Comments about the data

Remarks
jewel bearings for barrel
The automatic gear is integrated into the movement, instead of attaching it to a manual-wind calibre as usual.
Together with the indirectly driven minute this allows a rugged movement with relatively big balance and low profile.

family/generations:
1103: manual wind
1104: manual wind, date
1105,1145: automatic
1106,1146, 6146: automatic, date
6148: automatic, day date

Example, year: signature; shock device
ca. 1970: Lanco Rotor, 6148; Incabloc

Not for Sale!
The movements presented in this caliber finder are not for sale. This is only a data sheet for identification and evaluation of the movement calibre, as well as for approximate dating.
