The GMT hand allows the time to be read in a second time zone and the hour hand can be adjusted without compromising the watch’s accuracy. This dual-time capability is the perfect function for the world traveler and is here available in a high-performance sports watch. The hour and minute hands are substantial and carry LumiBrite so as to be easily legible, day and night. The GMT hand is in orange and has a distinctive shape that makes it readable at a glance against the green dial. The screw-down crown is recessed at the four o’clock position for extra security and the watch is water resistant to 20 bar. All this, in a case that is just 40.5 mm in diameter. The convenience of GMT meets the high functionality of a true sports timepiece. Quite a combination.
