Authentication Notes

Dial

HighProbable

The numeral sequence itself is specific

The out-of-sequence arrangement is a fixed pattern, not a random scatter, and it has to be consistent with the mechanism's jump programme. A dial whose numerals are scrambled differently from documented examples is a copy made by someone who understood the appearance and not the mechanism.

Movement

CriticalProbable

Watch it change hours — this is the whole test

Set the watch a few minutes before the hour and wait. The hour hand should jump instantaneously across the dial to the next numeral in the true hour sequence, which is not the next numeral round the dial. A hand that creeps, or that advances to the physically adjacent numeral, is in a watch that does not have the mechanism. This is the most decisive and least technical check anywhere in the Franck Muller catalog, and it needs nothing but a few minutes.
