Accumatic VI-B
1961–1962 · 10k Rolled Gold Plate / Stainless Steel · Automatic
About the Accumatic VI-B
The Accumatic VI-B was produced from 1961 through 1962, placing it in the early run of Hamilton's Accumatic family of automatic watches. It runs on the caliber 689, a 17-jewel automatic movement, housed in a 10K yellow Rolled Gold Plate case with a stainless steel back. The dial comes in either black or white, with embossed gold numerals at the even-hour positions and embossed gold luminous markers rounding out the layout, all set against a pearled track. The sweep seconds hand completes the clean, legible look that made the Accumatic line popular with everyday wearers.
Embossed numerals and markers hold up better over time than printed ones, which is genuinely good news on a watch this age. The bigger concern on surviving examples is the case finish: Rolled Gold Plate wears through at the lugs and high points of the case, and condition varies considerably from one example to the next. Both the black and white dial versions turn up in roughly equal numbers, and either one cleaned up and running well is a satisfying find.
From the Catalog
Hamilton marketed the VI-B in 1961 with the option of a black or white dial, describing the embossed yellow numerals, luminous markers, and pearled track as the defining dial details. With a strap, the watch retailed for $69.50, while the bracelet version carried a higher price point.

What to Look For
| Dial | The embossed gold numerals and markers are durable, but look closely for separation or loss at any of the even-hour positions. The pearled track around the perimeter is a detail that often gets overlooked during past restorations and can show damage from careless cleaning. Check that the dial color is consistent across the surface with no fading or moisture spotting. |
| Crystal | Expect a plastic crystal on a watch of this era. Light scratches are normal and can often be polished out, but a deeply scratched or cracked crystal should be replaced before wear. Confirm it sits flush and sealed in the bezel. |
| Movement | The caliber 689 is an automatic and should keep itself wound from normal wrist motion. Dried oil is a real concern at this age. A watch that stops after a few hours on the wrist, or one that requires repeated hand-winding to keep going, is telling you it needs a service. |
| Case | The 10K yellow rolled gold plate will show wear on the lugs and case edges over time. This is normal and expected, but the degree of wear matters for value. Check that the stainless steel back is free of deep scratches or dents and that the case back threads or snaps cleanly without signs of past forced opening. |
| Crown | Pull the crown to the setting position and confirm it moves the hands smoothly without slipping or grinding. A worn or replaced crown is common on vintage Hamiltons and not a dealbreaker, but it should be the correct size and finish for the case. |
The Movement
The caliber 689 is a 17-jewel automatic movement made by Hamilton in the United States. It winds itself through a rotor that spins with wrist motion, so under normal wear it should stay wound without any help. It is a reliable workhorse of the Accumatic line, straightforward to service when the lubricants are fresh, but the wheel train alignment during reassembly requires patience and is one reason a proper service matters on these movements.
