the smallest teeniest tiniest automatic watch movement ever... Cal 661 in the Omega Ladymatic Sapphette / Saphette
smaller than a 10 cents coin...
gracing folk's wrists then...
As fate would have it, a colleague of mine happens to be into vintage items and she picked this up some time ago in a mystical vintage watch shop that disappeared in a fog minutes after her purchase ;) [Thanks Elissa!] (fyi some price references but highly dependent on condition LINK3 LINK2 LINK1 )
One thing though is with me getting my paws on it and handling it, I can open the back and have a look at the movement... and that's when it hits home how tiny this auto movement is and how small they can make 'em if they wanted to. of course they don't coz BIGGER is better these days but holding this watch, you almost don't believe there could be a mechanical movement inside let alone an automatic one.
Movement: Diameter of 15mm, Height of 4.25mm. 24 jewels, 19800bph, fixed stud carrier with
beryllium bronze ratchet wheel, self winding
this version with gold plating of 20 microns per the caseback
hope you enjoyed the short post as i had enjoyed doing it up... a nice break from the usual mumbo jumbo :) cheers, raph
