The Datejust and Date have always featured identical functions – a self-winding time and date movement with an instantaneously changing date display. Additionally, the two watches have often run on the same calibers as well (as have the smaller versions of both models) with both switching to quickset date movements in the late 1970s.However, today the current-production Datejust 36 and Datejust 41 watches are powered by the latest generation Caliber 3235 movement with a 70-hour power reserve, while the Date 34 still runs on the previous generation Caliber 3135 with a 48-hour power reserve.Overall, the Rolex Date is the smaller and simpler version of the Rolex Datejust with fewer options available from the factory but offering near-identical functionality.Holiday season is right around the corner and for many of us, that means traveling somewhere to spend some quality time with family. Whether you’re flying across the country for Thanksgiving, to another country for winter break, or voyage frequently as part of your day-to-day life, here are some of our favorite Rolex watches for women who travel.Given that the Rolex GMT-Master watch was invented for people who fly planes for a living, it comes as no surprise that this would be a top pick for a travel watch.
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.
IW389001 is in whole black, including the dial, it is the model I prefer. While IW389002 has a green dial. There is one little difference between the two watches on the dial, that is IW389002 has a red circle on the center of the dial to display 12 hours. Two subdials are positioned at 12 and 6 o’clock. The subdial with a small red hand is small seconds subdial, while the subdials at 12 o’clock have two small dials in sunken design, the outer one is 60-minute chronograph counter, while the inner one is 12-hour chronograph counter. All hour markers are in white, the markers at 3, 6, 9 and 12 o’clock are applied with luminous material, they will emit a strong green light at night.Compared with the green dial of IW389002, I like the black one of IW389001 more. It has a match of white details in blackground, which greatly increases the dial readability. Black looks cooler too.
The replica is a real chronograph watch because its basic movement is a valjoux 7750 chronograph movement. The factory modified its movement plates and auto rotor to make it look closer to genuine IWC 79350 Caliber, and they did it. When you open the case back, you can not even tell the movement difference between the replica and genuine. So you can relax and do not worry to be spotted when wearing it among your friends.Black leather strap, plus black hand stitching, perfectly match the leisure style of the replica watch. The band is made of genuine alligator leather, it will be very durable. The leather band is fitted a deployant clasp, which is brushed and features “IWC” engraving. This IWC Portuguese is very necessary for men who need a watch to fit their business suits.
