It seamlessly drives the essential functions of hours, minutes, seconds, and date - everything needed for everyday use.
The bracelet is crafted from stainless steel, seamlessly complementing the case both visually and in terms of toughness. This metal offers unmatched durability, resisting scratches and shocks while maintaining a brushed and polished look that blends aesthetics with functionality. Precisely proportioned lug width keeps the watch perfectly stable on the wrist for all-day comfort. Fitted with a deployment clasp, the watch fastens easily and securely.
