About the Dateline S-577
Made from 1968 through 1969, the Dateline S-577 is part of Hamilton's Dateline family, a line built around the practical appeal of an integrated date display. It runs on the caliber 674, a 17-jewel manual wind movement, housed in a stainless steel round case with a silver textured dial, raised gold stick markers, and a date window at 3 o'clock. The sweep seconds hand give it a clean, purposeful look that was very much in step with late-1960s American watch design.
Finding one in solid shape takes some patience. The silver dial with its textured center is prone to showing age at the edges, and the raised markers can come loose or tarnish if a watch has spent time in damp conditions.
From the Catalog
Hamilton's 1968 catalog listed the S-577 simply as a calendar watch in a stainless steel case at $69.50, with a note that the waterproof and dustproof rating applied only with seals intact, a practical caveat that reflected how seriously Hamilton took its weatherproofing claims at the time.

What to Look For
| Dial | Look closely at the textured center for discoloration or uneven aging. Check that the raised gold stick markers are all present and sitting flush. The date window should have a clean edge with no moisture damage or fogging visible beneath. |
| Crystal | Check for deep scratches or chips around the edges. A cloudy or heavily scratched crystal is replaceable, but confirm the fit is tight with no gaps that suggest a prior replacement went wrong. |
| Movement | The 674 is a manual wind, so wind it fully before evaluating the rate. Dried lubricants on a movement this age create enough friction to stop it entirely, so erratic timekeeping or a watch that winds stiffly is a sign it needs a full service. |
| Case | That style of lug hides wear and small dings well, so take a close look from multiple angles. Check the caseback for tool marks from prior openings, which can indicate a rough service history. |
| Crown | The S-577 was marketed with weatherproof seals, but no vintage watch should be trusted near water at this point regardless of original ratings. The crown should pull out smoothly to the date-set and hand-set positions without wobble or resistance. |
The Movement
The caliber 674 is a 17-jewel manual wind movement that Hamilton used across several of its date-display models in the late 1960s. It is a straightforward, reliable workhorse of a caliber, not flashy but well-built and capable of solid timekeeping when properly serviced. Because it incorporates a date mechanism, there are more small parts involved than in a simple time-only movement, and those calendar components, particularly the small springs, deserve careful attention during any service.
