The new-foThe new watch, however, has a very different movement from the flyback Valjoux caliber 222 in the vintage model. It uses the Blancpain caliber F388B – this is a column-wheel controlled, flyback automatic chronograph with vertical clutch, and which runs at 5 hertz, or 36,000 vph, giving the chronograph a 1/10 of a second resolution.
r-2019 model is very slightly larger than the original (42mm, vs. 42.50 for the new model)
