The GMT Master II ref. 16710 is one of the most iconic and influential examples of the brand’s multi-time zone pilot’s watch. It brought an upgraded case and movement to the line, making it a huge success and leading to its impressive production run of almost twenty years. The ref. 16710 was then replaced by the ref. 116710 in the late 2000s as a completely new generation of Rolex GMT-Master tool watches began to make an appearance with a brand new case and bracelet design, improved materials, and a new movement.Rolex developed the GMT-Master in the early 1950s at the request of Pan Am Airlines. Its release came during the dawn of international flight. The famous air carrier required a dual-time wristwatch to issue their pilots, and the GMT-Master was born. The GMT-Master II was released a number of years later in 1983 with the ref. 16760, and brought with it independent hour hands that allow the wearer to read two time zones on the dial and a third on the bezel.The first GMT-Master II ref. 16760 featured a bulkier case and is often referred to by avid collectors as the “Fat Lady” or “Sophia Loren.” In 1989, Rolex would release a refined variation of the Fat Lady GMT in the form of the sleeker reference Rolex 16710 with a thinner case and movement. The ref. 16710 was well-received among collectors for its upgraded case and movement, and it would go on to become one of the most successful GMT-Master II models, remaining in production for nearly twenty years.A completely redesigned version of the stainless steel Rolex GMT-Master II was introduced in 2007, which meant the discontinuation of the long-running ref. 16710. The Rolex 116710 is similar in design as its 5-digit predecessor with an all-steel finish, a perpetual movement with independent hour hands, and a bidirectional bezel; however, that’s where its similarities end. The ref. 116710 is almost an entirely new watch and boasts a redesigned bezel, case, bracelet, and dial, as well as the newer Caliber 3186 perpetual movement.
Compared with other common IWC Mark series models, this Mark XVIII titanium watch is very outstanding. Grey Titanium case, track-style minutes markers, brown dial and brown leather straps, these elements make the watch full of vintage flavor. The replica is a really a big surprise from GS factory.IWC Portuguese is a very famous watch and it is one of the best-selling dress watches in the world. In our watch market, there are three factories at least that are manufacturing IWC Portuguese watches, ZF, YL and 3A. Among them, ZF is the biggest and most famous one. Actually ZF makes the best quality replica IWC Portuguese watch, they are also the first factory that started to clone genuine IWC Caliber. Like this replica, ZF equipped a clone 79350 movement inside, this is a great improvement, because it is the first time for a factory to use a cloned IWC Caliber in a IWC Portuguese chrono replica watch, we only saw factories used such type of movements in IWC non-chrono Portuguese. The replica is a V2 edition, the V1 uses an Asian Valjoux 7750 movement, now the V2 uses a new clone 79350 like genuine IWC Caliber. This is the biggest difference, while there are certainly other improvement made on this latest version, let’s check it carefully in the following article.
