About the Auto Date Fletcher
Made from 1973 through 1974, the Auto Date Fletcher is a rectangular stainless steel watch built around Hamilton's caliber 631. It belongs to the Auto Date family, which paired automatic movements with quick-change date functions at a time when that combination was genuinely useful and not yet ubiquitous. The Fletcher's gray dial give it a quietly architectural look that reads as very early 1970s without being loud about it.
Gray dials from this era can fade unevenly or develop a patina that reads more beige than gray depending on storage conditions, so color consistency across the dial surface is worth a close look. Finding one with the original bracelet or a strap that suits the case proportions makes a real difference in how the watch wears.
From the Catalog
Hamilton listed the Fletcher in 1972 as a stainless steel Q/C II with a gray dial at $175.00, a price point that reflected the added complexity of the quick-change date function relative to simpler automatics in the lineup at the time.

What to Look For
| Dial | Check for even color across the full gray surface. Fading or discoloration often shows first near the edges or under where a crystal has separated from the dial. The applied indices can also pull away slightly at the tips over time, so look closely under good light for any that appear raised or misaligned. |
| Crystal | The Fletcher uses a flat crystal over a rectangular case, and chips or deep scratches at the corners are common after fifty years. A replacement crystal is usually straightforward, but confirm the case dimensions before sourcing one. |
| Movement | Have the watch serviced before relying on it. Dried oil creates enough friction to stop a vintage automatic even when the watch appears to be running, and a movement that starts and stops intermittently is a clear sign it needs attention. |
| Case | That area can accumulate wear differently than the main case body, and any polishing done there tends to soften the profile noticeably. Crisp lug edges are a good sign the case hasn't been over-polished. |
| Crown | Test the crown through all its positions. The quick-change date function should advance cleanly without grinding. If there's resistance or the date jumps inconsistently, that's a signal the movement needs service before further use. |
The Movement
The caliber 631 is a Swiss-made automatic with a quick-change date complication, which Hamilton designated Q/C II in its marketing materials. It's a compact movement built to fit rectangular and cushion-shaped cases while still offering the convenience of an instant-set date. Jewel count data isn't available for this specific reference, but the 631 is generally regarded as a reliable movement when properly serviced.
