Caravelle (Bulova) movement 11UHACB - info or specs ?


I just purchased a lovely 1969 or 1970 (I believe, but need to check) Caravelle Automatic, NOS, gold plated (see photo) that I should receive this week.
Does anyone know what is the correspondance of the caliber 11UHACB (see photo) ? I believe it' s an AS of some sort.
Unfortunately I find references on the web to this movement as well as spare parts websites, but none have any info or technical specs. It is not, strangely, on the RANFFT archives like many other Bulova movements although it should be a known Bulova movement.
Any info would be appreciated, thanks !!

11UHACB is a variant of Bulova calibers 11AOACB. It wasn't sold in the U.S.

Same pull-out crown for date quick set

These are good movts. They were the last of the decent quality automatics, soon to be buried by the quartz crisis in the 70's. If memory serves, they are AS based, but Bulova modded them a bit more than usual.
