About the Accumatic VIII-B
Made from 1961 through 1963, the Accumatic VIII-B runs on either the caliber 679 or caliber 689, both 17-jewel automatic movements, housed in a stainless steel case measuring 12mm thick with an 18mm lug width. The VIII-B is closely related to the Accumatic VIII, sharing the same basic configuration but offering the bracelet availability that distinguishes the B variant. As part of the broader Accumatic family, it represents Hamilton's push into reliable everyday automatic watches during the early 1960s. The dial comes in black or white, with embossed silver numerals at the 6 and 12 positions, embossed silver markers, luminous material, and a pearled track around the chapter ring.
Finding one with an honest dial is the first thing to check. The embossed numerals and markers hold up well, but the luminous material degrades over decades and can become patchy or discolored in ways that are easy to overlook in photos. Both the black and white dial versions show up with some regularity, and either is a solid candidate for a daily wearer once properly serviced.
From the Catalog
Hamilton's 1961 catalog described the Accumatic VIII-B as having a stainless steel case with white embossed numerals and luminous markers on a black or white dial featuring a pearled track. It retailed for $65.00 on bracelet, or $59.50 on strap.

What to Look For
| Dial | Look closely at the luminous material on the markers. After 60-plus years, it often turns creamy, flakes, or goes uneven. The embossed numerals and markers should be crisp and evenly raised. On the black dial version, check for fading or separation at the edges. On white dials, look for yellowing or spotting that photos tend to hide. |
| Crystal | These take a standard acrylic crystal. Deep scratches are common after decades of wear. A replacement crystal is straightforward, but confirm the correct profile before sourcing one. |
| Movement | The caliber 679 and 689 are automatics and should wind reliably from wrist motion. If the watch needs to be hand-wound repeatedly just to keep running, dried oil is likely creating enough friction to interfere with the rotor or gear train. A watch that won't sustain itself on the wrist is telling you it needs a service. |
| Case | Stainless steel cases from this era wear well, but check the lugs for thinning if the watch has been polished. The case back can be tricky to open on these, and improper tools leave marks. Look at the case back edge for dings or slippage scars that indicate someone pried it open without the right equipment. |
| Crown | Check that the crown threads smoothly and seats fully. Two-piece stems were common on movements of this type, and a crown that wobbles or has any play laterally may indicate a stem that has already been stressed or broken at the joint. |
The Movement
The Accumatic VIII-B was fitted with either the caliber 679 or the caliber 689, depending on production timing. Both are 17-jewel automatic movements that wind from wrist motion via a rotating rotor, with no need for manual winding during regular wear. They are solid, serviceable movements, though the reassembly process requires careful alignment of the gear train, and a watchmaker who knows these calibers will get better results than one working from them cold.
