Eaton
1948–1951 · 10k Yellow Gold Filled · Manual Wind
About the Eaton
Made from 1948 through 1951, the Eaton is a slender rectangular Hamilton in a 10K yellow Gold Filled case running on the caliber 980, a 17-jewel manual-wind movement. The dial carries applied gold numerals in 18-karat gold, a noteworthy specification for a watch at this price point, with numerals at all positions except six, where a subseconds hand takes their place. The Eaton falls outside Hamilton's major named families and reads as a quietly refined dress watch from the early postwar years.
Finding an Eaton in good shape means paying close attention to those applied gold numerals, which can come loose or tarnish with age, and any that have been reglued or are sitting at an angle will affect both the look and the value. The 20mm rectangular case is compact even by dress-watch standards, which kept this one from feeling flashy; that restraint is part of what makes a clean example appealing today.
From the Catalog
Hamilton listed the Eaton at $55.00 in 1948, describing it as a Grade 980, 17-jewel watch in 10K natural gold-filled with an 18-karat applied gold numeral dial, a detail Hamilton considered worth calling out explicitly in period advertising.

What to Look For
| Dial | The applied gold numerals are the first thing to check. Look closely for any that are separating, tilted, or showing tarnish around the base. The silver dial surface should be clean and even, spotting or uneven aging in the finish can indicate moisture exposure. The subseconds dial at six o'clock should be crisp and legible. |
| Crystal | These take a flat or slightly domed acrylic crystal. Check for deep scratches or crazing, and make sure the fit is snug with no gap at the bezel edge. |
| Movement | The caliber 980 is susceptible to dried-up oil after decades of sitting unworn, and that friction alone can stop the watch entirely. If the watch is running inconsistently or not at all, a full service is almost certainly needed. Also worth inspecting: the mainspring on these movements frequently needs replacement rather than just cleaning. |
| Case | The 10K yellow gold-filled case should show even color without brass showing through at the lugs or case corners, those high-wear spots are where plating goes first. The straight lugs on this model are relatively simple, but check that none are bent or show stress cracks at the case join. |
| Crown | Confirm the crown is original or a correct replacement and that it winds and sets smoothly without slipping. A crown that spins freely without engaging the movement is a red flag for a worn or broken winding mechanism. |
The Movement
The caliber 980 is a 17-jewel manual-wind movement produced by Hamilton in the United States. It winds from the crown, keeps a subseconds display running off a dedicated wheel, and is built to a standard that was considered genuinely reliable for everyday dress-watch use in its era. It responds well to a proper service but does not tolerate neglect, oil becomes critical to its function, and a movement that has sat dry for years will need attention before it runs correctly.
