I don't know of any 16 jewel 16s Gruens. Could you post a picture?
Lemme get back to ya, in a couple years...nah, just yankin your chain.  Yeah I had worked out calibre 21 wasn't 16 jewel a while back but appreciate the confirmation Snark.
No, I can't post a pic of the movement unfortunately but the existence of a 16s/16 jewel Gruen is certain as it is documented in literature from 1904.
