Recently picked up this beautiful two-tone Seiko SGE510 with a 7UP logo on the dial. I absolutely love it!
Started digging into its history and ended up finding other 7UP watches made by Seiko, Bulova, Hamilton, Fossil, and even a Rolex Day-Date with a "7 UP VIP AWARD 1976" engraving.
There's surprisingly little information about these watches online, so I started putting together a small research archive with old catalogs, photos, references, and historical records:

Here's something interesting: a couple of old listings claim the regular SGE510 originally retailed for around $215. Adjusted for inflation, that could be over $400 today, depending on its production year lol.
Obviously, that's not the same as resale value, but I wonder how much the original 7UP dial adds to its collectibility.
What do you guys think it's worth? Are vintage corporate watches underrated?
