About the Dateline A-592
Made from 1972 through 1974, the Dateline A-592 is a stainless steel automatic from Hamilton's Dateline family, powered by the caliber 694A. The Dateline line was Hamilton's answer to the growing demand for date-display automatics in the early 1970s, and the A-592 represents one of the more visually striking entries in that group, finished with an orange dial. It measures 35mm in length and 11mm thick, a proportion that reads as substantial without being oversized for its era.
Orange dials from this period are prone to fading unevenly, so color consistency across the surface is worth examining closely before buying. The applied indices are another thing to check carefully, since any that have separated or shifted affect both the look and the resale value considerably. Finding a well-preserved example with a clean, consistent dial is genuinely satisfying given how much character this colorway carries.
From the Catalog
Hamilton listed the A-592 in stainless steel with an orange dial, offered on a strap at $110.00 or on a bracelet at $119.95, as part of the Quick Change II case series.

What to Look For
| Dial | Orange dials can fade or develop uneven patina over fifty-plus years. Look for consistent color across the full surface, and inspect the applied indices to confirm all are flat, secure, and aligned. Any that have separated, shifted, or come loose are difficult to address without professional help. |
| Crystal | Check for deep scratches or chips. Replacement crystals for watches from this period are available, but fitting the correct profile matters for both appearance and water resistance. |
| Movement | Lubricants dry out over decades, and a movement this age that hasn't been recently serviced may stop or run erratically. Ask about service history before buying. The date complication in the 694A relies on small spring-loaded parts, and those are among the first things to cause problems when a service is overdue. |
| Case | The hidden lug design on this model gives it a clean profile, but inspect the lug area carefully for wear or any signs of prior strap damage. Stainless steel cases from this era hold up well, but look for any deep scratches or dings around the case edges. |
| Crown | Operate the crown through all positions: winding, date setting, and time setting. It should move smoothly and seat firmly when pushed back in. A crown that feels loose or difficult to seat can indicate a worn stem or worn crown tube. |
The Movement
The caliber 694A is a Swiss-made automatic with a date complication, running at 17 jewels. It winds automatically through normal wrist movement and can also be wound manually by the crown. The date wheel advances via a spring-loaded mechanism that is reliable when properly lubricated but can become sluggish or erratic as oils age.
