Fantastic topic. Speaking about pre war Polish Air Force watches there was one not long time ago on one of the listings. Acording to the description it seems to be from PZL P-37 bomber. Really nice piece although poor photos.
I own German 1947 Urofa/Ufag caliber 61 by Glasshutte. It is a small reminder of my Grandfather's service in Polish Army. I recently renovated it a bit and i am using it everyday.
