1941 Omega Dress Watch (Ref. CK 2242) 'Cal. 30SCT2'

The cal. 30T2 is a time-only manual wind movement that Omega created in 1939, and became a large benefactor for building Omega's early reputation of making accurate and quality timepieces. The cal. 30T2 is essentially a robust but simple base movement that is very versatile in its adaptability, in fact, variations of the cal. 30T2 was produced until 1963. This legendary movement wasn't only for civilian use either, as the British military issued a massive contract with Omega to produce chronometer-rated timepieces for their soldiers that all housed a modified cal. 30T2 movement.

As a modular base caliber, Omega was able to modify the cal. 30T2 to fit the specification needs for a myriad of different timepieces. One example of which is presented here, the ref. CK 2242, which features the cal. 30SCT2, a center second's variation of the modular movement (hence the SC in the caliber name), and at the time was a celebrated enhancement within watchmaking.
