Seiko 5 SKX SRPJ45K 'Time Sonar' Automatic

First introduced in the 90s, the Seiko 5 Sports SKX watches modernized the classic designs from the 1960s, enhancing their reliability and durability. The 90s collection featured improved practicality, including better water resistance, stronger crystals, and luminous hands and hour markers. These enduring qualities remain integral to the Seiko 5 Sports line today.

With its classic look and signature Seiko finish, this timepiece perfectly blends form and function. The stainless-steel case is complemented by a see-through blue dial and a blue and black bezel, featuring a day and date display along with lumibrite hands and markers.

The Seiko 5 Sports SRPJ45K is powered by the Seiko Caliber 4R36 automatic and manual winding movement with 24 jewels, offering a power reserve of approximately 41 hours and a daily accuracy of +45 / -35 seconds. The case measures 42.5mm x 13.4mm in stainless steel, with a lug-to-lug size of 46mm and a lug width of 22mm. With a water resistance rating of 100m and an approximate weight of 170g, this watch also features a screw-down case back, a see-through exhibition back, and a day and date function.

The "5" in Seiko 5 represents the five key features that define each watch: an automatic movement, day-date display, water resistance, recessed crown, and durable case and bracelet.
