hello and Merry Christmas to everyone
I bought this Zenith pocketwatch at Christmas Eve for 80 euros
On the back writes : Metal Blanc Garanti 5087478 3914. Also in the upper part as you can see it has the letter "E" written.
As you can see the dust cover has the words "GRAND PRIX PARIS 1900" and the same numbers "5087478 3914"
the diameter of the movement is about 38mm. The serial number is 1964131. Also it has the number 3914 just above the serial number.
so can you give me more info about the movement, the case, when it was made , etc ;
