4400 SQ description
While the openworked architecture of Calibre 4400SQ reveals a wealth of fascinating hand-engraved work, it should in no way eclipse the technical performances of this splendid mechanism. Beating at a frequency of 28,800 vibrations per hour, the movement displays remarkable precision and offers an impressive 65-hour power reserve that is extremely user-friendly for a hand-wound calibre. Nonetheless, the mechanical aspects alone are not the only features to meet the highest standards of Fine Watchmaking, since the entire model is certified by the Hallmark of Geneva – a guarantee of quality, provenance, craftsmanship and durability appplying to the watch as a whole and providing the firm assurance of owning a timepiece that is exceptional in every way.
