Prospex SRQ051J1

The Seiko Prospex SRQ051J1 is a bold, precision-driven chronograph built for performance and style. Powered by the 8R48 automatic movement, it offers a 45-hour power reserve and features a stopwatch function, date display, and 34 jewels for smooth operation.

Its stainless steel case (42mm wide, 14.6mm thick) is coated for extra durability, paired with a dual-curved sapphire crystal and anti-reflective coating for clarity. With LumiBrite on the hands and markers, a secure three-fold clasp, 10-bar water resistance, and magnetic protection, this 183g timepiece is as rugged as it is refined.
