About the Sea-Skip
Made from 1962 through 1964, the Sea-Skip pairs Hamilton's caliber 688 manual wind movement with a stainless steel case and a dial that came in two distinct versions: a white textured dial with embossed numerals and incised markers, and a grey dial with embossed numerals and markers, both featuring luminous dots and a sweep seconds hand. The model carries a sport-adjacent character without belonging to a formal dive or field family, sitting comfortably in Hamilton's broader lineup of clean, legible everyday watches from the early 1960s. Numerals run only at 6 and 12, with markers filling the remaining hour positions.
Condition on the dial is the first thing worth scrutinizing. The embossed construction on both variants makes chips and flaking more visible than on printed dials, and the luminous dots can discolor unevenly with age. Finding one with the grey dial in clean condition is particularly satisfying, since grey dials from this period tend to show aging more prominently than white ones.
From the Catalog
Hamilton's early 1960s catalog listed the Sea-Skip with both dial options available, priced at $49.95 on strap and $55.00 on bracelet, describing it with straightforward language that emphasized the embossed construction and sweep seconds as the defining features.

What to Look For
| Dial | Look closely at the embossed numerals and markers for chips or separation, and check the luminous dots for discoloration or spotting. Both the white textured and grey dial variants can suffer from uneven aging around the lume, and the embossed construction means any damage is hard to miss. |
| Crystal | Check for deep scratches or crazing on the crystal. Replacements are available, but confirm the profile fits correctly before assuming any crystal in place is original. |
| Movement | Ask when the caliber 688 was last serviced. Dried lubricants in a movement this old generate enough friction to cause wear on the train, and on a manual wind like this one, running it unserviced accelerates that damage. A watch that winds smoothly and runs consistently has likely seen recent service. |
| Case | The stainless steel case holds up well with age, but check the lugs for thinning from previous polishing and look for dings or dents around the case edges. The case back can be tricky to open, so examine it for tool marks that might indicate rough handling. |
| Crown | The crown on the caliber 688 can detach from the stem if pulled too hard over the years. Test it gently and confirm it winds smoothly without slipping or wobbling. Also note that despite any original weatherproof rating, this watch should not be worn near water. |
The Movement
The caliber 688 is a 17-jewel manual wind movement made by Hamilton in the United States. It beats at a standard rate and is known as a solid, serviceable workhorse with no major quirks, though like any American manual wind of this era it rewards regular servicing and dislikes being run dry. The sweep seconds hand is driven from the center of the movement, giving the dial a clean, uncluttered look without a subseconds dial.
