AI Summary This is a hand-wound Seiko Champion Calendar 860 wristwatch, manufactured in the early 1960s. It is a series that appeared as a successor to the semi-luxury model "Chronos" at the time. "860" refers to the caliber number (movement model number). The dial is a radial-finished silver dial with three-dimensional bar indexes. Although it says "WATER PROOF," waterproof performance cannot be expected in modern times due to its antique nature.
