The GMT-Master II featuring an entirely redesigned case, a larger winding crown, a revised dial with modified indexes and green "GMT-Master II" signature was launched at the Baselworld 2006, year of the 50th anniversary of this celebrated dual time wristwatch.
The present watch is from the series of three precious stone-set GMT-Master II models, introduced at the same time. It is distinguished by its diamond, sapphire and ruby-set bezel, a tribute to the blue and red coloured bakelite bezel of the first GMT Master model launched in 1956.
