About the Accumatic A-515
The Accumatic A-515 appeared in 1972, part of Hamilton's long-running Accumatic family of automatic watches. It runs on the caliber 689 and comes in a stainless steel round case with A striking bright orange dial. The Accumatic line was Hamilton's accessible automatic range, and the A-515 fits that tradition while standing out visually thanks to a dial color that was very much of its era.
That orange dial is both the A-515's biggest draw and its biggest vulnerability. The printing on these dials cannot be cleaned without damaging it, so condition matters enormously. Finding one with a clean, unfaded orange dial and intact printing is the real challenge, and when it comes together, this is a genuinely eye-catching watch from a period when Hamilton was pushing color in ways it rarely had before.
From the Catalog
Hamilton listed the A-515 simply as a stainless steel watch with an orange dial, priced at $95.00. The water resistant designation was part of the original spec, though like all vintage watches of this age, it should not be relied upon today.

What to Look For
| Dial | The orange dial is the heart of this watch, and it's fragile. Look for fading, flaking, or any sign that the dial has been cleaned or touched up. The printing does not survive cleaning, so any attempt to restore a dirty dial typically leaves it worse than before. The applied indices should be present and sitting flush, with no separation or gaps. |
| Crystal | Check for deep scratches or chips. A heavily scratched crystal is easy enough to replace, but make sure any replacement is correctly fitted and seated without gaps. |
| Movement | Dried oil in the caliber 689 creates enough friction to stop the watch even when it appears to wind and set normally. A watch that runs but loses time significantly has almost certainly gone unserviced too long. Ask when it was last serviced, and budget for a clean if the answer is unknown. |
| Case | Case backs on these can be stubborn to open, so look for tool marks around the edge of the case back, which can indicate previous work done carelessly. |
| Crown | Pull the crown gently through its positions and make sure it moves and sets smoothly. The two-piece stem design in this caliber can be damaged during movement removal, so a crown that feels loose or doesn't engage cleanly is worth flagging before purchase. |
The Movement
The caliber 689 is a self-winding automatic movement from Hamilton, reliable and straightforward in its construction. It winds through a bi-directional rotor and keeps decent time when properly serviced. Like all movements of this age, it needs fresh oil to run well, and a caliber 689 that hasn't been serviced in years will show it in timekeeping, even if it appears to run.
