Circa 1968-1971.
Featured here is a vintage Hamilton Sea Beach III in a stainless steel case with a silver finish dial and reflective outer ring with rectangular markers. This watch looks sharp all around with only light scratches seen under magnification. There is a logo of a horse (brand unknown) done in black on the lower half of the dial. The watch sets and winds smoothly thanks to a serviced caliber 688 manual hand wind movement with 17 jewels that kept good time over a 24 hour period. The case measures approximately 33mm wide x 40mm in overall length. The inside back case reads: Hamilton W. Co., Lancaster PA., Stainless Steel, P219732, Star W.C. Co., 918868.
