The Eterna Calibre 1432 is a clean, elegant manual‑wind movement from the golden era of Swiss watchmaking, beloved today by collectors and hobbyist watchmakers for its simple architecture and reliability.
Overview
It is a manual‑winding movement, not automatic, so it needs to be wound daily via the crown.
The 1432 was typically used in very thin dress watches, making it a classic “dress calibre”.
This movement is known for good hand‑finishing and solid construction, typical of mid‑20th century Swiss workmanship.
It was often produced in different versions (e.g., 1432 U for unwound or special configurations), so checking the movement number is important for parts and service.
For Hobbyist Watchmakers
Its layout is straightforward: minimal bridges, no automatic module, and easy access to the barrel and escapement.
The movement is well documented in vintage watchmaker’s literature, making it a good candidate for beginners learning manual‑wind servicing.
The balance is usually mounted with a shock‑proof device (like Incabloc or similar), which simplifies cleaning and re‑assembly.
When disassembling, note the specific drop‑lever and yoke configuration, as some variants have subtle differences in the setting mechanism.
