OMEGA 33.3

The OMEGA caliber 33.3 is a manual-winding chronograph introduced in 1894 as one of the brand's earliest in-house movements. It belongs to the 33 caliber family and was produced under the reference "cal. 33.3" in contemporary Omega nomenclature. The movement remains discontinued, representing a historical milestone in Omega's manufacture of chronograph calibers rather than current production.
