Cool watch Denis, I love these giant 1970 watches, I have a dozen or so of them in my collection. We never really found anything to ID them. They WANT to be Jet Stars but there are no adverts showing them as such. Later in the decade they might have been Clippers but again, no ads.
Alas, Unknown.
PS - Set-O-Matic is a sweet feature. Snap the crown fully out to advance the date, spin the crown to advance the day. You know what SWISS MADE, means, the "T" designates Tritium which glows the dial. It replaced the deadly radium used earlier.
With several out there, we really need an ad for these unknowns. I'm with Geoff on Unknown.
This appears to be a 1975 President Set O Matic (Watch on Right)

Agree that this one appears to be a Set-o-Matic. Here is another ad with this model. Says stainless with champagne dial or yellow gold and blue dial.

1974 Set-O-Matic works for me.
I think it would also be safe to say it is a President?
Nice work Jim, looks like a match to me.

According to the ad it is a “President” Set-o-Matic. The ad doesn’t specifically mention a yellow gold case with the gold dial But everything else seems to line up
I'm also finding other ads in the mid-70s for 17 jewel President models, with the Set-O-Matic feature.
I'm in for a President id.
