Hello,
AFAIK Breguet uses Pt cases only for its grand complications as repeaters and tourbillons.
3330 in YG and WG is one of the most beautiful pieces they made and make,but only triple-calendar,no perpetual.
Production numbers of non-limited editions are not disclosed by companies.
Would not make any difference anyway,as Breguet is no brand for speculations and watches generally are bad investments in a monetary sens as we know.
regards,
Lutz
