SETTING THE TIME
The Duomètre Quantième Lunaire watch fea-

the “jumping stop-seconds”. This enables the
two hands to be reset by the crown and for the
time to be set on the watch once an hour signal
sounds to a precision of 1/6th of a second.
Pull Crown A out to position 2. The jumping
seconds hand returns to zero and stops in

Note that the escapement continues to
function, thanks to its dedicated power reserve.
Its isochronism is undisturbed.
