The Seiko 5 Sports SRPK33K1 is a renewed version of the famous SKX013K1. It is the contemporary, heavy-duty sports watch that marks the 55th anniversary of the 5 Sports line. Made entirely of stainless steel, this punchy blue timepiece is an offshoot of the Quartz Divers launched in the 1980s. This model is equipped with a graduated rotating bezel as well as a transparent case back that allows you to admire its automatic caliber.
