Seiko Prospex 4R Compact Mechanical Diver's 41.7mm Mens Watch Cobalt Blue

Ref. SRPL51K1

The SRPL51K1 sits at 41.7mm across and 12.3mm thick, with a 49.5mm lug-to-lug span that keeps it compact on the wrist. The stainless steel case combines polished and brushed surfaces, and the cobalt blue dial is paired with a matching unidirectional rotating bezel. Pointed hands and indexes carry LumiBrite lume, with the date positioned between four and five o'clock. The screw-down crown and solid caseback support 200m water resistance to ISO diving standards. A stainless steel bracelet with a three-fold safety clasp, push-button release, and diver's extender completes the watch. Inside, the 4R35 calibre offers hand-winding, hacking, and a 41-hour power reserve.
