Antique GP watch

Nov 19, 2017,23:46 PM
 

Greetings, my wife bought me this antique watch around 20 years ago from a fine jeweler in Chicago and it has been safely stored since then.  I haven't even polished it up yet but it is in perfect condition and keeps precise time. I have searched and cannot find a similar watch online. I was hoping a GP expert here could help me.  It is manual wind and I doubt the band is original as it says deDeer Paris. 

Inside I found the following identifying marks:  17 jewels, Swiss, 14k (0,585), numbers 914135, numbers 115 in a shape, the complete GP logo seal, another seal that looks like an animal standing, several signatures etched into the gold and, what I imagine was a later addition by a jeweler in green ink is the mark 999K.

Does anyone know anything about this watch or have advice on how I can learn more. Thank you!

....I am no GP expert but l'd say this was a GP Vintage 1945 XXL small seconds. Best, John. ...  

Welcome here, Barry!

Your watch is a 1940's GP with the Calibre GP91 inside. The etched signatures are watchmakers markings while servicing the watch. Best Blomman ...  

Beautiful.

It makes me think to my old Hamilton Otis “Reverso”. Best wishes Alkiro ...
