Signature Design Features
9 O'Clock Crown Placement: The crown and chronograph pushers are uniquely positioned on the left side of the case. This prevents "wrist bite" into the back of your hand during active use or surfing.
Countdown Bezel: Features a unidirectional rotating bezel that serves as an analog countdown timer.
High-Depth Dial: Built with a concave dial ring, bold printed indices, custom-molded luminous hands, and three CD-textured subdials tracking a 24-hour clock, chronograph minutes, and running seconds.
Substantial Heft: Weighing approximately 286 grams, the solid stainless steel construction is specifically favored for larger wrists
