Accumatic VI
1959–1960 · 10k Rolled Gold Plate / Stainless Steel · Automatic
About the Accumatic VI
Made from 1959 through 1960, the Accumatic VI runs on Hamilton's caliber 672, a 17-jewel automatic that was the workhorse of the early Accumatic lineup. The case is 10K yellow Rolled Gold Plate with a stainless steel back, round in shape, and offered from the factory with either a black or white dial. The Accumatic VI is part of Hamilton's Accumatic family, and sits alongside closely related models including the VI-B, the Accumatic VIII, and the VIII-B. What sets the VI apart visually is the dial treatment: embossed gold numerals at the even hours, luminous markers, and a pearled track that gives the dial a dressy, textured look.
Condition on the dial is where to spend the most attention with this one. The embossed gold numerals and luminous markers can show age, and the pearled track is a delicate detail that doesn't always survive rough handling or amateur service attempts. Both the black and white dial variants turn up with some regularity, and neither is dramatically harder to find than the other, though the black dial tends to show lume aging more visibly.
From the Catalog
Hamilton listed the Accumatic VI in 1959 as a waterproofed automatic available in white or black dial, priced at $79.50 on bracelet or $69.50 on strap. The catalog called out the embossed yellow numerals, luminous markers, and pearled track as the defining dial features.

What to Look For
| Dial | Check the embossed gold numerals and luminous markers closely. The pearled track is particularly vulnerable to damage from improper cleaning or case work. Look for separation, discoloration, or loss of the track detail. Both black and white dials are correct for this model. |
| Crystal | This model would have left the factory with an acrylic crystal. Look for deep scratches or crazing, which are common after sixty-plus years. A quality replacement crystal is inexpensive and makes a real difference in how the dial presents. |
| Movement | The caliber 672 is a capable automatic, but dried oil is a real concern on any example that has sat unserviced for years. If the watch runs inconsistently or stops with gentle movement changes, assume it needs a full service before daily wear. |
| Case | The 10K yellow RGP case will show wear through to the base metal on high-contact surfaces like the lugs and caseback edges. That's normal and expected on a watch this age, but heavy wear-through affects both appearance and value. |
| Crown | The caseback on this model uses a threaded ring that can be a challenge to open, since the slots are small and don't always play nicely with standard case wrenches. Signs of marring around the caseback edge may indicate previous amateur opening attempts. Also worth noting: despite Hamilton's original waterproof rating, vintage watches of this era should not be exposed to water. |
The Movement
The caliber 672 is a 17-jewel automatic movement that Hamilton used throughout the early Accumatic years. It winds via a rotor that swings with wrist motion, though it can also be wound manually at the crown. The 672 is a reliable, serviceable movement with a good track record, but like any automatic from this era, it rewards regular lubrication to keep it running well.
