40 mm diameter
The present watch is a reference 16700, which was introduced in 1988. It featured an array of upgrades, including a sapphire crystal, white gold indexes and a new case design. It is important to note that this reference is not fitted with the quick hour change that came slightly later with the reference 16710 GMT-Master II. The present watch is fitted with an iconic red and blue bezel. Fondly dubbed by enthusiasts as “Pepsi”, the blue and red bezel of the present watch has aged delicately into tints of cobalt blue and rose, adding some personality to the watch.
