The gold-tone stainless steel bracelet flows seamlessly into a deployant clasp, while refined features—a sub-second hand, hack function for precise time setting, and three-hand configuration—speak to purposeful design. This is a watch that moves with you, whether navigating daily demands or pursuing adventure.Model 98A273 | Movement 82S5 | Automatic | Case Width 44mm | Lug Width 24mm | Water-Resistant to 200M
