Chadwick
1959–1962 · 14k Solid Yellow Gold · Manual Wind
About the Chadwick
Made from 1959 through 1962, the Chadwick is part of Hamilton's Medallion line, a family of 14K gold dress watches built around American-made movements and premium dial finishing. It runs on the caliber 770, a 22-jewel manual wind movement, and was offered with a silver dial carrying applied 14K gold numerals and markers. The round case in 14K yellow gold sits at 9mm thick with 17mm lugs, keeping it slim enough for a dress shirt cuff without sacrificing presence on the wrist.
Dial variation is one of the more interesting aspects of the Chadwick. Beyond the standard numeral configuration, examples turn up with all-numeral dials, and there are awards watch versions with distinct marker and numeral arrangements at 12 and 6, including one with a 'Masterpiece' inscription. The silver dials on unrestored examples can develop a warm patina over time, which some collectors appreciate and others have refinished away, so inspecting any example closely before buying is worthwhile.
From the Catalog
Hamilton positioned the Chadwick squarely within its Medallion tier in 1959, highlighting the American-made movement as the finest made anywhere and promising exceptional performance alongside materials to match, specifically the 14K gold case and solid gold numerals and markers on a sterling silver dial. It retailed for $125 in 1959, placing it among Hamilton's higher-end dress offerings of the period.

What to Look For
| Dial | Look carefully at the applied 14K gold numerals and markers. They should sit cleanly and evenly, with no separation, gaps, or corrosion at their bases. Silver dials can develop oxidation or spotting, especially near the edges. Check for refinishing, which typically erases fine texture and leaves the surface looking too uniform. On awards watch examples, verify whether the special markers and numerals at 12 and 6 are intact and whether a 'Masterpiece' inscription is present, as these variants carry different collector interest. |
| Crystal | The Chadwick takes a domed crystal. Check for crazing, chips, or a poor-fitting replacement that sits too low or too high relative to the bezel. |
| Movement | Ask about service history. The movement ring on the caliber 770 is prone to verdigris, a greenish corrosion that can spread if the watch has been stored in humid conditions. In a caliber 770 that has been sitting unserviced, dried oil creates enough friction to stop it or cause erratic timekeeping. A movement that runs but loses or gains significantly likely needs a full service. |
| Case | Confirm the case is solid 14K yellow gold, not gold-filled. Check the case back for dents or evidence of prying. The case back can be tricky to open on these, and amateur attempts leave marks. Look at the lugs for wear-through, thinning, or solder repairs from a broken lug. |
| Crown | The crown should screw or pull out smoothly without wobble. A sticky or gritty feel when winding usually points to dried lubricant in the keyless works. Check that the crown is original to the watch, as replacements are common and not always a correct fit. |
The Movement
The caliber 770 is a 22-jewel manual wind movement made in Hamilton's Lancaster, Pennsylvania facility, and it was one of the better American movements of its era. It winds, sets, and runs with a satisfying mechanical feel, and the high jewel count reflects the Medallion line's position as a premium offering. Properly serviced, a 770 keeps excellent time and is a straightforward movement for a competent watchmaker to work on.
