Watson
1936–1939 · 10k Yellow Gold Filled · Manual Wind
About the Watson
The Watson ran from 1936 through 1939, a four-year production run in a tonneau case cut from 10K yellow Gold Filled metal. It runs on either the caliber 987E or 987A, both 17-jewel manual-wind movements that Hamilton used across a range of models during this period. Hamilton offered the Watson in one case finish only, natural yellow, but gave buyers a choice between two dial configurations from the start. It shares close family ties with the Webster, a related model from the same era with a similar sensibility.
Finding one with an original applied gold numeral dial is the better outcome of the two variants. The gold finish black numeral dial was the more affordable option at the time, listed at $37.50 against the $40.00 price of the applied numeral version, and those dials have had more than eighty years to show wear. On either version, inspect the dial carefully for separated or missing numerals, and check the case for the wear patterns common to this style of Gold Filled tonneau.
From the Catalog
Hamilton's 1936 catalog offered the Watson in natural yellow only, with the applied gold numeral version priced at $40.00 and the gold finish black numeral dial version at $37.50, a modest difference that reflected the simpler construction of the printed dial option.

What to Look For
| Dial | Two dial variants exist: an applied gold numeral dial and a gold finish black numeral dial. On the applied numeral version, check each numeral individually for separation or loss, especially at 12 and around the lower registers where moisture can wick in. On the black dial variant, look for fading, crazing, or gold finish loss. Note that 6 o'clock has no numeral, with a subseconds dial occupying that position. |
| Crystal | The 10K gold-filled case is prone to wear-through at the top and bottom of the crystal seat. Look at those edges closely before buying. A replacement crystal can hide or complicate this, so check the fit and whether the original profile has been compromised. |
| Movement | Lubricants in a caliber 987E or 987A of this age have almost certainly dried out. That dried friction alone can cause erratic timekeeping or stop the watch entirely. A service history from within the last few years is worth asking about before assuming the watch is running well. |
| Case | Beyond the crystal seat, pay close attention to the corners near where the tubes join the case. This is the other high-wear zone on gold-filled tonneau cases of this style, and wear-through exposes the base metal beneath. Turn the case in hand and check these transition points in good light. |
| Crown | Check that the crown winds and sets smoothly without slipping or grinding. Case backs on watches of this era can be tricky to open, so if there is no recent service documentation, plan for a watchmaker to assess what is inside before putting the watch into regular wear. |
The Movement
The Watson uses either the caliber 987E or the 987A, both 17-jewel manual-wind movements that Hamilton produced during the 1930s. They are thin, well-finished movements that wind and set through a conventional crown, with a small subseconds hand running off the movement's third wheel train. Both versions are reliable and serviceable when properly maintained, though parts availability has become more limited as these movements age.
