Omega launched the 27 CHRO C12 project jointly with Lemania in 1942, which led to the development of the caliber 321. The CK 2451 was introduced in 1946, and utilized the 27 CHRO C12 T1 and 27 CHRO C12 T2 movement, renamed as the 321. The 27 refers to the diameter of the movement in millimeters, ‘CHRO’ to the fact that it has a chronometer, and C12 to refer to the 12-hour counter. This co-developed project began in 1942. The 321 ended its initial production run in 1968.

Omega provides sparse notes on the CK 2451, only that it has a dial with inside tachymeter scale (though that is not the case for the CK 2451 dials in the Omega Cropped 3-6-9 movement number project).
