And you are right about the logo. Breguet likewise likes to advertise the 10Hz frequency on the dial.
As for the high frequency, itβs a feature I much appreciate for the idea, even if in practice the improvement to the time keeping doesnβt really seem to be there. Mind you, the watch is chronometer certified and manages to keep time within the parameters but thatβs something my 2,5Hz Minervaβs manage, too (even without certification π).
