help me identify the age of my zodiac

[thstamatellos]

Hello and happy 2011

I have my grandfathers watch which is the zodiac shown in the photo.  It has 16 jewels and the number inside is 3AOJ with the indication Locle Geneve.

Any idea what the manufacturing date might be ?

Sorry, I don't do pocket watches. Anyone else?

Should be early 1900's - 1920's.  Not familiar with the caliber number though.  Honestly, I have never come across a Zodiac pocketwatch here, mostly American railroad stuff.  That is all anyone wants here, unless it is a European repeater or automaton.

Thanks for the replies so far.  around 1920, maybe a little before would be a reasonable date ...
