- CH313813 from 1953, registering the compressor case by Ervin Piquerez,Bassecourt. This patent can be seen on the Glycine Compressor Automatic watches. Not invented but used by Glycine.

- CH149137 and CH149138 filed in 1930 and registered in 1931, the famous automatic module by Eugene Meylan, La Chaux de Fonds. The same inventions are transferred to Automatic EMSA company by Eugene Meylan with different patent numbers:CH157572 (1931) and CH157573 (1931).
This module was capable to be mounted on 8,75 lignes hand wind calibers and turn them into bumper automatic wristwatches.The first example of these bumpers have some patent appl.numbers on it which are not registered. Maybe the announcement and the prototype watch was manufactured while applied for the patent and later plans have changed.
The announcement of the patents with 5 digits are above, the watch can be seen also in the collection page with these numbers on it. Until I found it, I thought that its one of the unrelated patent numbers presentation on vintage watches which was a popular marketing trick in 1930's. The US patents mentioned on the module do not match also, I guess it was applied-filed but not registered due to the economic crisis in late '30s in the United States.
- CH159200 from 1932, registering a fold lever crown. The fold lever is functioning as a crown and is also locking the 2 pieces case to each other once fold in. An example can be seen in my archive. I am fortunate to have one cased in 14K gold.
- CH323980, registering the 'sweeping seconds hack' by Georges Godat.This unique invention is used only by Glycine even though it's not patented on the company name.It has been applied in March 1955 and registered in Aug 1957. This patent also helps us to date the very first Glycine Airman. Any Airman casing Felsa 692 having no hack mechanism would have been manufactured before March 1955.
- CH148534 from 1931, registering dial window for jump hour, minute and seconds watches. Unfortunately I have neither seen nor I am owning yet one of these timepieces by Glycine. Several diagonal case jump hour watches from the '30s are available in the second hand market but they are not signed by Glycine.
If you own one by Glycine or Eugene Meylan,send me some images I would love to display it in my website.
