Welcome to the Forum. If you will post some pix of your watch, this will help us to identify it for you.
Have you checked under the "6" marker for any numbers, such as: 10356 10979. The "6" marker would be between the two sets of numbers. The numbers to the left of the "6" marker would be the catalog/model number. The numbers to the right of the "6" marker would be the movement number and the last two digits of the year of production. In my example, the movement number would be "109" and the year of production would be "79" for 1979.
Otherwise, you might pop off the back of the watch and see if there are any numbers stamped in ink on the inside of the caseback.
