My pleasure. There also may be different rules that apply to the 3940 reference. A bit more research and possibly emailing him for an opinion might be helpful. [nt]

3940 Question/Concern
Hey all! I recently read a great article on Watch Brothers London about the differences between the series of 3940. This got me looking at my own 3940G which I've had a few years. According to the article all 3rd series watches have the sigma markers in l...
Did you check your serial number?
Your Sigma belongs to first series and second series. Does the '9' in your watch connect? If it does, it belongs to series 1. Are you the first owner?

J without the top lid is indeed an indication of later examples. Like how you will see on the 5140 and thereafter
Thank you for these articles!
The ACM and Watch Brothers London articles have been a great help as I begin my search for a 3940. I'll pose questions and thoughts in a separate post.
