Attache
1961–1962 · 10k Yellow Gold Filled · Manual Wind
About the Attache
The Attache was made from 1961 through 1962, part of Hamilton's asymmetrical dress watch offerings during the early 1960s when bold case geometry was very much in fashion. It runs on the caliber 770, a 22-jewel manual wind movement that Hamilton used across several of its better dress models from this period. The case is 10K yellow Gold Filled with an asymmetrical profile, and the sterling silver dial pairs 14K gold markers and dots with painted black markers for a two-tone effect that reads quietly luxurious rather than showy.
Finding one in clean condition takes some patience. The silver dial is especially worth scrutiny since silver dials from this era are prone to spotting and oxidation that can be difficult or impossible to reverse. The combination of asymmetrical case and silver dial with 14K gold applied markers makes the Attache a more involved watch than it might first appear, and a well-preserved example rewards the search.
From the Catalog
Hamilton marketed the Attache with 14K gold markers and dots on a sterling silver dial, alongside the 22-jewel fully adjusted movement and an unbreakable Dynavar mainspring. In 1961, the bracelet version retailed for $99.50 and the strap version for $89.50.

What to Look For
| Dial | The silver dial should be examined carefully for spotting, oxidation, or uneven patina. The 14K gold applied markers and dots are worth checking for detachment or missing pieces. The painted black markers can fade or chip, so look at them under good light at an angle. |
| Crystal | Check for deep scratches, chips at the edges, or crazing. Replacement crystals for asymmetrical cases can be harder to source than standard round ones, so condition matters more here than usual. |
| Movement | The caliber 770 is a manual wind and needs regular winding. Lubricants dry out over time, and a movement running on original oil from the 1960s is running on varnish at this point. If the watch feels stiff to wind or loses time inconsistently, service is overdue. |
| Case | The 10K yellow gold-filled case should be checked for wear-through at the lugs and high points where the base metal may show through. The asymmetrical shape means uneven wear is common depending on how the watch was stored and worn. Case backs on watches this age can be tight, so look for evidence of prying around the edge. |
| Crown | Pull the crown gently to confirm it moves between positions without slipping or grinding. A worn crown on a movement this age can be a sign of deferred maintenance throughout. |
The Movement
The caliber 770 is a 22-jewel manual wind movement, one of Hamilton's more refined domestic calibers from this era. The higher jewel count reflects Hamilton's use of jewels at additional wear points beyond the standard configuration, contributing to both accuracy and longevity when properly serviced. It's a robust and well-regarded movement that holds time reliably and responds well to a proper service.
