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, as in the present lot, with
baton chronograph hand.
This reference is sometimes known as
the “pre-moon” by collectors.

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
