Robust wear meets refined styling in the new Zenshin Senkei Super Titanium™ chronograph. On the wrist, the silver-tone Super Titanium™ case measures 41mm, is lightweight, scratch- and rust-resistant, with the case directly integrating into the matching bracelet for a sporty and modern look. A deeply knurled crown alongside a multi-sided bezel design adds to the watch's distinct charm, while brushed finishing techniques applied throughout further elevate the look. On the textured green dial, applied hour markers offer understated timekeeping, and a triple-register configuration displays the running seconds, a 1/5 second chronograph measuring up to 60 minutes, and a 24-hour time. A subtle date window at the 4:30 position provides daily utility. Featuring our proprietary Eco-Drive technology – sustainably powered by light, any light. Never needs a battery. Caliber number B620. Water resistant up to 100 meters.
