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 ??
