This wristwatch was made by a Swiss company, Butex, in the early 50s. I think this company no longer exist. The watch is powered by a manual winding, 17 jewels and anti-magnetic movement which has the following functions:- hour, minutes, seconds, day, date, month, moon phase and a 30 minutes chronograph timer. You can see the 1950s sales ad for this watch in picture 3.
