Chronoswiss Timemaster Chronograph GMT with Second Time Zone

The Timemaster Chronograph GMT, now outfitted with a second time zone, offers homesick sports fans perfect orientation at just one glance, worldwide. This automatic chronograph can be seen as the evolution of the Timemaster Chronograph Date and includes a bright red GMT hand pointing to the bezel with its 24-hour divisions allows the second time zone to be easily read, making it a helpful partner for business as well as leisure.

Black is beautiful—which is why the Timemaster line is available in two combinations involving black: with a stainless steel case, black dial, and luminous markers and hands inlaid with white Super-LumiNova. Or the other way around: here the case is coated with innovative, ultra-hard DLC (diamond-like carbon, Dianoir®) and its dial is made to contrast with silver, effectively emphasizing the anthracite-colored luminous substance on the hands and markers.

Whether light or dark, both versions boast an extremely clean dial utilizing the bright red as its “special effect” in the date window, the GMT of the model name, and specially designed GMT hand. The latter is guaranteed to leave nothing in the dark for its skeletonized hand tip with its special shape ensures that the adjacent second markers remain precisely in focus.

The perfect connection for long or short strap preferences is guaranteed by a fully new and novel strap crafted in high-quality rubber, which is attached to the case by an innovative lug solution that is both extremely secure and aesthetically demanding.

A sporty globetrotter, the Timemaster Chronograph GMT with second time zone and date hand is at home all over the world—and thanks to its water-resistance of up to 10 atm not only on land and in the air, but also in the water it remains an uncomplicated and robust travel companion.
