Over the years, the GMT Master II has undergone several refinements and upgrades. In 1982, the reference 16760 debuted with a sapphire crystal, replacing the plastic crystal of previous models. The reference 16710, introduced in 1988, featured a caliber 3185 movement with improved accuracy and reliability.
