Corvet
1961–1963 · 10k Yellow Gold Filled · Manual Wind
About the Corvet
The Corvet was produced from 1961 through 1963 as part of Hamilton's Medallion family, a line of dress watches built around clean dials and refined case proportions. It runs on the caliber 770, a 22-jewel manual wind movement, housed in a 10K yellow Gold Filled round case. The dial is sterling silver with 14K gold markers and painted black markers, and a subseconds hand sits at the lower portion of the dial. The Medallion family is covered in its own guide, but the Corvet represents one of its more quietly composed designs.
Silver dials oxidize and stain in ways that gold or lacquered dials simply don't, so condition varies more than average on examples that weren't stored carefully. Finding a Corvet with a clean, bright silver dial and intact 14K gold markers is the real challenge, and when one turns up that way, it rewards the search.
From the Catalog
Hamilton listed the Corvet in 1961 at $89.50 on strap, describing the dial as sterling silver with 14K gold markers and black markers, all in a 10K yellow gold-filled case.

What to Look For
| Dial | Silver dials are vulnerable to moisture and age in ways other dials aren't. Look for oxidation, staining, or spotting, especially near the edges. The 14K gold markers should be present and undamaged. Refinished dials lose significant collector value, and they're harder to spot on silver, so look closely at the surface texture under good light. |
| Crystal | Check for cracks, deep scratches, or fogging. A deteriorated crystal can allow moisture to reach the silver dial, causing damage that's difficult or impossible to reverse. |
| Movement | The caliber 770 is a manual wind and needs regular winding to run. On a movement this age, dried lubricants are a near certainty. Dried oil generates enough friction to stop the movement or make it run inconsistently, so budget for a proper service. Also note that the movement ring on movements like this is prone to verdigris, which a competent watchmaker will address during cleaning. |
| Case | The 10K yellow gold-filled case should be inspected for wear through to the base metal, particularly on the lugs and case back edges. The swept lugs on this model are prone to showing wear at their tips. Case backs on vintage Hamiltons can be tight and are sometimes damaged by improper opening attempts, so check the back edge for tool marks. |
| Crown | Make sure the crown is original and not a replacement of the wrong size or profile. Verify it winds the movement smoothly and sets the hands without slipping. A worn or damaged crown threads on early manual winds can make the watch difficult to wind reliably. |
The Movement
The caliber 770 is a 22-jewel manual wind movement, and it's one of the more capable movements Hamilton put into its dress line during this period. It needs regular winding to stay running, and on any movement of this age, the lubricants have almost certainly dried out. Dried oil creates friction that can stop the movement entirely or cause it to run erratically, so a fresh service is the starting point for any example that hasn't been recently worked on.
