Vintage ~ 1960’s Hamilton Sea Ruler 17 Jewel 688 Mens Wrist Watch ~ Not Working

Condition: Works intermittently for 5 – 10 seconds. I do not have the equipment or skills to take apart. Highly recommend having the watch inspected/ serviced by a professional watchmaker. Made from 1964 through 1969, the Sea Ruler is a clean, sport-adjacent manual wind from Hamilton’s mid-decade lineup, running on the caliber 686 or 688 with 17 jewels.
