He wouldn’t need to be a specialist in vintage UG, Breitling didn’t buy the company to express their deep appreciation for the vintage models. They bought it to put UG back to work producing new watches to sell to the public, and Eric definitely knows the market well and has a big Rolodex of vintage watch customers.
The only reason the Breitling purchase makes sense to me at least is that Breitling also owns Kelek, the manufacturer of piggyback perpetual calendar modules as well. These are what they use in the Breitling Montbrilliant among others.
Kelek branded modern watches are cool but not worth much and there’s no cult following. But if you take Kelek’s piggyback modules, put them on a modified Breitling chronograph, and remake some of the greatest UG hits of their golden era in a larger size, similar to Zenith’s recent vintage revivals, you’ve got a winning combination.
Given that Breitling is still owned by CVC Capital Partners, the former F1 owners from the Bernie era, I’d imagine they want to make a small investment here, turn it into something that’s an overnight hit and dump either it, or the whole package including Breitling on LVMH or Richemont once the market cap hits their targets.
That’s just my perspective, not based on any special information but it’s the most sensible approach to the new UG and explains the fit with Breitling.
