Have used this forum many times to identify watch movements - thank you for the excellent pages and details you provide!
Have the following watch and am not sure what the movement is. It states 15 jewels Swiss made and on the back D33 (the 33 is written underneath the D). Is this a DuRoWe? If so why would it say Swiss made?
I am also interested what year roughly the watch was made.
Unfortunately the watch gained 15+ minutes an hour. Have cleaned the hairspring which was terribly sticky and now gains 2 - 3 minutes an hour. Will have to spend some more time to get adequate accuracy.
Thank you in advance for any help.
