Vacheron Constantin have created two new versions of the Overseas Perpetual Calendar Ultra-Thin in pink gold with a matching pink gold dial and in white gold with a burgundy lacquer dial.
Both models are presented in 41.5 mm cases with 18K gold bracelets and two additional rubber straps in different colours. With its distinctive design inspired by the Maltese cross, the emblem of the Maison, the Overseas collection deftly balances sporty attributes and casual elegance while the Overseas Perpetual Calendar Ultra-Thin model perpetuates the legacy of ultra-thin watchmaking that has long distinguished Vacheron Constantin.
Encircling the dial of the pink gold model, a minutes track is marked in blue – a subtle punctuation in the chic tone-on-tone aesthetic of the case, bracelet, sunburst satin-finished dial and matching pink gold moon-phase display. For a more casual and sporty allure, 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 provided by white numerals and indexes. In a choice of burgundy and white, the two rubber straps that can be interchanged with the 18K white gold bracelet give the option of a richer palette matching the dial or a cooler palette harmonising with the case and numerals.
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 for watchmakers to master because the calendar that governs our lives is a complex arrangement of months of different lengths and an additional day in February every fourth year. This is due to the difference between the measurement of civil time and the astronomical phenomena on which those measurements are based. 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 22K 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. Every component of a Vacheron Constantin watch benefits from this scrupulous attention, including those that remain invisible once the movement has been assembled.
As a travelling companion, the versatility of the Overseas Perpetual Calendar Ultra-Thin watch is underlined by the practicality of easily interchangeable straps that can be quickly changed without requiring any tool. From the refinement of 18K gold bracelets to the sporty-chic allure of rubber straps, the watch quickly adapts itself to multiple styles and situations. Pink gold is complemented by a choice of white or blue rubber, while the white gold is accompanied by straps in white and burgundy.
