Comments about the data

1975-1983, 342123
due to low profile often used as base for modules with additional functions
In the base movement a section opposite to the stem was left free (Fig.4), into which the gear of the automatic module extends. So despite the service friendly modular design the total height could be kept low.

Example, year: signature; shock device
1-4) ca. 1980: Juvenia Mfg Swiss 11511, 17 Jewels - Patented; Incabloc
(Juvenia 11511, without second)
5-6) 1982: Mido, Swiss, A/H 28800, 21 Jewels - Patented; Incabloc
(Mido 12892)
