<P> In the early 1980s the Rolex GMT - Master II was released (although production of the original version continued alongside it until the late 1990s). Although the watch looks almost identical it uses a movement that has the additional capability of an independently adjustable quickset hour hand that can be adjusted to local time without stopping the seconds or disturbing the minutes and 24 hour GMT hand . As the watch continues to feature the rotatable bezel it is able to quickly compute any third timezone reference . </P> <P> Although the original Rolex GMT Master was available only in stainless steel, as it was conceived as a functional work watch, Rolex has been making luxury versions in both mixed steel and gold, and all - gold since the 1950s, and there are even exotic variations that incorporate elaborate designs that include precious stones . </P> <P> An updated Rolex GMT Master II was released in 2005 . This new model features a number of technical changes, such as Rolex's patented Parachrom hairspring as well as a larger Triplock crown (from the diver's watches). The new model also has several cosmetic changes, such as larger case, hands and hour markers and also a new bezel made using an extremely hard ceramic material that is designed to be more scratch and fade resistant . Also included in the update is a new and more luxurious style of bracelet that has heavier solid links and a machined clasp . The stainless steel version now joins the precious metal versions by having highly polished centre links on its bracelet . </P>
