It makes it much easier for us if the pics are hosted here.
First: they don't die when the other hosting site dies or starts charging unreasonable fees and blocking unsubscribed people.
Second: If they are on here we can download the image and enhance clarity, colour and balance to identify things not visible in the posted image.
I鈥檓 inclined to suggest that the dial is a later one.
I鈥檝e five Geneves, all 1968-1970, and all have the single bar 12 marker, not the double as in @duubuu's post.
I googled 10** and 1481 movements and there were examples of the 'double top' shown. Ranfft says all made 1972-1980/1984. I鈥檇 go for one of these.
The final piece of the puzzle is the caseback shown in the watch in the DavidT sales post you link to above. I think I have found your mystery Geneve, or at least something very similar. As you suggest this used the short lived collaboration movement, the 1481 which is part Tissot, part Omega. I think what you have is an early 1970s 166.098. There are subtle differences in the pics that google throws up for this reference, I think it straddled the era when they changed the logo and went from applied to painted but I do think this ticks most of the boxes.
Here is one that was sold with more pics, looks a lot like your dial and caseback

A couple of hours? Sometimes I've spent a couple of days (or more) checking out a watch before buying.
I think we can call it "BINGO" until the OP has provided inside pics of caseback and movement.
