About the Thinline 2017
Made from 1966 through 1967, the Thinline 2017 is part of Hamilton's Thinline family, a series built around slim case profiles and clean, uncluttered dials. It runs on the caliber 687, a 17-jewel manual wind movement, and was offered in both 14K white gold and 14K yellow gold. The round case pairs with a silver dial carrying applied gold stick markers and a subseconds hand, giving it a spare, refined look that fits squarely with what Hamilton was doing in the mid-1960s as dress watch proportions kept shrinking.
Finding one in solid condition takes some patience, mostly because the gold cases invite scrutiny around the lugs and case back edges where wear tends to concentrate. The dial is worth a close look too, since silver dials from this period can develop patina unevenly, and the applied markers can show separation from the surface if the watch was exposed to moisture over the years.
From the Catalog
Hamilton described the Thinline 2017 in 1966 with an emphasis on its ultra-thin case design, listing it as shock-resistant, anti-magnetic, and fitted with an unbreakable mainspring. It retailed for $175 in 14K gold, positioning it as a serious dress watch in Hamilton's lineup for that year.

What to Look For
| Dial | Look closely at the applied gold stick markers for any signs of separation or misalignment. A silver dial from 1966 may have developed some patina, which is normal, but uneven discoloration or staining near the markers can point to past moisture intrusion. |
| Crystal | Check the crystal for scratches and for how well it seats in the bezel. A poorly fitting crystal on a watch originally rated waterproof-dustproof can let dust or humidity reach the dial over time. |
| Movement | Ask when the caliber 687 was last serviced. Oil in a movement this age dries out completely, and the resulting friction is often enough to stop the watch or cause it to run erratically. A service history helps, but opening the case back and eyeballing the movement condition is always worth doing. |
| Case | In 14K gold, the case edges and lug corners are the first places to show polishing wear. Look for softened lug profiles or evidence of aggressive buffing, which can remove detail and thin the case over decades of cleaning. |
| Crown | Test the crown through winding and hand-setting. It should feel smooth and positive without slipping. A worn crown on a watch with waterproof-dustproof seals originally intact means those seals have almost certainly not been maintained, so treat this as a dry-storage piece regardless of original specs. |
The Movement
The caliber 687 is a 17-jewel manual wind movement that Hamilton used across several of its dress models during this period. It is a relatively straightforward movement to service, though the click spring has a tendency to dislodge during cleaning, which requires care. Wind it daily and it rewards you with dependable, accurate timekeeping.
