From what I could gather the serial number puts it between 1929 - '35. Quite heavy for its size, 18k gold. The face is very small (2cm x 2.8cm) the watch is in excellent condition.
This watch is certainly not from 1929-35. I would guess it dates from 1960-70. The watch can be accurately dated from the serial number on the movement.
The value of this watch is dependent on the amount of gold in the case/bracelet.
