About the Auto Cal Reliance
Made from 1974 through 1976, the Auto Cal Reliance is part of Hamilton's Auto Cal family of self-winding watches, sharing its lineup with related models like the Patriot, Valiant, and Sovereign. The case is round and 10k yellow Gold Filled, with a white dial and applied indices. Depending on production year, the Reliance was fitted with one of three calibers: the 689, 694, or 822, reflecting the component availability and running changes typical of Hamilton's Swiss-era production during this period.
The white dial is generally the first thing to inspect on a Reliance. The lacquer-based printing means any cleaning attempt risks wiping the dial, so condition here matters more than it might on a more robustly finished dial. The integrated lug design gives the case a distinctive presence that sets it apart from the more conventional round sports watches of the era, and finding one with the original bracelet or a well-matched strap intact adds to the overall picture.
From the Catalog
Hamilton positioned the Reliance as part of its Quick Change II automatic lineup, listing it at $145.00 and emphasizing the 10k gold filled case as part of its value proposition in the Auto Cal range.

What to Look For
| Dial | Look closely at the white dial under good light. The printed finishing on these dials cannot be cleaned without risking damage to the text and markings. Any smearing, fading, or ghosting around the numerals or brand name is permanent. The applied indices should be seated flat with no separation or peeling at the edges. |
| Crystal | Check for deep scratches or crazing. More importantly, note that this case opens through the crystal rather than the case back. Look around the crystal edge for scratch marks or dents from previous attempts to pry open the wrong side. Those marks tell you something about how the watch was handled in the past. |
| Movement | Wind the watch fully and let it run for at least a few hours before trusting the timekeeping. With three possible calibers across the production run, confirm which movement is present. Any of the three is serviceable, but knowing what's inside helps set expectations for service cost and parts availability. |
| Case | The 10k yellow gold filled case should have a warm, even finish. Check the integrated lugs specifically, as gold fill wears first at high-contact points. Thin spots or brass showing through at the lug edges or crown area are worth factoring into the overall assessment. |
| Crown | Operate the crown through all positions and feel for slippage or roughness. The two-piece stem design used in this era is a known fragility point during service, so a crown that feels loose or uncertain is worth flagging before anything else gets opened up. |
The Movement
The Reliance could ship with the caliber 689, 694, or 822, all automatic movements from Hamilton's Swiss production period. The 689 and 694 are closely related, both self-winding with a rotor that winds in both directions, while the 822 is a higher-grade movement with a date complication. Jewel counts vary by caliber, but all three are robust daily-wear movements when properly serviced and well within the capability of a watchmaker familiar with Hamilton's Swiss-era calibers.
