The place for discussing 1930-1985 Heuer wristwatches, chronographs and dash-mounted timepieces. Online since May 2003.
The Reference 1158 Carrera (18 karat gold) had a relatively long production life, first seen with the 174xxx cases and being produced in several batches, ending in 394xxx.
So we see them with the Calibre 11 movement and the Calibre 12 movement.
As Mark points out, if we have the serial number, we can probably determine which movement would have been in the watch when it left the factory.
: Would appreciate if anyone can help me. Did the 1158 come with both
: the calibre 11 & calibre 12 and if so when did the change
: happen? It seems most of the watches have a Calibre 12 movement
: so wanted to check if the watch I am looking at is genuine given
: it has the calibre 11 movement. Any help appreciated
