I had the good fortune to be a guest of JLC at Palexpo and tried all three models. I own the previous model Chronographe.
The new models - shown below - were all nice in their own way, but not a giant leap forward. The blue dial was not to my personal taste - nor strangely was the salmon dial. Not sure the price increase makes them as good value as the prior models - but I did like the Moonphase in the Chronographe - nice touch.
I think if someone was looking to add a Duometre to their collection for the first time they would do well to look in the previously owned market given the price increases.
