Dive Deeper Into Life with this Seiko Prospex Automatic Diver. The SRPB97 offers professional specifications for those with a strong sense of adventure. This Seiko Automatic watch is a mechanical watch with a self-winding mechanism. The self-winding mechanism winds the mainspring with the movement of the wearer’s wrist. The energy to drive the watch is stored within the mainspring and this watch does not require a battery. All Seiko Automatic watches have an overwind protection mechanism to prevent damage to the mainspring once it is fully wound.
