Accumatic VII
1959–1960 · 10k Rolled Gold Plate / Stainless Steel · Automatic
About the Accumatic VII
Made from 1959 through 1960, the Accumatic VII runs on Hamilton's caliber 672 automatic and comes in a 10K yellow Rolled Gold Plate case with a stainless steel back. It belongs to the Accumatic family, Hamilton's line of automatic wristwatches from that era, and sits in the middle of the range in terms of price and specification. The dial is white with embossed gold numerals at 3, 6, 9, and 12, luminous markers and dots, and a pearled minute track, a fairly dressy treatment for what was otherwise a straightforward everyday automatic. Hamilton marketed it as waterproof, which was a meaningful selling point in 1959.
Finding one in honest shape means paying close attention to the dial, where the embossed gold numerals and luminous markers can show age in very different ways, the lume in particular tends to discolor or flake on examples that have seen real use. The rolled gold case holds up reasonably well but can show wear-through at the lugs and high contact points, so it's worth examining those areas carefully under good light before buying.
From the Catalog
Hamilton listed the Accumatic VII at $85.00 on bracelet and $75.00 on strap in 1959, positioning it as a capable automatic with a dressy dial and waterproof case. The catalog copy emphasized the embossed yellow numerals, luminous markers and dots, and pearled track alongside the rolled gold plate construction.

What to Look For
| Dial | Look closely at the embossed gold numerals and luminous markers. Lume can discolor, flake, or shrink over time, and damaged or missing lume dots will affect both appearance and value. The pearled minute track should be clean and intact, chips or worn sections are hard to miss and harder to fix. |
| Crystal | These left the factory with acrylic crystals. Scratches are common and usually polishable, but deep gouges or crazing mean a replacement is needed. Make sure the crystal fits flush and shows no signs of separation at the edges. |
| Movement | If the watch has sat unserviced for years, dried oil is a real concern. Even a small amount of friction from degraded lubricants can be enough to stop the 672 entirely. A watch that runs inconsistently or stops after being set down is a sign it needs a full service before regular wear. |
| Case | The 10K rolled gold plate case can wear through at the lugs and on the case sides where it contacts the wrist and bracelet. Check those areas carefully. Some wear is expected and acceptable, but heavy wear-through that exposes the base metal will affect the overall presentation. |
| Crown | Despite the original waterproof rating, this watch should not be exposed to water. The seals are decades old and cannot be relied upon. Also note that manually winding the crown engages the rotor, so winding by hand feels different than on a conventional automatic, this is normal behavior for the 672, not a sign of a problem. |
The Movement
The caliber 672 is a 17-jewel automatic that Hamilton used across a number of Accumatic models in this period. It winds automatically via a bidirectional rotor as the watch moves on the wrist, and it can also be wound manually through the crown, though the crown engages the rotor directly when doing so, giving it a slightly different feel than other automatics. It's a dependable workhorse movement, well suited to everyday wear, and responds well to a proper service when lubricants are refreshed.
