Inspired by Seiko's first chronographs from the mid 19060s, the Prospex SSC813 has classic looks and modern features. It's powered by a Caliber V192 movement that charges via light, eliminating the need for battery replacements and offering a six-month power reserve. It runs lumed hour and minute hands, along with a chronograph seconds hand, three sub-dials, and a date window at 4:30. The panda dial is complemented by a black tachymeter bezel and a 39mm stainless steel case with a matching bracelet.
