Calibre 146 — compact hand-wound for dress watches

In brief

Dress cases of the period were smaller and more discreet than the ones Zenith used for its tool and precision watches. The 146 is the narrow hand-wound calibre made to sit inside them.

Short history

For all the competition and precision movements that made Zenith's name, the company ran a parallel line of smaller, simpler hand-wound calibres — intended for everyday dress watches rather than for the chronometry trials. The 146 comes from that quieter side of mid-century production.
