So here we go, I've received this unique timepiece back from service and am ready to present it.
It's believed to be the prototype of what Eugene Meylan invented back in 1930. The movement, case and see through case back was examined and parts were confirmed to be coherent with its era from early 1930's. Detailed investigation and technical data can be seen in Dr. Ranfft's site where it has been re-surrected: bidfun-db Archive: Watch Movements: Glycine Eugene Meylan
I've also realized that some other forums in different languages are referring to WUS for information, I am happy that for. If our Spanish friends post that beautiful Pretto here in WUS ( Vintage, Amigos & Cia. al 19/07/2013 - Automáticos Primitivos - Vintages ), I will be happy to explain and clear the relation between Pretto and Glycine,that sounds more convenient since I don't speak Spanish.
Back to the Eugene Meylan Automatic aka E.M.S.A ( Eugene Meylan Société Anonyme )
Eugene Meylan invented the module, which could turn most of the 8.75''' lignes movements to automatic mechanisms :
For some reason there is confusion in his attempts to register this invention. First he secures his invention by applying for a patent on his own name ' Eugene Meylan, La Chaux de Fonds '. The invention is registered by two files: CH 149137 and CH 148138 in 15 Oct 1930
Then he decides to buy a company with the name ' Chronomuri SA ' and registers it as ' Automatic EMSA ' in the trade office.
He attempts to change or make addition on 9 June 1931 to his already existing patent with his new company which is announced in La Chaux de Fonds Chronicles:
The patents announced above, CH 77878 and CH 77588 are marked on early Automatic Modules. For some reasons they are not registered and they refer now to unrelated patents so as:
jigsaw (CH81653),
a drive-belt protector (CH77588),
two chemical processes for colors (CH77878, CH81251),
a twine machine (DE114688),
and an oil can (DE114720).
Carrying the patent through 2 companies he owned, Eugene Meylan makes one more attempt and transfers the patents to Automatic EMSA and registers them with different pat numbers in 5 March 1931:
He struggles with financial challenges add tries to protect his patent. Meanwhile looking for distributors in all countries to internationally spread his invention:
He tries hard for marketing. Creates together with Doxa SA, Meyer & Stuedeli ( Roamer ) and Glycine a marketing network in Germany to boost sales in the Reich-in those times. The office was in Berlin and the company was called ' Medex '.
The automatic module containing watches were also cased by different brands. I saw so far Helbros and Pretto watches with these modules, who knows we might see more surfacing while more information is revealed.
The watches from 1930 to 1935 carry the mark EMSA on the module, in 1935, Eugene Meylan transfers the patents to Fabrique d'Horlogerie La Glycine ( La Glycine Watch Factory, Uhrenfabrik La Glycine ) in 27 Aug 1935 and the EMSA mark disappears from the module and carry relevant Swiss patent numbers:
But again the US patents don't match
Tough time those 1935 to 1942 era, big recession pre and during WW II, I am not blaming anybody. Another applied for but not registered patents.
And this is now how Glycine Eugene Meylan Automatic looks:
No hassle to protect patents, beautifully paying tribute to its ancestors while they still tick around.
Glycine is an interesting company
The biggest mystery is still there though and I am still searching. Not sure why it wasn't credited enough even for barely modern patents in 1953 for the 24 hour bezel GMT function which is now widely used by most of the watch manufacturers.
Pritchard's Swiss Timepiece Makers - the bible for watch collectors says that Glycine manufactured self winding watches in 1910 !!!
Whether it was a pocket watch or wrist watch is not stated. The perpetuale (self winding ) by Perrelet was invented back in 18th Century. The known self winding wristwatches were first LeRoy in 1918 only 6 pieces and Harwood in 1923 for mass produced self winding wristwatches. If the information in Pritchard's book is correct, there is still more to discover.
Hope it wasn't a boring topic, thank you for reading,more information can be seen in my site: www.glycintennial.com
