Notes
1954-1966 (family J93, J93/1)
ratchet on dial side, crown mechanism with rocker bar
only few made, soon replaced by variants of the J93/1
The official (only) version with 8 jewels is based on the 693.80 with an 8th jewel in the friction spring for the sweep second. The example with 12 jewels proves that the production wasn't straightly organised, and also parts of variants with more jewels were used.
