About the Dateline A-584
Made from 1966 through 1970, the Dateline A-584 is part of Hamilton's Dateline family, a line built around the practical addition of a date window on automatic movements. This model runs on the caliber 694A, a 17-jewel automatic, and comes in a stainless steel round case with a silver dial, embossed silver markers, and a sweep seconds hand. The date complication was the defining feature of the Dateline line, and the A-584 delivers it in a clean, no-frills package that held up well across its four-year run.
The silver dial with embossed markers is what makes a well-preserved A-584 worth finding. Embossed markers can wear or flatten over time, so getting close to the dial before buying matters. Case condition on stainless steel examples tends to hold up reasonably well, but the swept lugs on this model show polishing damage more obviously than flat lug designs, so look for crisp edges.
From the Catalog
Hamilton's 1966 catalog listed the A-584 simply as a stainless steel cased automatic with a silver and white dial, stick markers, and a date window, priced at $89.50. That price point put it in practical, everyday automatic territory for the period.

What to Look For
| Dial | Check the embossed silver markers closely. Embossing can flatten, fill with grime, or lose definition from improper cleaning. The date window should be clearly legible with no fogging or discoloration in the aperture. |
| Crystal | Confirm what crystal is currently fitted. If a period-correct or custom-cut crystal is in place, note that non-standard replacements can affect the finished look on a round case like this. |
| Movement | The 694A is an automatic and should wind from wrist motion. Oil dries out over decades, and when it does, friction builds enough to stop the watch or cause erratic timekeeping. A service is overdue on virtually any unserviced example at this point. Also note that the date complication involves small spring-loaded parts that are easy to lose during a service, so choose a watchmaker who knows what they're doing with this movement. |
| Case | The swept lugs are a defining part of this case's look. Over-polishing rounds them off and removes sharpness that's hard to restore. Check the lug tips and the transition from case to lug for signs of heavy buffing. Case backs can be stubborn to open without the right tools, so don't force it. |
| Crown | Make sure the crown threads smoothly and seats fully. A loose or stiff crown can indicate damage to the stem or threads. This watch was originally rated weatherproof, but no vintage watch should be trusted near water regardless of its original rating. |
The Movement
The caliber 694A is a 17-jewel automatic movement that winds from the natural motion of the wrist through a bidirectional rotor. It also drives the date complication, advancing the date display once per revolution of the hour wheel. It's a capable workhorse movement from this era, reliable when properly serviced, and found across several Hamilton models from the mid-1960s onward.
