About the Dateline A-280
The Dateline A-280 appeared in only one catalog year, 1966, making it one of the shorter-lived references in the Dateline family. It runs on Hamilton's caliber 694A, a 17-jewel automatic with a date complication that displays through a window at 3 o'clock. The case is 14K yellow gold with a round profile and swept lugs, and the dial pairs a silver finish with applied bar markers and a sweep seconds hand. The Dateline family sits within Hamilton's broader push into automatic dress watches during the mid-1960s, and the A-280 represents the gold-cased tier of that lineup.
Applied bar markers on a silver dial are prone to separation or developing small gaps at their bases over decades, so a close look at the dial surface is worth the time. The date complication adds visual interest at 3 o'clock, and on a well-preserved example the contrast between the silver dial and gold markers still reads cleanly. Original retail in 1966 was $175, which positioned this firmly in Hamilton's upper-tier dress watch range.

What to Look For
| Dial | Look closely at the applied bar markers for any that have separated, shifted, or developed gaps at their bases. Check for spotting, discoloration, or refinishing around the date window at 3 o'clock, which is a common area for moisture damage on older automatics. |
| Crystal | Check for chips, deep scratches, or crazing. Replacement crystals for round gold dress watches are generally available, but confirm the fit is correct before purchasing. |
| Movement | The 694A is an automatic and should wind from normal wrist movement, but oil dries out on any movement of this age. If it runs inconsistently or stops when left on the wrist, dried lubricants are the likely cause. A service is worth budgeting for. Also note that the spring-loaded parts in the date complication are small and easy to lose during disassembly, so this movement rewards a careful watchmaker. |
| Case | 14K yellow gold cases can show wear at the lug tips and case edges, which is expected. Check for deep gouges or signs that the case has been polished aggressively, which can round off the lugs and soften the original profile. Case backs can be tricky to open on vintage Hamiltons, so avoid prying marks around the case back edge. |
| Crown | The crown should seat firmly and turn smoothly in both the winding and date-setting positions. A sticky or loose crown can indicate worn stem threads or a compromised setting mechanism, and on a date-complication movement that adds some complexity to the repair. |
The Movement
The caliber 694A is a 17-jewel automatic movement, meaning it winds itself through an oscillating rotor that spins with normal wrist motion. It includes a date complication, with the mechanism driving the date wheel displaying through the window at 3 o'clock on the dial. Hamilton used the 694A across several of its Dateline references during this period, and it is a capable movement when properly serviced.
