Hi, I would be VERY careful to buy anything from Ukraine. I you look at the other watches this seller offer they all are fake or pocket watch conversions.

This Heuer might be genuine despite this sellers bad reputation. The early Heuer logo looks right. It's rare too see this type of logo faked. Unsigned movement is normal for this period. It was not untill 1945 that Heuer signed all movements.
The chronograph seconds hand is wrong and to short. And I am not shure about the minute and hour hand either. Maybe they should have been of the cathedral type?

I think there's some genuine Heuer DNA in this watch, but I would be very careful to buy anything fra these Ukraine Beay sellers. I did buy a Heuer from these guys some years ago, and the so called original Heuer dial was actually printed on paper and glued to the movement.......

Best regards
