It features a 40 mm stainless steel case with black PVD finish, paired with a perforated calf strap. Powered by the automatic H-31 movement with 60-hour power reserve, it offers a bi-compax chronograph layout, date at 6 o’clock, and Super-LumiNova enhanced legibility. With 100 m water resistance and a sapphire crystal, it adapts seamlessly from daily wear to sporting use.
