I got this watch recently and I have fall in love with it immediately, I
put one picture of it in to wrist shot part and since it got very warm
welcome I posting it where I think it belongs
Since I am not to good in dating vintage GP - I hope you will correct
me if I am wrong but this chrono looks like early fifties maybe but that
lower probability and in this case I would expect UG movement late 40's
Since pictures are more informative then words
as a comment
ihmo dial and hands are all original - with hands I had to restore a bit
of tritium fillings (swiss T) but I did it with original tritium paste
from 50's so I think all is ok here
also I have to say that those blue hands are amazingly beautiful



Now
case - screw back ,stainless steel "military type" with kind of bezel
chimney - I was lucky - got it in good I am pretty sure unpolished shape
with original finish - small cleaning and correction and it looks great
crown looks right but since they were not sign hard to have 100%, antimagnetic dust cover is still there





Now to the soul - inside beautiful and in great shape valjoux 72 signed both by valjoux and gp ,
Movement is placed in additional holding ring 


Thank you for looking at this 
My best
Rafal
