A US Special Edition inspired by the mystery of underwater caves

Expressing the beauty and mystery encountered by intrepid explorers of undersea caves, this extraordinary design, available exclusively as a U.S. Special Edition, features a textured blue-green dial evoking the changing tones of mineral and stone deposits on cave walls, as well as a uni-directional rotating elapsed timing bezel in a subtle two-tone to suggest the duality of light and dark within.

Crafted of light and durable titanium, with a scratch resistant super-hard coating, the distinctive case and bracelet are sharply angled, with the precise links creating an arrow shape. The dial includes a date calendar and LumiBrite hands and markers, and is topped by a sapphire crystal with anti-reflective coating on the inner surface, while the screwdown crown and caseback, and tri-fold push button release clasp with secure lock and extender provide secure wear. Following ISO standards for scuba diving to depths of up to 200 meters, this exceptional timepiece offers manual winding capability and includes a 24-jewel automatic movement with a frequency of 21,600 vibrations per hour and a power reserve of approximately 70 hours.
