SPB481J1
Inspired by Seiko’s dive watch legacy, the Seiko Prospex SPB481J1 delivers exceptional performance, bold styling, and professional-grade reliability. This automatic diver’s watch is designed to meet the rigorous demands of underwater exploration while offering a clean, vintage-inspired aesthetic.
The watch features a cream-coloured dial with bold indexes and hands coated in LumiBrite, set within a durable 41.3mm stainless steel case. A unidirectional rotating bezel ensures precise timing, while the sapphire crystal with anti-reflective coating enhances visibility under all conditions.
Powered by the Calibre 6R55 automatic movement, the SPB481J1 offers a 72-hour power reserve and daily accuracy of -15/+25 seconds. Built for durability, it boasts 300m water resistance, a screw-down crown, magnetic resistance, and a screw case back. The stainless steel bracelet includes a three-fold clasp with a secure lock and push-button release with extender for a perfect fit over a wetsuit.
