can be set independently from the timekeeping hands. Conversely, on a non-quickset Datejust, the minute and hour hands have to be advanced past midnight to change the numeral in the date window.Rolex introduced the quickset date function to the Datejust lineup in 1977 with the introduction of Caliber 3035 movement. So if your Datejust was made in 1977 or later and is powered by Caliber 3035 or subsequent movements (Cal. 3135, 3136, or 3235) then it has the quickset feature.Regardless of when a Datejust was produced, they all come equipped with a screw-down winding crown to ensure the watch’s water resistance. Therefore, a Rolex winding crown must be unscrewed first before any adjustments can be made.
OM started to make their reputation when they published the first Speedmaster Chrono with full functional hour and minute counter. In recent years, OM expanded their business to other models like Omega Seamaster and Audemars Piguet Royal Oak, now, I see the potential this factory has, it has the ability to become a big factory.Today, I want to introduce one Omega Seamaster Diver replica watch from OM factory, it is the latest model whose dial has wavy texture. Before, the dial only has black and blue options, now, OM also offers this white dial option. Compared with the black and blue dial version, this one with white dial is my favorite.First, I do not like this Seamaster watch just because it uses a wavy texture dial. Why did Omega abandon their smooth black dial and adopt this wavy dial? I do not think this wavy dial is more classic. However, on this model, its white dial just smoothens the wavy texture, I did not even notice it if I have not checked carefully. Like the black bezel, the white dial uses real ceramic material, the black bezel matches the white dial perfectly, it makes the watch look more classic than the one with black dial. On the dial, both hour markers and hands are filled with white luminous material, in dark condition, you will see two different lume light emitting from the dial, OM factory makes the dial lume correct. The only flaw which I can find from the dial is that the edge of hour markers is a bit thick. Check the date font shown in the window opened at 6 o’clock, although it is centered, but the date font is not made to be perfect.
So, we can see how charming these vintage watches are. This time, I will introduce a classic vintage Submariner from BP factory, it is Ref.5508.Rolex Submariner Blue Watch 5508When you first see this watch, you will be attracted by its blue color. yes, both bezel and dial are in blue. With chocolate nato strap, the watch will bring you a visual striking at first. In my experience, every vintage Rolex I saw in replica watch world is either equipped with a rivet steel bracelet or a nato band. If you want both, that is ok. The case is measured to be 38.5mm in diameter, which is a little smaller than modern Submariner. The lugs are brushed, the vintage Rolex crown is also different from modern Rolex’s. Blue bezel insert is metallic made with white printed markers, those bezel markers are not applied with luminescence except the bezel pearl that is filled with white luminous material. By the way, the bezel clicking tooth is not that as deep as that on modern Submariner watches.Blue Vintage Submariner Rolex CrownTo identify this replica Rolex as a vintage Submariner, you can easily tell by observing is blue dial. Hour markers and hands are applied with patina luminescence, not white. Those patina luminous material will emit strong green light at night. The white printed Rolex Crown is not silver three-dimensional Rolex logo, other printings such as “100m=330ft” and “SUBMARINER” are all white, which forms a high contrast with the blue background. Like we said before, the watch has a chocoate nylon strap, however, the clasp does not have a fastening Rolex Crown buckle. If you requested, I can get you one extra pair of that band. At last, the Rolex vintage 5508 replica watch is equipped with a Swiss ETA 2836-2 automatic movement, so we guarantee that its daily inaccuray will not exceed 3 seconds, we have tested this in factory.Replica Rolex Submariner 1680 Gilt Dial Replica Rolex Vintage Submariner Watch.Replica Rolex Submariner 1680 Rolex Submariner watch is definitely best of the best, classic of the classic in watch field.
