Notes

Ref. CK 2998 was launched in 1959, and was the successor to the Broad Arrow, reference CK 2915. This reference differed from its predecessor in that the Broad Arrow hands were replaced with alpha hands, and the steel bezel with one with a black insert. There were two generations of this reference; the first with large dot chronograph hand, the second with baton chronograph hand. This reference is called the ?pre-moon? by collectors. Cal. 321 with column wheel, was created in 1946. It was formerly called ?27 CHRO C12 T2? and was used on first generation ?moon watches?. The caliber was replaced in 1968 with cam-caliber 861
