Have a look at the tiny triangle stamped into the top right lug (when looking at the watch backcase ). This is an indication that its an 11i movement. The factory had already recognised some of the mis-givings of the initial date change mechanism on the Cal.11's and created a "quick fix" for the remaining Cal.11 movements. The later Cal.12's which were in production in 1971 didn't suffer the same issues.

: I can't place it in Reference Table? According to the Reference
: table all Cal 11s should have 3,6,9,12 on the hour recorder?
