Product Details
Seiko Prospex SPB481J1 combines professional diver performance with a refined resort-inspired design. Its warm ivory dial features a subtle wave pattern inspired by a calm shoreline, while the sculpted black unidirectional bezel and polished stainless steel surfaces give the watch a distinctive premium character suitable for both everyday wear and serious diving.
The watch is powered by Seiko’s Caliber 6R55 automatic movement with manual winding capability, 24 jewels and an approximately 72-hour (3-day) power reserve. The stainless steel case measures 41.3 mm in diameter and is fitted with sapphire crystal with an anti-reflective coating on the inner surface.
Built to Prospex standards, SPB481J1 offers 300 meters / 1000 feet diver’s water resistance, a screw-down crown, screw case back, LumiBrite on the hands, indexes and bezel, and a stainless steel bracelet with secure-lock three-fold clasp, push-button release and extender.
