About the Dateline A-580
Made from 1965 through 1971, the Dateline A-580 is a cushion-case automatic in stainless steel, powered by Hamilton's caliber 694A with a date complication. The Dateline family was Hamilton's core offering for calendar automatics during the mid-to-late 1960s, and the A-580 represents the stainless steel, everyday-wear end of that lineup. The silver dial carries raised gold markers and a date window, with a sweep seconds hand giving it a clean, uncluttered read.
Cushion cases from this era often show wear on the lugs and case edges, so condition of the stainless steel is worth examining closely before buying. A known dial variant exists with hour markers featuring black inserts, which presents differently than the all-silver version and is worth identifying if originality matters to you. Either way, the 694A inside is a capable movement when properly serviced, and a clean example of the A-580 wears well for daily use.
From the Catalog
Hamilton marketed the A-580 simply as a calendar model in a stainless steel case, priced at $79.50 in 1965. The pitch was practical rather than flashy, which suits the watch well.

What to Look For
| Dial | Look for spotting, discoloration around the date window, and any signs of refinishing. The raised gold markers should be intact and sitting level. The black insert variant exists, so confirm which dial you have if originality matters. |
| Crystal | Check for deep scratches or crazing. Replacement crystals for cushion-case models can be harder to source than standard round ones, so a damaged crystal is worth factoring into your offer. |
| Movement | The 694A is an automatic and should wind from wrist motion, but oil dries out on movements this age and can create enough friction to stop the watch even if it appears to be running. A service is likely needed if it hasn't been done recently. The date complication has small spring-loaded components that are easy to lose during service, so ask about the work history. |
| Case | The cushion shape means the case edges and lug tips take wear from everyday use. Look at those areas under good light. Case backs on models like this can be tricky to open without the right tools, so prying marks around the case back edge are a red flag for amateur service attempts. |
| Crown | Test the crown in both the winding and date-setting positions. It should feel positive and crisp. A loose or wobbly crown can indicate a worn stem or damaged crown tube, and either requires attention during service. |
The Movement
The caliber 694A is a 17-jewel automatic movement made in Hamilton's Swiss production era. It winds from wrist motion via a rotor, runs the sweep seconds hand directly off the gear train, and drives the date complication through a date wheel that advances at midnight. It's a solid, serviceable movement with a good track record, though like any automatic from this period it benefits from fresh lubrication to run at its best.
