Very nice collectable 1940s Universal Geneve reference 20103 serial number 14xx,xxx center second manual wind watch in excellent condition. Watch is 32mm approx in size so suitable for man, woman or child. Could be a military watch (guessing). Watch works great keeping excellent time and running like a train. Movement is squeaky clean having just been serviced and has a dust cover. Dial and hands are clean and original with some patina. Watch and hands retain their original lume (radium) which only lights up for a few seconds when expose to UV. Nice original entry level collectable UG which is increasingly rare to find. Grab it while you can at £210.00 delivered.
Very nice watch for anyone open to smaller sized cases, and fairly priced. Not military, though. GLWTS.
I do not know, but, while I am no expert in military watches, they were typically marked as such on either in inside or outside of the case back, or both.
Most stainless steel Taubert (FB) cases of this era had a 4(?) digit number between the lugs. It should match with the last four digits of the case (serial) number that appears on the caseback. It ensures that the parts belong together.
