Let's see your early automatic watches

[Еmre]

Let's see what you have there in your collections.I have only 2 of the first 3 mass productions,maybe later some time will complete the herd with all the known early automatic mechanisms:

Harwood,the first mass produced self-winding wrist watch,from 1926 -31. Mine is hallmarked 1928 London in 9kt rose-gold case:







And the Glycine self-winding. Eugene Meylan's ingenious find - Oct 1930 ,the module which can be (un)mounted on most 8.75 lignes hand-winding movement and turn them into automatics:





The 'Rolls' is missing in-between though.Wig-wag and Pierce linear automatic is also in my radar,just waiting for the right time

Let's see those early inventions
