Seiko Men's Prospex Automatic Watch SRPH77J1

Water-ready and built to a diver's standard. Here, the Seiko Men's Prospex Automatic Watch SRPH77J1 frames a blue dial in a 43.22mm case.

Inside, the automatic Calibre 4R35 winds itself with the motion of your wrist, and can be wound by hand when it has been resting. Off the wrist, it keeps running for around 41 hours. With 20 bar diver's water resistance, it is rated for scuba diving. Seiko backs it with a three-year international warranty. Made in Japan.
