I'm not sure, except that I know it's in the 80's. I did a search using Larry's fabulous search engine and found the production dates of the cal. 4205 here:

/scwf/msg/1006825313

It's 1982-1987.

I would assume the diver's production dates coincide with the movement dates, but then I'm just guessing.

If someone else know more, please correct me!
