About the Dateline A-477
Made from 1969 through 1970, the Dateline A-477 is part of Hamilton's Dateline family, a line of automatic date watches that brought practical everyday functionality to Hamilton's mid-century catalog. It runs on the caliber 694A, a 17-jewel automatic with a date complication, housed in a 10K yellow Gold Filled round case. The Dateline A-477 was produced for only one year, appearing in a single catalog year before being replaced or discontinued.
Finding one in solid condition means paying close attention to the Gold Filled case, which shows wear at the lugs and high points before anywhere else. The 694A movement is a capable automatic, but at this age the service history matters more than it might on a simpler movement, since the date complication adds parts that need proper lubrication to function reliably.
From the Catalog
Hamilton listed the A-477 with a stainless steel case at an original price of $89.50, and described it as both shock-resistant and weatherproof, reflecting the practical, durable positioning Hamilton used for the Dateline line.

What to Look For
| Dial | Check the dial carefully under good light for spotting, separation at the indices, or refinishing. A redone dial will look too clean and uniform, and the indices may sit unevenly or show adhesive residue around their bases. |
| Crystal | Inspect the crystal for cracks and deep scratches. Replacement crystals for this generation of round Hamilton can be sourced, but confirm the fit is correct before buying. |
| Movement | Ask about service history. The date complication in the 694A relies on small spring-loaded parts that are easy to lose during service, and dried lubricants at this age can create enough friction to stop the movement or cause erratic timekeeping. Confirm the date changes cleanly and advances fully at midnight. |
| Case | The 10K gold-filled case will show wear through to the base metal on the lugs and high points if it has lived a normal life. Light wear is expected and honest. Heavy polishing that rounds the lug edges is more of a concern than honest patina. |
| Crown | Work the crown through winding and date-setting positions. It should move cleanly between functions without slipping or feeling gritty. A sticky or difficult crown often points to a dried gasket or a stem that needs attention. |
The Movement
The caliber 694A is a 17-jewel automatic with a date display, and it represents Hamilton's reliable workhorse design for the late 1960s. The rotor winds the mainspring in both directions, which makes it efficient for everyday wear, and the date function advances via a quick-set mechanism driven off the movement's gear train. It is a well-designed movement, but the date complication involves small components that require careful handling during service.
