I was browsing some watch sites and came across a picture of this JeanRichard Bressel 1665 with power reserve. It seems to have its own in-house JR1000 movement by JeanRichard, case size of 42mm and a saphire display back.
Prices are just below 6000 Euro according to the Girard-Perregaux forum at The Purists.com (JeanRichard and GP are connected in some way…).
The Bressel handwound version (not displayed here) is probably around 2000 Euro, according to the same source. It lacks a power reserve feature ofcourse 🙂
