The Breitling Watch Source Forums

Hi!

I would greatly appreciate if someone could tell me anything about Zais Chronographe and Breitling connection, I have one from dad's collection, trying to find some info.
I hope it won't be a problem I posted similar subject on another forum, but there I asked is the watch from WW1, and here I would like to find out about possible connection with Breitling.
I was searching and found that one guy sells similar watch, which he named as "20's Zais Watch by Leon Breitling One Button Chronograph". He also wrote this in description : "Zais Watch by Breitling Zais Watch chronograph manufactured by Breitling. ZAIS was one of the brands registered for G.Leon Breitling SA."
There are some differences between that watch and mine; that one has 'Zais Watch' written on movement, mine doesn't. Mine also has 'Precision' written on dial, under the 'Zais Watch'.
Can anyone tell me about this quite unusual Zais - Breitling connection?
These are my watch's pictures :
