Omega 265 Description
The Omega 265 is a historically significant manual-wind caliber, representing the formal renaming of the original 30T2 small-seconds movement in 1949. As the first of the 26x series, it was most commonly produced with 15 jewels. This robust 30mm workhorse powered a multitude of Omega’s classic dress watches in the early 1950s and is the foundation upon which the later 26x calibers were built.
