For sale at Debonar Watches: pre-owned Rolex GMT Master II 116710LN, full set.The distinctive Rolex dial with the black bezel with Oyster bracelet makes this watch wearable for almost any occasion.Naturally, the hype surrounding the Rolex GMT-Master II ref. 116710LN is all centered around its bezel. Rolex’s newly patented material (known as “Cerachrom”) replaced the inserts used across many of the brand’s sports/tool watches, which had been made from aluminum since the 1950s. While strong and resilient, aluminum was still susceptible to scratching and fading over time from normal wear and use. Cerachrom is developed completely in-house by Rolex to be highly scratch-resistant and virtually impervious to the fading effects of UV light.Rolex created the first Oyster Perpetual GMT watch in the 1950s for Pan Am pilots who wanted a quick way to check and know the time in different timezones.Decades later, Rolex released an upgraded version of their successful pilot’s watch called the GMT Master II in 1983. The ref. 116710LN wasn’t actually the very first example of the new six-digit generation of Rolex GMT-Master II watches. That honor went to the ref. 116718LN from 2005: this solid gold model was followed by the two-tone Rolesor ref. 116713LN in 2006, and the stainless steel ref. 116710LN appeared the following year in 2007. However, the steel model was the one that everyone had been waiting for and it arrived at Baselworld 2007 sporting Rolex’s recently introduced Super Case (the GMT-Master II range was the first to feature it). Although it maintained the same time-honored 40mm case diameter as its predecessor, the overall profile was noticeably chunkier thanks to thicker lugs and crown guards nearly twice the width of the previous model. The updated case proportions were Rolex’s response to the call from many collectors to increase the dimensions of their Professional Collection models, as the trend for larger watches was in full flow at the time.
