This is the titanium alloy chronograph made by Clebar, foremost watchmaker of Swiss-made timepieces since 1925. The watchcase is made from titanium—a naturally corrosion resistant metal that has the highest strength-to-weight ratio of any metal—and aluminum, giving the watch a weight of just over 3 oz. while providing uncompromised resilience. The watch's Swiss Ronda quartz movement keeps precise time and its suite of timekeeping tools includes a 30-minute subdial, 1/10th of a second subdial, one-second subdial, and a sweeping chronograph second hand. Sturdy spring pushers on the case are precisely calibrated to yield to the touch of a finger for exacting standards, so there is no flubbing when needing to synchronize watches, set a countdown timer, or start or stop the chronograph. The face is protected by a reflection- and scratch-resistant sapphire crystal and the tapered silicone band adjusts from 3 1/2" to 4 1/2" long to provide comfort and flexibility. A screw down caseback with water tight O-ring and the I-ring lined face ensure water resistance to 660'. The watch's lithium battery provides up to 4 1/2 years of operation before requiring replacement. 1 3/4" Diam. x 1/2" D. (3 oz.)
