Comments about the data

Remarks
AS 1687, 1688 are the base for calibre families from Doxa, Eberhard, Favre-Leuba, Girard-Perregaux, and Zodiac. It is unknown whether they were sold to anybody else. In current calibre registers they scarcely appear as AS calibres.

Example, year: signature; shock device
ca. 1960: KXF, Zodiac Ltd., Swiss, 17 Jewels; Incabloc
(Zodiac 61)

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.
