Hi Mel,
please give me some more info:
1) diameter of case without winding crown - either 33mm or 35,5mm
2) does the watch have a sub second dial (second above "6" position) or center sweep second hand?
Then I will be able to tell you the reference number.
The number you mentioned is the case serial# and not the ref. #
Best would be a picture!
You can post a picture here or send me a pic via private mail.
kind regards
Erich
