ETA 2483

Probable

One of the calibers behind the vintage Tudor Submariner. Recorded with a thin specification because the reliable published data for it is thin: the specification fields left empty here are unknowns, not omissions.

Architecture

Automatic with centre seconds and date, from the ETA/Eterna family used across the Swiss industry in the 1960s and 1970s.

Service practice

A widely used industry ébauche, so service parts have circulated for sixty years and a rebuilt example may contain components from other watches entirely. That is normal for the caliber and is an originality observation rather than an authenticity one.
