Automatic K-202
1956–1959 · 14k Solid White Gold / 14k Solid Yellow Gold · Automatic
About the Automatic K-202
Made from 1956 through 1959, the Automatic K-202 is part of Hamilton's Automatic family and runs on the caliber 661, a 17-jewel automatic movement. The case came in both 14K yellow and 14K white gold in a clean round profile, paired with either a white or black dial featuring applied 14K gold markers and a pearled minute track. Hamilton also specified Silhouette hands on this model, with luminous material on the underside rather than the top surface, giving the dial a cleaner look in daylight while still offering low-light legibility.
Silhouette hands are the detail to pay close attention to here. Because the hands sit so close to the dial surface, heat and friction from inadequate clearance has caused burning on more than a few original dials, particularly on black examples. Finding one with a clean, unmarked dial is the real goal, and it's worth examining closely before purchase.
From the Catalog
Hamilton's 1957 catalog described the K-202 as offering 14K gold markers and a pearled track on either a white or black dial, with Silhouette hands whose luminous material was applied to the underside. Both dial options in yellow or white gold were priced at $175.00.

What to Look For
| Dial | Look carefully for burn marks near the center of the dial and along the path the hands sweep. The Silhouette hands sit close to the surface, and contact or heat buildup has damaged original dials on a meaningful number of examples. Any discoloration, scorch marks, or ghosting near the center arbor is worth factoring into your evaluation. The applied gold markers and pearled track should be intact and sitting flat. |
| Crystal | This case opens through the crystal rather than the case back, which means the crystal takes the brunt of any service access over the years. Check for chips, deep scratches, or evidence of prying at the crystal edge. A replacement crystal is common on serviced examples. |
| Movement | The caliber 661 is an automatic, and dried oil creates enough friction to stop it entirely on examples that have sat unserviced for years. Confirm the watch winds, runs, and the rotor spins freely. Ask about service history. |
| Case | The case is 14K gold, either yellow or white, so check for deep wear through plating at the lugs and case sides. Also look at the case back for pry marks or tool damage from anyone who tried to open it from the back, not knowing the correct access point is through the crystal. |
| Crown | Hamilton listed this model as waterproof, but no vintage watch should be considered water resistant at this point regardless of original ratings. Check that the crown threads in smoothly and seals without play or wobble. |
The Movement
The caliber 661 is an American-made 17-jewel automatic that Hamilton used across several of its round-case models during the 1950s. It winds via a rotor as the watch moves on the wrist, so it keeps itself wound with regular wear. It's a reliable movement when properly serviced, though getting the oscillating weight carrier seated correctly back onto the movement during a service takes some patience.
