TSUYOSA 60

The TSUYOSA 60 combines Japanese precision engineering with understated elegance. Its 40mm stainless steel case with yellow gold-tone finish strikes a balance between presence and wearability, while the integrated bracelet and deployant clasp ensure secure, comfortable wear. The silver-tone dial features applied indices and a practical date window. Powered by the automatic caliber 8310 movement, this timepiece delivers 60 hours of power reserve—enough to keep running through weekends away from your wrist. Sapphire crystal resists scratches for lasting clarity, and 50-meter water resistance handles daily water exposure. A true self-winding mechanical watch that rewards consistent wear with reliable performance
