In brief

Lift the caseback on a 343 and the eccentric chronometer regulator is the one visible difference from a 342. Underneath it, the series carries on unchanged: 17 jewels, 19,800 vph, 28.1 mm.

Short history

It dates to 1950, shortly after the 342, and belongs to the same 28.1 mm series that produced Omega's first automatic Seamaster.
