This is the Swiss-made diver's watch that can descend to the dark bathyal or "midnight" zone of the ocean—more than a mile below the sea. The self-winding watch can withstand 200 atm of pressure, while its screw-in crown, O-rings, and I-rings seal out moisture. Its non-reflective, scratch-resistant sapphire crystal and luminous hands and dials provide easy visibility while exploring caves or shipwrecks, and a valve at the 9 o'clock position automatically releases any helium buildup after a deep dive. Engineered for underwater adventurers by a Swiss watchmaker founded in 1925, the timepiece has a precise 25-jewel automatic movement. The band and case are made from 316L stainless steel plated in durable, black PVD coating with a solid-plate extension buckle that fits over most wetsuits. The unidirectional bezel ratchets 120 points to mark each half-minute. Water-resistant down to 6,600' Presented in a handsome gift box. Case 2" Diam. x 3/4" D. (9 1/2 oz.)
