About the Sea Rover II
The Sea Rover II was produced from 1962 through 1965, part of Hamilton's broader line of sport-oriented stainless steel models aimed at active wearers. It runs on the caliber 688, a 17-jewel manual wind movement, housed in a stainless steel case measuring 8mm thick. The dial layout is clean and practical: a white dial with painted black Arabic numerals at 12, 3, 6, and 9, applied silver stick markers filling the remaining positions, and a sweep seconds hand. Hamilton marketed it as weatherproof, and the bracelet and strap pricing at $45 and $39.95 respectively placed it squarely in the accessible end of their sport catalog.
Finding one in good shape means looking closely at the dial, since the painted numerals on these are vulnerable to moisture damage over sixty-plus years, and any pitting or separation around the Arabic figures is a sign of past water exposure. The sweep seconds configuration gives the Sea Rover II a slightly sportier feel than the subseconds dial versions common in that era, and it reads well on the wrist despite the modest case size. The applied silver markers tend to hold up better than the painted elements, so mismatched aging between the two is something to watch for.
From the Catalog
Hamilton described the Sea Rover II as weatherproof and offered it on a strap for $39.95 or on a bracelet for $45.00 in 1962, positioning it as a capable, everyday sport watch at a reasonable price point.

What to Look For
| Dial | Look carefully at the painted black numerals at 12, 3, 6, and 9. Painted elements are the first to show moisture damage, and peeling, flaking, or discoloration around those characters signals past exposure. Check that the applied silver stick markers sit flat and haven't shifted or corroded at the edges. |
| Crystal | These originally used acrylic crystals, which scratch easily but can often be polished. Deep gouges or a hazy appearance across the surface affect legibility and will need replacement before the watch is wearable. |
| Movement | Ask when the caliber 688 was last serviced. Lubricants in movements of this age dry up and create enough friction to stop the watch outright or cause it to run erratically. A manual wind that feels gritty or stiff through the crown is a reliable sign it needs a full service. |
| Case | The stainless steel case on these holds up well, but check the lugs for thinning from past polishing and inspect the caseback for signs of forced opening. Hamilton marketed this as weatherproof, but no vintage watch with seals this old should be trusted near water. |
| Crown | Pull the crown gently to check that it moves through its positions cleanly. On movements of this type, the crown can detach from the stem if it has been pulled too hard in the past. If it feels loose or wobbly at rest, that connection needs to be inspected before the watch is worn. |
The Movement
The caliber 688 is a 17-jewel manual wind movement made by Hamilton in the United States. It winds and sets conventionally through the crown, with no automatic rotor, so keeping it running means winding it daily. The 688 is a straightforward, well-regarded caliber that responds well to a proper service and keeps reliable time once clean and lubricated.
