About the Dateline A-681
Made from 1968 through 1971, the Dateline A-681 is part of Hamilton's Dateline family, a line built around automatic movements with date complications. It runs on the caliber 694A, a 17-jewel automatic, and comes in a 10K yellow Rolled Gold Plate case with a circular profile. The silver dial carries applied gold numerals and embossed gold markers, giving it a clean but substantive look for its era.
Applied gold numerals and embossed markers hold up well over time, but check closely for any separation or corrosion at the edges where metal meets dial surface. The Rolled Gold Plate case can show wear through to the base metal at high-contact areas like lugs and case back edges, so condition varies considerably from example to example. Finding one with a solid dial and honest case wear makes for a very wearable vintage automatic at a reasonable entry point.
From the Catalog
Hamilton offered the A-681 in 1968 at $89.50 on a strap and $99.50 on a bracelet, positioning it as an accessible automatic with date in the Dateline lineup.

What to Look For
| Dial | Look carefully at the applied gold numerals and embossed markers. Any separation, corrosion halos, or moisture staining under the crystal should factor into your assessment. Silver dials from this period can develop an attractive patina, but uneven spotting or water damage is a different story. |
| Crystal | Check for deep scratches or crazing. Replacement crystals are available for most circular cases from this era, but confirming the correct diameter before purchasing saves headaches. |
| Movement | The 694A is an automatic with a date complication, and the small spring-loaded components in the date mechanism are easy to lose during service. Ask whether it has been recently serviced, and watch for erratic timekeeping or a date that hesitates or fails to advance cleanly at midnight. |
| Case | Rolled gold plate wears through with time, especially at the lugs and case back. Look for any areas where the gold layer has worn away to reveal the base metal beneath. Light wear is expected and honest; deep wear through on the lugs affects both look and long-term durability. |
| Crown | Work the crown through all its positions, winding and date-setting. It should move smoothly and seat firmly when pushed back in. A crown that feels loose or fails to engage the movement cleanly may indicate a worn stem or damaged setting mechanism. |
The Movement
The caliber 694A is a 17-jewel automatic movement that Hamilton used across several Dateline models in this period. It winds via a bidirectional rotor, so normal wear keeps it running without hand-winding, and it drives a date complication that advances through a gear train at midnight. It's a capable and reasonably robust movement, though like any watch of this age, dried lubricants can create enough friction to stop it or cause erratic rate, so a fresh service matters.
