See all of my no reserve auctions
for more vintage watches and watch parts including a solid gold Vacheron & Constantin Dress watch 
and watches by Longines, Wakmann and Movado.
Plus a Rattrapante chronograph by Lowenthal and some triple date moonphase watches.

This auction is for a Minerva stainless steel mechanical wind watch in running strong, maybe even a little fast.  I do not know the service history and I would recommend any vintage watch receive a cleaning service in order to achieve reliable timekeeping.  The case is all stainless steel (Edelstahl in German) and has a bayonet mount style back instead of the more common screwback or snapback. The lug pins are fixed.  There is also a dust cover to protect the movement.  The number on the case back is 1170.  Measures 32mm diameter.
