This is the Anonimo Militaire Zulu Time. It is a GMT automatic watch with a sand blasted stainless steel case. The case is 43 mm in diameter and may not be that big, but they say the watch case is very thick. The watch features a patented crown vanishing locking device that is integrated with the watch strap. Manufactured and hand finished in patented Kodiak process calfskin to allow for extended immersion in fresh and sea water (up to 24 continuous hours). The Zulu Time from Anonimo is available for $4600.
