Comments about the data

Remarks
open face calibre
bimetallic screw balance, Breguet hairspring
lever with hidden pallets and counter weight (moustache lever)
barrel with Geneva stopwork
As the Landeron signature is overwritten, the ebauche came likely from Landeron, and was finished by Straub (Alpina). However, this is not sure, and therefore this calibre is listed preliminary as both, Alpina and Landeron.

Example, year: signature; shock device
ca. 1895: Albert Mayer, Chemnitz - 50862
under 3/4 plate: 50862, Hahn Landeron (overwritten, Fig.3), trademark J. Straub (Fig.4)
