The Seiko 5 Sports SKX Series SRPJ45K1J pays homage to the iconic SKX design while delivering modern automatic performance for everyday wear. Its 42.5mm stainless steel case provides a confident wrist presence, complemented by a unidirectional rotating bezel that enhances its sporty, functional character. The dial is protected by a durable Hardlex crystal and features generous LumiBrite on the hands, indexes, and bezel for excellent visibility in low-light conditions. Powered by the Seiko Caliber 4R36 automatic movement, the watch offers manual winding capability, a stop-second function, and a dependable 41-hour power reserve supported by 24 jewels. A practical day and date display adds daily convenience, while the see-through screw case back reveals the mechanical movement within. Finished with a stainless steel bracelet secured by a three-fold clasp with push-button release, this model is water resistant to 10 bar and built for reliable daily and aquatic use.
