Here are two watches that I have never heard of until now. They are 15 jewel Prim and a 16 jewel Orator.
The Prim was made in Czechoslovakia, it has a date window and appears to be an automatic although it does not mention it anywhere. The case back is domed and the watch runs after been given a shake. The case measures 34mm across including the crown.
The Orator was made in Switzerland, it has a stainless steel screw back and is waterproof and antimagnetic. Although the case is badly worn I believe that it was originally gold plated. There is a number 1542
stamped into the case between the lugs which also appears on the movement.
