Dateline A-279
1966–1967 · 14k Solid Yellow Gold · Automatic
About the Dateline A-279
Made from 1966 through 1967, the Dateline A-279 is part of Hamilton's Dateline family, a broad line of automatic date watches that Hamilton offered throughout the 1960s in a wide range of case materials and configurations. This particular model wears a 14K yellow gold round case and runs on the caliber 694A, a 17-jewel automatic movement. The dial is silver with applied bar markers and a date window at 3 o'clock, with a sweep seconds hand completing the layout.
Finding one in solid 14K gold means case condition matters quite a bit here. Gold wears differently than Gold Filled or base metal, and while it won't corrode, it does show dents, dings, and polishing history more clearly over decades of wear. The applied bar markers are worth a close look too, since any that have separated or come loose from the dial will affect both its appearance and value.
From the Catalog
Hamilton listed the A-279 in 1966 at $175, describing it simply as a 14K yellow gold model. That price point placed it among Hamilton's more serious dress offerings for the period.

What to Look For
| Dial | Check the applied bar markers carefully. Any that have separated, shifted, or gone missing will be visible and are difficult to source replacements for. Look for even patina across the silver dial surface, and confirm the date window aperture is clean and the printing around it is crisp. |
| Crystal | Confirm the crystal is present and uncracked. On a watch this age, the original crystal has likely been replaced at some point. Replacement crystals for round vintage Hamiltons are usually available, but fit matters, so check for any gaps at the bezel edge. |
| Movement | The 694A is an automatic, so it should wind from wrist motion, but dried oil on a movement this age creates enough friction to stop it entirely. If it's running, check that it's keeping reasonable time. If it's sluggish or stopping, a service is the right call before wearing it regularly. The spring-loaded date complication parts are small and easy to lose, so service on these movements should go to someone familiar with them. |
| Case | In 14K yellow gold, look for dents or deep scratches that can't be polished out cleanly, as well as evidence of over-polishing that has softened the lug edges. Case backs on these can be stubborn to open, so if the caseback shows fresh tool marks, ask whether it was recently serviced. |
| Crown | Test the crown through all its positions. It should wind smoothly, set the date, and set the time without slipping. The weatherproof rating from the factory no longer applies to a watch this age, so treat it accordingly and keep it away from water. |
The Movement
The caliber 694A is a 17-jewel automatic movement from Hamilton's American production era. It winds from a rotor that spins with wrist motion, storing energy in the mainspring without any manual winding required under normal daily wear. The 694A also drives the date complication, advancing the date disc automatically at midnight.
