G'day,
some answers!
The JR1000 caliber is "in-house"; technically GP and JeanRichard do share some ressources, but the movement is designed, developped and manufactured in-house and for use by JeanRichard exclusively.
So i think it´s as much JR as it gets!
The chronograph module, to my best knowledge, is a Dubois-Depraz module especially fitted for the JR1000.
It´s a cam/lever chronograph and in general, comparable to those modules in use by GP for three-register chronographs (where experience with these modules is promising to be a very reliable, trouble-free and accurate timepiece).
If you compare it to Patek´s new 5960/5860, you will probably notice quite a gap in terms of the price. This goes back to the R&D work behind the integral chronograph, but the finishing too (and certainly the name).
Both Rolex and Zenith are integral chronographs (as is the JLC) and i´d guess all are made in fairly higher production totals than the JeanRichard.
In this, it´s certainly different and not intended to rival the Patek or Rolex chronographs; much more to be an interesting addition in a somewhat more affordable price range. I´d guess it will do very well as a daily wearer, for those who appreciate the design, the wearing comfort (it´s really a very comfortable watch) and the fact it´s coming from a very small brand that is not part of the large conglomerates.
It´s probably not as beautifully finished as some 5070´s around, but then you don´t have to pay the same price too
And it´s much more targeting those enthusiasts who do have the self-confidence to wear a nicely made watch without an instantly recognizable brand name on the dial, but a rather classic and modern look and feel!
If you like the pictures, i´d recommend to see and try it.
I´m sure the Bressel Chronograph will speak for itself quite a bit more than you may expect!
Cheers,
Peter
