About this watch

Seiko 5 Sports “Time Sonar” SRPJ47K1

The SRPJ47K1 brings one of Seiko’s most distinctive vintage designs into the Seiko 5 Sports SKX case. Its translucent amber dial reveals the rotating day and date discs beneath, creating the layered look inspired by the original 1970s “Time Sonar.” A black and copper-tone rotating bezel, luminous markers, and stainless steel bracelet complete its striking look.

Inside is Seiko’s 4R36 automatic movement, which can also be wound by hand and offers approximately 41 hours of power reserve. The watch features a day/date display, Hardlex crystal, exhibition caseback, and 100 meters of water resistance. (Seiko Watch Corporation)
