Built for precision under pressure, the Seiko Prospex SPB483J1 is a professional-grade diver’s watch engineered for adventure. Combining Seiko’s diving heritage with modern functionality, this timepiece is designed for those who demand reliability, durability, and timeless style.

The watch features a bold blue dial with luminous hands, indexes, and a unidirectional rotating bezel — all treated with LumiBrite for superior visibility in low-light and underwater environments. Housed in a 41.3mm stainless steel case, the SPB483J1 is fitted with a sapphire crystal featuring an anti-reflective inner coating for enhanced clarity.

Powered by Seiko’s Calibre 6R55 automatic movement, it delivers a robust 72-hour power reserve and maintains daily accuracy between -15/+25 seconds. With 300m water resistance, magnetic resistance up to 4,800 A/m, and a screw-down crown, this timepiece is fully equipped for professional diving. A three-fold clasp with secure lock and extender ensures a comfortable and secure fit over a wetsuit or for daily wear.
