The Eterna Calibre 1462 is a compact, modestly jeweled manual‑winding movement from the 1950s–1960s, often used in small dress watches and occasionally in chronographs or calendar models. It is a solid, serviceable workhorse rather than a high‑complication engine, and it appeals most to vintage watch collectors and hobbyist watchmakers who appreciate Eterna’s sturdy, no‑frills Swiss engineering.
General overview
The Calibre 1462 is a manual‑winding movement, so it requires daily winding like a classic pocket watch.
It was commonly used in Eterna’s dress watches of the 1950s and 1960s, typically in 10–12 ligne (approx. 22–27 mm) cases.
Its design is straightforward: no hacking, no quick‑set date, and no power‑reserve indicator, making it simple to service and adjust.
Many examples are found in Eterna‑signed watches, but the movement also turned up in some third‑party brands and private‑label dress watches.
For hobbyists, it’s an accessible manual calibre to learn servicing, cleaning, and oiling on a relatively small, manageable 10–12 ligne platform.
