Accumatic IX-B
1961–1962 · 10k Yellow Gold Filled / Stainless Steel · Automatic
About the Accumatic IX-B
Made from 1961 through 1962, the Accumatic IX-B is a round-cased automatic from Hamilton's Accumatic family, wearing a 10K yellow Gold Filled case with a stainless steel back. It runs on the caliber 679, a 17-jewel automatic movement, and shows the time with a sweep seconds hand on a silver dial with embossed gold numerals at 12 and embossed gold markers with luminous fill and a pearled minute track around the perimeter. The Accumatic line was Hamilton's answer to the growing demand for self-winding watches in the early 1960s, and the IX-B represents a clean, well-proportioned entry in that series.
The pearled track on the dial is a detail worth inspecting closely, as it can show wear or discoloration on examples that have been exposed to moisture or improper storage over the decades. The embossed gold numerals and markers have a subtle dimensional quality that photographs don't always capture well, so seeing one in person tends to be more rewarding than the listing photos suggest.
From the Catalog
Hamilton listed the IX-B in 1961 at $79.50 on strap, calling out the yellow embossed numerals, luminous markers, and pearled track as the defining dial features, along with the 10K yellow gold-filled case and stainless steel back. A bracelet version was also offered at $89.50.

What to Look For
| Dial | Look at the pearled minute track carefully under good light. Spotting or discoloration there is common on examples that have seen moisture. The embossed gold numeral at 12 and the luminous markers should be intact and even, with no separation or flaking. Lume that has gone dark or patchy is normal for a watch of this age, but missing or damaged markers affects both the look and the value. |
| Crystal | Check for deep scratches or crazing. A lightly scratched crystal can often be polished or replaced without drama, but a crazed or cracked one needs to go before moisture finds its way to the dial. |
| Movement | The caliber 679 is an automatic, and lubricants dry out over time. A watch that needs to be hand-wound repeatedly or stops when left on the wrist is showing signs of friction from dried oil, and a service is the right answer. Confirm the sweep seconds hand moves smoothly and consistently, not in fits and starts. |
| Case | The gold-filled case can show wear through to the base metal at the lugs and case edges, especially on watches that were worn regularly. Some honest wear is expected and acceptable. Check that the case back is present, fits correctly, and shows no signs of having been forced open with a blade. |
| Crown | Pull the crown gently and confirm the watch sets smoothly without grinding or slipping. A worn or damaged crown on a watch this age is not unusual, but replacing it requires the right part, and a stripped or cross-threaded crown is worth factoring into the price. |
The Movement
The caliber 679 is a 17-jewel automatic movement that Hamilton used across several of its early-1960s round-cased Accumatics. It winds itself from the motion of the wrist through a rotor system, so under normal wearing conditions it should stay running without needing manual intervention. It's a reliable movement when properly serviced, compact enough to sit comfortably in a dress-weight case.
