Thinline 2001
1960–1961 · 14k Solid Yellow Gold · Manual Wind
About the Thinline 2001
Made from 1960 through 1961, the Thinline 2001 is part of Hamilton's original Thinline family, which brought a new emphasis on slim, refined proportions to their American-made dress watch lineup. The case is 14K yellow gold, round in shape, and houses the caliber 676, a 17-jewel manual wind movement. Hamilton marketed this watch as part of a group defined by new super-slim styling, and the 2001 carries that brief well, with a clean white dial and applied gold markers and no hour numerals to interrupt the minimalist layout.
Finding one in good shape means paying close attention to the dial, because the white finish and applied gold markers on these can suffer from moisture intrusion over six decades. The hidden lug design also means case condition takes a bit more scrutiny than a standard lug, since damage there can be easy to overlook at first glance. The two-year production window means examples don't surface constantly, so a clean original dial is genuinely worth pausing for.
From the Catalog
Hamilton described the Thinline 2001 in 1960 as part of a new group bringing super-slim styling to their lineup, with a luminous dial, applied 14K gold markers, and weatherproof construction. It retailed for $135.00 on strap.

What to Look For
| Dial | Look closely at the white dial for spotting, discoloration, or separation around the applied gold markers. Moisture damage tends to appear first near the edges or around any markers that have shifted slightly over time. A clean, flat, unrestored dial is the hardest thing to find on these and the most important. |
| Crystal | Check for deep scratches or chips. A replacement crystal is not a dealbreaker, but make sure it sits flush and is proportioned correctly for the case, since an ill-fitting crystal on a dress watch reads immediately. |
| Movement | Ask when the caliber 676 was last serviced. Oil in a movement this age dries out, and dried lubricant creates enough friction to degrade timekeeping noticeably before the watch stops altogether. A watch running when you receive it is not the same as a watch that has been properly serviced. |
| Case | The hidden lugs are worth a careful look. They can crack or thin out from years of strap changes, and because they're less visible than standard lugs, wear there can go unnoticed. Also check the case back for dents or evidence of forced opening, since these backs can be tricky to open correctly. |
| Crown | Check that the crown threads and seats properly and that the stem engages cleanly through its positions. On a weatherproof case, crown condition also affects the seal, though no vintage watch should be treated as water-safe regardless of its original rating. |
The Movement
The caliber 676 is a 17-jewel manual wind movement made by Hamilton in the United States. It's a slim, straightforward caliber built for dress watch applications, which is exactly what the Thinline series called for. The movement winds smoothly when serviced properly, but the balance jewels are very small and easy to lose during service, so it benefits from a watchmaker who knows these movements well.
