The PHOIBOS Leviathan PY054C brings the brand's iconic dive watch into a perfectly proportioned 40mm case, offering the same rugged character and professional specifications in a size that wears comfortably on nearly every wrist.

Powering the watch is the trusted Miyota 8215 automatic movement, renowned for its reliability, ease of servicing, and long-term durability. Built for serious use, the Leviathan offers 200 meters (660 feet) of water resistance, a screw-down crown, and an impressive 15 layers of Super-LumiNova BGW9 on the hands, hour markers, and bezel for outstanding nighttime visibility.

The solid 316L stainless steel bracelet features quick-release spring bars and an on-the-fly adjustable clasp, allowing instant micro-adjustments for maximum comfort without tools.
