Dateline A-689
1972–1976 · 14k Gold Electroplate / Stainless Steel
About the Dateline A-689
Made from 1972 through 1976, the Dateline A-689 is part of Hamilton's Dateline family, a line built around automatic movements with date complications. It runs on the caliber 694A and comes in a 14k Gold Electroplate case with a stainless steel back. The Dateline family has its own dedicated guide for deeper context, but this particular model appeared across multiple catalog years with at least two distinct dial configurations: a blue dial at introduction and a gilt dial in later production.
Finding one with an honest dial is the first thing to sort out. The blue dial examples from the early 1970s can show fading or spotting near the edges, while the gilt dial versions tend to hold up more consistently. Either way, confirm which dial you're actually looking at before assuming it matches a specific catalog year, since these watches moved through several configurations over the production run.
From the Catalog
Hamilton offered the A-689 on a strap at $100.00 and on a bracelet at $119.95 at launch in 1972, with the blue dial version positioned as an accessible entry into the automatic date category. By 1975 the gilt dial configuration carried a retail price of $350.00, reflecting both inflation and a shift toward a more formal presentation.

What to Look For
| Dial | Check for even color across the full surface. Blue dials from the early production years can fade unevenly, especially near the edges or under the crystal lip. On gilt dial examples, look for spotting or silvering where the finish has separated or flaked away. Hour markers should be crisp and evenly seated. |
| Crystal | Inspect for deep scratches or crazing. Replacement crystals for this case profile can be hard to match precisely, so a heavily damaged original is worth factoring into your evaluation. |
| Movement | Ask about service history. Lubricants in movements this age dry out over time, and a 694A that hasn't been serviced recently may run erratically or stop altogether. The date complication adds small spring-loaded components that are easy to lose during a careless service, so knowing who worked on it matters. |
| Case | Gold electroplate wears through at the lugs and crown area first. Look at those spots closely in good light. A case that's been polished repeatedly can show thin or missing plating. The stainless steel back is more durable, but check for corrosion around the seam. |
| Crown | The crown on a 694A-based watch handles both time-setting and date quick-set functions. Work it through both positions and confirm the date advances cleanly. A crown that slips or feels loose may indicate a worn stem or worn crown threads. |
The Movement
The caliber 694A is an automatic movement with a date complication. It winds itself through a rotor that captures energy from wrist motion, so it doesn't need manual winding in normal daily wear. With solid watchmaker care, it runs reliably, but the date mechanism adds a layer of complexity that makes proper servicing by someone familiar with the caliber worth seeking out.
