ETA 2512 is a compact, hand‑wound Swiss movement valued for its robustness, slim profile and long production span from the late 1950s into the 1970s. It was widely used in smaller dress watches, especially ladies’ pieces, and remains attractive today for restoration projects and vintage builds.
Technical overview
Manual‑wind movement with 17 jewels and Swiss lever escapement.
Frequency of 21,600 vibrations per hour, balancing durability and accuracy for everyday wear.
Diameter around 7¾ lignes (about 17.2 mm) with a slim height near 2.8–3.0 mm, ideal for small, elegant cases.
Power reserve typically quoted around 40–44 hours when fully wound.
Design features
Indirectly driven minute hand via the third wheel, freeing space for a larger balance and mainspring barrel; this supports better rate stability and longer running time.
Incabloc shock protection and a conventional index regulator, making regulation and basic service straightforward for most watchmakers.
Round movement layout with simple three‑hand time display and no date, keeping the construction clean and service-friendly.
Collecting and servicing
Commonly found in mid‑century Swiss brands and private‑label watches, often under alternative caliber designations from houses like Dugena or BM.
Spare parts can still be sourced through movement dealers and donor watches, although certain key components (like balances and staffs) are becoming scarcer as stocks age.
When properly serviced and adjusted, ETA 2512 can deliver performance comparable to many modern entry‑level mechanical calibers, making it a solid choice for vintage restorations.
