 Fig. 1  Fig. 2  Fig. 3  Fig. 4 | Landeron 19''' (=Alpina 19'''H6.8) Features stem wind and pin set sub second Data 19''', Dm= 42.6mm, Do= 43.8mm H= 6.8mm 15 jewels f = 18000 A/h 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) © E. Preuß  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. |
