1968–1971 · 14k Solid Yellow Gold · Automatic
About the Dateline A-281B
The Dateline A-281B was produced from 1968 through 1971, part of Hamilton's Dateline family of date-displaying automatics that brought practical functionality into dress watch territory. It runs on the caliber 694A, a 17-jewel automatic, and comes in a 14K yellow gold round case with a silver dial and applied gold markers, no numerals. The sweep seconds hand makes the automatic movement immediately visible at a glance.
Applied gold markers on a clean silver dial with no numeral clutter give this watch a refined, minimal character that holds up well when the dial is in good shape. Condition of the applied markers is worth close attention on any example, as they can pull away from the dial, tarnish, or show corrosion at the base over decades. The 14K gold case means weight and warmth in hand that Gold Filled examples simply cannot match.
From the Catalog
Hamilton positioned the Dateline series as dress automatics with the added utility of a date display, and the A-281B in 14K gold represented the higher end of that offering. Original pricing reflected the solid gold case, placing it well above the gold-filled variants in the same family.

What to Look For
| Dial | Look closely at each applied gold marker under good light. Check for separation at the edges, corrosion at the base where the marker meets the dial, or any markers that appear to have shifted. A clean silver dial should be even in finish with no spotting or haze. |
| Crystal | Inspect the crystal for chips, deep scratches, or crazing. If it appears to be a faceted style, know that finding a correct replacement is genuinely difficult, so condition matters more than usual here. |
| Movement | Ask about service history. The caliber 694A is an automatic with a date complication, and dried lubricants in a movement this age can create enough friction to stop it or cause erratic timekeeping. The date mechanism includes small spring-loaded parts that require careful handling during service. |
| Case | Confirm the case is solid 14K gold, not gold-filled. Check the lugs for wear or thinning, and look at the case back for evidence of forced opening, which can leave marks or damage the edge. Case backs on watches of this era can be snug and are sometimes pried incorrectly by previous owners. |
| Crown | Test the crown through all positions: winding, date setting, and time setting. It should click cleanly between positions and screw or push back in fully without resistance. A sticky or loose crown can indicate a worn stem or damaged crown tube. |
The Movement
The caliber 694A is a 17-jewel automatic movement from Hamilton's Swiss production era, featuring a date complication with sweep seconds. It winds via a rotor as the watch moves on the wrist, so it does not need daily hand-winding under normal wear. Like most automatics of this period, it benefits from a proper service to replace dried lubricants and inspect the date mechanism, which carries several small parts that are easy to lose if the movement is opened carelessly.
