The best-known and earliest maker of resonance wristwatches was and link is F. P. Journe, whose Chronometre a Resonance link launched in 2000, originally as a subscription piece. I was very skeptical link of the watch at first but realized after reading The Art Of Breguet, which goes into quite a lot of granular technical detail about Breguet's resonance watches, that Journe had followed exactly the same principles.
