About the Sea-Scout B
Made only in 1961, the Sea-Scout B is a stainless steel sport watch running Hamilton's caliber 673, a 17-jewel manual wind movement. It was offered with a choice of embossed luminous white or black dial, both sharing the same bold numeral layout at 3, 6, 9, and 12 with a subseconds register. The Sea-Scout B is part of Hamilton's broader Sea-Scout line, which brought rugged, legible styling to the sport and utility end of the catalog.
Finding one in honest, unpolished condition is the goal here. The embossed dials are a distinctive feature of this model and they do not respond well to refinishing, so originality matters more than usual. Collectors should note that Hamilton offered this watch with either a bracelet at $45.00 or a strap at $39.95, and period bracelet survivors add a nice layer of completeness to any example.
From the Catalog
Hamilton described the Sea-Scout B simply and accurately in 1961: a stainless steel case with an embossed luminous dial available in white or black. Pricing started at $39.95 on strap and reached $45.00 with a bracelet, placing it at an accessible but serious point in Hamilton's sport watch lineup.

What to Look For
| Dial | Examine the embossed numerals and markers closely. Refinished dials often lose the crispness of the original texture and the luminous material can look uneven or overly bright if touched up. Both white and black versions should have luminous fill that shows age-appropriate patina, not fresh paint. |
| Crystal | Check for chips or crazing around the edges. A well-fitting replacement crystal is acceptable, but make sure it sits flush and does not press on the dial. |
| Movement | Ask when the caliber 673 was last serviced. Oil hardens in movements of this age, and a manual wind that has been sitting dry will build enough friction to cause real wear on the gear train. A watch that winds smoothly and runs consistently at the wrist is a good sign, but it is not a substitute for a proper service. |
| Case | Swept lugs like these are prone to over-polishing, which rounds off the lug tips and softens the case profile. Look for a case that still shows some definition at the edges. The caseback can be difficult to open on examples like this, so check whether it has been forced in the past. |
| Crown | The original crown should be correct in proportion to the case. Also note that even though the Sea-Scout B was described as weatherproof, vintage watches of this age should not be treated as water-resistant today. Seals and gaskets from the 1960s are long past their service life. |
The Movement
The caliber 673 is a 17-jewel manual wind movement from Hamilton's American production era, compact and reliable when properly serviced. It winds from the crown and requires no rotor, making it a straightforward movement to regulate and maintain. Josh considers movements like this one among the more satisfying to work on, provided they have not been run dry for years.
