The Atlas GMT is the second ever dive watch after the Seawolf. It is a purpose driven design, where functionality and readability are elevated even in murky waters thanks to its top grade Swiss luminous pigment. At its core beats a brand new TMI NH34 GMT movement, a highly reliable Japanese caliber. GMT stands for Greenwich Mean Time, which is the 'zero hour' standard according to the Royal Observatory in London. As you move around the world, you either add or subtract hours to get the time of a second time zone. The Atlas GMT is a solid everyday watch and it can be paired with leather, rubber or leather straps.
