Swiss watchmaker Vacheron Constantin has introduced two new interpretations of the Overseas Perpetual Calendar Ultra-Thin
The new timepieces, part of the Overseas collection, which is inspired by the spirit of exploration and openness to the world, come in pink gold with a matching pink gold dial and white gold with a burgundy lacquer dial. Each comes with a 41.5mm case and 18-carat gold bracelet as well as two additional rubber straps in different colours.
Encircling the dial of the pink gold model, a minutes track is marked in blue. The bracelet and sunburst satin-finished dial boast a chic tone-on-tone aesthetic alongside the matching pink gold moon-phase display. A textured rubber strap in blue or white can be interchanged with the gold bracelet.
The cool tone of the white gold case creates a rich contrast with the burgundy lacquer dial, which is matched by a burgundy moon-phase disc; further contrast is provided by white numerals and indexes. The two rubber straps come in a choice of burgundy or white.
The ultra-thin self-winding movement, Manufacture Calibre 1120 QP/1, incorporates a perpetual calendar and moon-phase display. A perpetual calendar is among the most challenging complications due to the complex arrangement of months of different lengths and an additional day in February every fourth year. Like a miniature mechanical computer, a perpetual calendar must automatically adjust to take these anomalies into account; it needs no manual correction until 2100 and, after that, only for the centenary years that are not leap years.
Calibre 1120 QP/1 drives the perpetual calendar functions – with the day of the week, date, month and leap year on a 48-month counter – as well as the hours, minutes and moon phase display. The movement beats at a frequency of 19,800 vibrations per hour and offers a 40-hour power reserve. Comprising 276 components, including 36 jewels, it is just 4.05 mm thick – a feat of miniaturisation that epitomises Vacheron Constantin’s approach to watchmaking.
The transparent sapphire caseback reveals a 22-carat gold oscillating weight adorned with a compass rose that symbolises the Overseas spirit of travel and exploration. The meticulous Haute Horlogerie hand-finishing work is also revealed, including Côtes de Genève, straight-graining, chamfering and circular-graining, enhancing the play of light across the movement.
