..........You wait for the one you want to turn up and Three come along at once.
I have been on the look out for a nice 1930's piece for a while now and the Eberhard and Vertex turned up at the watch fair, I dropped the Ingersoll rex off today and this was my watch maker said I have something that may be right up your street, anyway the price was more than reasonable so it came home with me.
Nice dial with Copper chapter ring
Nice case back
Only 28mm, small but perfectly formed
Rose gold bezel, solid or capped I don't know but nice touch all the same
I've done a quick search on Mikrolisk and Driva were either a brand of Hirsch (the strap people?) or the Kelton watch Co New York, now no where does this watch say Swiss or Swiss made so does that help track down it's origins?
Oops just noticed the Large SWISS MADE on the case back
