About the Essex (1940)
The Essex appeared in Hamilton's catalog in 1940 and remained in production through 1946, giving it a modest run among Hamilton's rectangular dress watch lineup. It runs on the caliber 980, a 17-jewel manual wind movement, and came in a 10K yellow gold-filled or 10K coral gold-filled case. The coral variant is the more visually distinctive of the two, pairing a coral gold-filled case with a coordinating coral finish dial and 18K applied gold numerals. That kind of intentional color matching between case metal and dial was a particular hallmark of Hamilton's late prewar dress watch designs.
Finding a coral-cased Essex in good shape takes some patience. The coral gold-fill plating is softer and more vulnerable to wear than standard yellow GF, and many examples show significant case wear or polishing that has rounded edges that were originally crisp. Dials on these watches can also show age spots or discoloration, so a clean original dial makes a meaningful difference in desirability.
From the Catalog
Hamilton listed the Essex at $45 in 1940, describing the coral variant specifically as a coordinated set: coral finish dial paired with 18K applied gold numerals to match the coral gold-filled case, a detail that shows how deliberately Hamilton approached the presentation of these dress pieces.

What to Look For
| Dial | Look closely for spotting, lifting at the edges, or discoloration around the applied gold numerals. The coral finish is fragile and does not respond well to moisture or cleaning attempts over the decades. An original, unrestored dial in solid condition is harder to find than the watches themselves. |
| Crystal | These take a flat or very slightly domed crystal. Make sure the crystal fits flush with no gaps and that there are no deep scratches obscuring the dial view underneath. |
| Movement | The caliber 980 mainspring has a strong tendency to weaken or set with age, and a tired mainspring will show up as poor power reserve even after a full wind. Ask whether the watch has been serviced, and if not, budget for a full service including mainspring replacement. |
| Case | Coral gold-fill cases need extra scrutiny. Check the high points on lugs and case edges for plating wear, and look for any signs of aggressive polishing that has softened the original lines. Case backs on rectangular Hamilton dress watches can be tricky to open, and a previous owner forcing one can leave marks or damage to the case back edge. |
| Crown | Check that the crown winds smoothly and sets the hands without slipping or grinding. A crown that feels loose or spins without resistance may indicate a worn or damaged winding mechanism inside. |
The Movement
The caliber 980 is a 17-jewel manual wind movement that Hamilton used across several of its rectangular dress watches from this era. It winds smoothly by hand and keeps solid time when properly serviced, though the escape wheel jewels on this caliber have a known tendency to loosen over time. A watchmaker opening one of these should check that seating carefully before reassembly.
