I'm trying to establish a period - correct list of parts

[Lo']

Hello!

I have been putting together my 1016 build without considering the correctness of the parts I shoved at it.

A bit of research has left me with more questions than answers since:

I was convinced that all watches manufactured before 1970 (circa) would sport a slim legged "R" like so:

Therefore all watches produced after 1970 should have borne an "R" with its characteristic "triangular - shaped" leg. This detail would compel me to stick to a GS flat crystal instead of the superdome I have been fitting it with.

Then what happens is that I find this 1016m on Stefano Mazzariol's blog and the piece also is equipped with a superdome.

Now I'm confused. ...
