Calibre 333 — eccentric regulator, the end of the 330 series

In brief

The last of the 30.1 mm bumpers gained something the three before it did not: an eccentric regulator for precision adjustment. Everything else runs to the series pattern — 17 jewels, 19,800 vph, 30.1 mm.

Short history

Around 1950 the 333 brought the 30.1 mm branch of the bumper family to a close. Its fine-adjustment improvement shows how hard Omega was pushing for accuracy in its automatics during those years.
