Glycine Manufacture Movements
Glycine manufactured its own movements from 1914 until it has been acquired by ASUAG in 1942. The company has sourced movements for other brands also, so as A.LeCoultre ( Cal 18 ) and Bulova (cal 50 ). Below is a chart from 1942 showing the manufacture movements along with the automatic module of Eugene Meylan.
Even though the ASUAG movements started to dominate the whole manufacture, some models from the '50s and '60s still have the in-house calibers. I believe they were stock movements or still being produced within ASUAG.
Serial Numbers

Glycine Manufacture Movements
Airman shared the numbering system with other models. Glycine serial numbers have changed several times and is not consecutive through ownership changes. Some decades have two different numbering systems running simultaneously. We are able to date most timepieces after 1952 accurately, however pre - '40s is tricky . Thankfully we have some marks and rules applying to help us dating earlier timepieces so as: poincon de maitre type, dial marks, hallmarks of precious metal, case-makers mark, government regulations for imported/exported timepieces and related dial & movement marks...
