Here are a couple of scans from 1970.
I didn't notice a difference at first, but check out the Seamaster Chronometer in the bottom right corner. It's Stainless Steel in one advert & Solid Gold in the other.
Here's a scan from 1971.
This is very similar to the 1970's adverts above.
The watches are the same, only the picture sizes & text differ slightly.
These adverts are from 1972.
Notice the prices in the following advert. The PloProf is cheaper than the f300 ! & check out the sequence of the wording on the PloProf dial. Seamaster 600 Professional.... It is NOT the same sequence as the other adverts featured on this page.
A 1972 advert featuring a Seamaster f300.
Here are some great adverts from 1973.
What is really interesting ( from a Seamaster point of view) for this advert is that the PloProf has a RED crown lock. As far as I'm aware Omega never sold a model like this. This is a picture of the prototype.
This advert was also published in 1973 ( two months after the previous advert ) Although it looks similar to the 1972 advert (same pictures), the text is completely different.
Here are some f300 Seamasters available in 1973
Here's another drom 73 featuring a Chronostop an f300 Diver & a 1040 Seamaster.

I don't think Omega will have a problem with me reproducing these pages on the internet. They are good enough quality that they can be used, but not so good that people can copy, print & sell them as originals.
I have written this page to share the limited knowledge & information I have. Please don't abuse me, my work or other peoples pictures. It's not a nice thing to do !
Finally, It pisses me off that I have to write a disclaimer like this !
