Gramercy
1958–1961 · 10k Yellow Gold Filled · Manual Wind
About the Gramercy
Made from 1958 through 1961, the Gramercy is a rectangular 10K yellow Gold Filled dress watch built around Hamilton's caliber 770, a 22-jewel manual wind movement. The dial is sterling silver with applied 14K gold markers and dot indices, a combination that gives the watch a quiet richness that photographs poorly but looks genuinely beautiful in person. The Gramercy shares family DNA with the Gary and Carlton, a trio of similarly proportioned rectangular models from the same era that share a design sensibility without being identical.
Silver dials from this period can develop a warm patina or, in less fortunate cases, spotting or discoloration unevenly if moisture has gotten under the crystal over the decades. The 14K gold markers are a detail worth verifying in person, since later examples or refinished dials sometimes show inconsistencies in finish or adhesion that a good photograph will hide. A clean, original example with a matched silver butler finish dial is the version collectors tend to hold onto.
From the Catalog
Hamilton offered the Gramercy in its 1958 catalog with 14K gold markers and dots on a sterling silver dial, available on a bracelet for $100.00 or on a strap for $89.50. The bracelet configuration was the more dressed-up option Hamilton positioned for buyers who wanted the full look.

What to Look For
| Dial | Silver dials can tarnish or develop uneven patina when exposed to moisture over the years. Look for consistent color across the surface and check that the applied gold markers and dot indices are all present, flush, and free of separation at the edges. Any refinishing typically flattens the fine texture of the original finish and is hard to undo. |
| Crystal | Check for chips, deep scratches, or a replacement crystal that sits proud of the bezel or distorts the dial underneath. A correct crystal matters more on a rectangular case like this, where the geometry is part of the watch's character. |
| Movement | Ask about service history. The caliber 770's movement ring is prone to verdigris, a greenish corrosion that forms when moisture gets into the case and reacts with the brass ring that holds the movement in place. A watchmaker opening this one for service should check for it specifically, and if it's present, it needs to be addressed before the watch goes back together. |
| Case | Examine the lug ends carefully and look for any brass showing through. Case backs on these can be tricky to open without marring the edges, so signs of pry marks around the back are worth noting. |
| Crown | Make sure the crown is original to the watch and not a generic replacement. A mismatched crown is easy to overlook but does affect the finished look. Check that it winds and sets smoothly without slipping or grinding. |
The Movement
The caliber 770 is a 22-jewel manual wind movement that Hamilton produced domestically in Lancaster, Pennsylvania. It runs at 18,000 beats per hour and drives a subseconds hand via a small register at the dial. The higher jewel count relative to Hamilton's more common 17-jewel movements reflects the manufacturing tolerances Hamilton held on this caliber, and it runs well when properly serviced.
