I have never really embarked on the JLC Chronographs series as a collecting thema. I don't really know why. Maybe it has to do with the fact that they were non in-house, or maybe because I never really crossed a good one in my early days of collecting that could have sparked the fire for the next ones (I only have one UG-powered one).
But I reckon that these R72-powered have a huge personality, and the case and bezels of both the Shark and the 4 ATM are particularly well constructed and attractive, and no doubts if one of these was crossing my path today it would be a totally different story.
Thank you for the detailed and comprehensive review as usual !
(and yes, this GMT chrono... definitively one to forget for ever....)
