About the Donavan (1955)
The Donavan appeared in a single catalog year, 1957, making its production run brief even by Hamilton's standards for limited dress models. It carries a 14K yellow gold rectangular case and a silver dial set with applied gold numerals and six diamonds at the 2, 4, 8, 10, and 12 positions, with a subseconds register at 6 o'clock. Power comes from the caliber 770, a 22-jewel manual wind movement that Hamilton used extensively through the mid-to-late 1950s in its finer dress watches. Hamilton's catalog noted an alternate marker dial version as well, so two dial configurations exist for this reference.
Finding a Donavan in honest condition takes some patience. The silver dial is prone to oxidation and light spotting over the decades, so look carefully at how the dial surface reads under good light before committing. The diamonds are small but their presence matters to value, and any sign of a replaced stone or missing setting deserves attention.
From the Catalog
Hamilton listed the Donavan at $250.00 and described the dial as sterling silver with 14K gold numerals and six diamonds. The catalog also directed buyers to a marker dial version on a separate page, suggesting Hamilton offered two distinct dial configurations for this reference.

What to Look For
| Dial | Silver dials oxidize over time. Look for even patina rather than dark spots, staining, or evidence of cleaning attempts that have gone too far. Confirm all six diamonds are present and that none of the settings appear disturbed or re-tipped. |
| Crystal | Check for chips, deep scratches, or a replacement that doesn't sit flush with the case profile. A proper crystal matters more on a rectangular case, where fit is more exacting than on a round. |
| Movement | Oil dries out over decades, and enough friction can build up to stop the movement or cause erratic timekeeping. A Donavan that hasn't been serviced recently should be treated as needing a full service before regular wear. |
| Case | This is a 14K gold case, so inspect the surfaces for deep polishing that has softened the edges or removed detail. Sharp lugs and crisp proportions are what you want. Verify gold content with a loupe if the hallmark is worn. |
| Crown | The original crown should match the case metal. A replaced crown in a mismatched metal or wrong size is a small detail, but it affects both appearance and how well the stem seals the movement from dust. |
The Movement
The caliber 770 is a 22-jewel manual wind movement that Hamilton developed for its upper-tier dress watches in the 1950s. It runs at 18,000 beats per hour and is known for solid reliability and good accuracy when properly serviced. The jewel count reflects genuine quality engineering rather than cosmetic inflation, with each jewel placed where it reduces friction in the gear train and escapement.
