About the Thinline 2027B
The Thinline 2027B was made from 1968 through 1969, appearing in a single catalog year within Hamilton's Thinline family of slim, dressy watches that defined much of the brand's late-1960s American production. The case is 14K yellow gold in a round shape, housing Hamilton's caliber 687, a 17-jewel manual wind movement. The dial is silver with applied gold markers and a subseconds hand, giving it a clean, formal look that suited the period's taste for understated elegance in gold dress watches.
Finding one in solid condition takes some patience. The 14K gold case holds up well over time, but check the lugs carefully since the hidden lug design on these Thinline cases can conceal wear or previous repair work that isn't obvious at first glance. The silver dial with applied gold markers is the thing to scrutinize most closely, as any lifting, spotting, or moisture damage there will significantly affect both the look and the value.
From the Catalog
Hamilton listed this reference at $150 in 1968, positioning it as a proper gold dress watch at a price that reflected the 14K case and the overall refinement of the Thinline line.

What to Look For
| Dial | Look closely at the applied gold markers. They can lift slightly at the edges over time, especially if the watch has seen any moisture. The silver dial should be even in tone without spotting, flaking, or water staining. |
| Crystal | Check for chips, deep scratches, or a poor-fitting replacement. A crystal that sits slightly off or has visible adhesive residue around the edge is worth flagging before purchase. |
| Movement | On a movement this age, oil dries and thickens enough to cause real friction. Confirm the watch winds, sets, and runs. A service history is a genuine plus here. |
| Case | The 14K yellow gold case should be examined for deep polishing that has softened the original lines, and for any cracks or solder repairs near the lugs. Gentle wear is normal and expected; heavy polishing removes material and changes the profile. |
| Crown | The crown should wind and set smoothly without slipping or grinding. A worn crown on a gold dress watch like this can be harder to match correctly, so it is worth confirming the original is present and functional. |
The Movement
The caliber 687 is a 17-jewel manual wind movement that Hamilton used across several of its slimmer dress watch references in this period. It is a straightforward, well-regarded movement to service, though the click spring has a tendency to dislodge during cleaning, which is something an experienced watchmaker will account for. Kept serviced and running, it is a reliable everyday driver for a dress watch.
