About the Judson (1964)
Made from 1964 through 1967, the Judson is a cushion-cased dress watch powered by Hamilton's caliber 686, a 17-jewel manual wind movement. The case is 10K yellow rolled gold plate with a stainless steel back, pairing a warm gold tone with the durability of a steel caseback. The dial is silver with applied gold numerals and markers at the even-hour positions, giving it a clean, symmetrical layout with a subseconds register at six o'clock. The Judson was a long-running model name in Hamilton's lineup, and this mid-1960s version represents one of the later iterations of that run.
Applied gold numerals and markers are one of the first things worth examining on a Judson. Over decades, they can lift slightly at the edges or show tarnishing, and both affect the watch's overall presentation noticeably. The cushion case shape holds up well cosmetically, but look for honest wear on the lugs and any polishing that may have softened the original lines. Examples in lightly worn condition with intact dial details are genuinely satisfying to find.
From the Catalog
Hamilton offered the Judson in two dial configurations: a two-tone gilt dial with black enamel numerals at $52.50, and an upgraded version with 18K applied gold numerals for $53. The modest price difference between the two suggests Hamilton considered the applied gold numerals a refinement worth calling out specifically.

What to Look For
| Dial | Check each applied numeral and marker closely. Lifted or shifted appliques are common on dials this age, and this one is reportedly difficult to refinish correctly if the silver has developed spots or staining. A well-preserved original dial is worth paying for. |
| Crystal | The crystal is likely a replacement at this point. Make sure it sits flush and is free of deep scratches that distort the dial view. A poorly fitted crystal can also allow moisture in over time. |
| Movement | The caliber 686 at this age almost certainly benefits from a full service. Dried lubricants create enough friction to stop the movement entirely, and reassembly of the train bridge requires careful alignment of all four wheels, so find someone familiar with the movement. |
| Case | The 10K RGP layer on the case can wear through to the steel beneath, especially on the lugs and caseback edges. Look at those areas in good light before buying. Also note that case backs on vintage Hamiltons can be stubborn to open without the right tools, so avoid pry marks around the caseback lip. |
| Crown | The crown should thread or push smoothly and set the time without slipping. A loose or difficult crown can indicate wear on the stem or the setting mechanism inside. |
The Movement
The caliber 686 is a 17-jewel manual wind movement made by Hamilton during the 1960s. It winds, sets, and runs entirely by hand, with no rotor or automatic mechanism. It's a compact movement suited to dress watch cases of this era, and while it's not especially difficult to service, the reassembly requires patience, particularly in seating the train bridge correctly over all four wheel pivots simultaneously.
