23.4

OMEGA’s 23.4 was a compact manually wound movement produced primarily during the 1930s. Measuring approximately 23.4mm in diameter, it was commonly housed in smaller round cases and reflected the practical, well-proportioned watchmaking for which OMEGA was known during the period.

Watches fitted with the 23.4 often feature simple small-seconds layouts, Arabic numerals, railway minute tracks, and two-tone dials — details strongly associated with pre-war watch design. Despite their modest dimensions, these watches are notable for their balanced proportions and classic character, making them a distinctive expression of 1930s OMEGA.
