U.S. Special Creation Automatic Watch

This Seiko 5 Sports model is a gold-finished stainless steel automatic watch with a 42.5 mm case and blue dial. It suits wearers who want a single timepiece that moves between sport and dress settings without needing a battery.

41-hour power reserve with manual winding

The 24-jewel Caliber 4R36 beats at 21,600 vibrations per hour and stores roughly 41 hours of energy when fully wound. Manual winding lets you top up the reserve before periods of low wrist motion so the watch keeps running through sedentary days.

Check 22 mm lug width and 13.4 mm thickness

The strap or bracelet must match the 22 mm lug width, and the 13.4 mm case thickness should fit under your shirt cuffs. Verify that 10 bar water resistance meets your swimming or diving needs before ordering.
