The perpetual calendar complication requires miniaturisation
prowess in that the movement must be mechanically adjusted
to deal with calendar irregularities. This miniaturisation
has been pushed to the limit in order to create an ultra-thin
perpetual calendar, with Vacheron Constantin’s Calibre 1120
QP measuring a mere 4.05 mm thick. This feat of engineering
with its openwork Maltese cross-shaped oscillating weight
comprises no less than 276 components, finished in accordance
with the highest standards of Haute Horlogerie. Performing a
magical and mesmerising ballet, the latter proudly display their
exceptional level of finishing through the transparent sapphire
crystal caseback of the watch. Finally, the steady beating of its
heart at a rate of 2.75 Hz (19,800 vibrations per hour) ensures
the precision of the movement as well as its 40-hour power
reserve.
Introduced with a pink gold case that makes a perfect match
with the sunburst satin-finished blue shade of the dial, and
equipped with a folding clasp, this watch naturally conveys
the personality of its owner: a timelessly elegant aesthete who
matches his appearance with the dark blue of the alligator
leather strap, of which the back is also lined with the same
leather in an ultimate touch of refinement.
