About the Thinline 5002
Made from 1964 through 1966, the Thinline 5002 is part of Hamilton's Thinline family, a line built around slim profiles and clean, dressy aesthetics that became a signature of Hamilton's mid-1960s catalog. The watch runs on either the caliber 686 or 687, both 17-jewel manual wind movements, housed in a stainless steel case with a matching bracelet option. The dial is silver with raised gold numerals and markers, with a subseconds register at 6 o'clock giving it a quietly formal look.
Raised gold numerals and markers hold up well over time, but check them closely under good light for any that have shifted, separated at an edge, or show adhesive residue from a past repair. The stainless case and bracelet combination was part of the original offering, though many examples surface today on replacement straps, so finding one with the original bracelet intact is genuinely satisfying.
From the Catalog
Hamilton listed the Thinline 5002 at $69.50 with the stainless bracelet included, positioning it as a shock-resistant, anti-magnetic dress watch with an unbreakable mainspring and Durapower waterproof protection when seals were intact. The strap version came in slightly less at $65.00, making the bracelet configuration the featured option in the original listing.

What to Look For
| Dial | Look at each raised gold numeral and marker carefully. Any that have detached, shifted position, or show a gap at the base are difficult to fix without a full dial restoration. The silver finish can also develop uneven aging if moisture ever got in, so check for spotting or haze, especially near the subseconds register. |
| Crystal | Check for deep scratches or chips at the edges. A correct replacement crystal is straightforward to source, but an ill-fitting one can compromise the Durapower seal that gives this watch its waterproof rating. |
| Movement | The click spring in the caliber 687 is prone to dislodging during cleaning. Ask whether the watch has been serviced and, if so, who did the work. A movement this age with dried oil will run sluggishly or not at all, so a recent service from someone familiar with these calibers matters. |
| Case | The stainless case is durable but check the lugs for wear at the lug tips and the caseback for evidence of prying rather than proper case knife technique. Deep gouges around the caseback edge usually mean it has been opened carelessly at some point. |
| Crown | Wind the crown slowly and feel for any roughness or slipping. The Durapower designation means the seals matter here, so a crown that wobbles or sits proud of the case is worth flagging before purchase. |
The Movement
The caliber 686 and 687 are closely related 17-jewel manual wind movements that Hamilton used across several Thinline models in this period. Both are hand-wound, meaning you advance the mainspring by turning the crown, and both are solid everyday movements when properly serviced. The 687 is the more commonly encountered of the two and responds well to a careful service, though the train bridge alignment during reassembly requires patience to get right.
