The ETA 1210 watch movement, designed for both the European and U.S.A markets, showcases distinct technical characteristics. The European version features bridges that are not bevelled, a flat hairspring, a gold lever, and Super-Shock-Resist. Conversely, the U.S.A variant presents bridges that are bevelled, a Breguet hairspring, and a ratchet wheel mounted with a washer. The movement encompasses a manual wind mechanism, a sub second function, and a date complication.
