Any information on this UG Compax Chronograph would be appreciated

This came up as one of those "suggestions for you" while I was killing some time on the chrono24 website
I don't own any Universal Genève watches and sadly, don't know as much as I would like about the brand, beyond being aware of a rich history.
This one caught my eye purely for it's uniqueness and attractive dial, and what seems to be a reasonable price
Here is some info from the ad....
Reference: 698.400
Dimensions: 39.5 mm excluding original crown
Movement Type: very fine self winding caliber UG 98 in very good working condition
Case: stainless steel and solid yellow gold (BEZEL)
Crystal: Sapphire
Seller does not indicate date of manufacture, looks more modern than vintage to me?
Thanks

Definitely modern. If that is a real UG, the brand has definitely fallen on hard times. That bezel is hideous IMO. Looks like a Valjoux 7750 layout.

Edit: Did a quick search and it looks legit. Although most photos show a tachy bezel. I suspect that the UG 98 is a lightly modified 7750. Not from UG's golden years.
