W&W 2020: Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton

Vacheron Constantin Overseas Ewiger Kalender extra-flach Skelett 4300V/120R-B547 Watches & Wonders soldier front

Vacheron Constantin has introduced the Overseas Perpetual Calendar Ultra-Thin Skeleton watch. The model manages to integrate a perpetual calendar into a slim case measuring 41.5 mm x 8.1 mm. The completely skeletonised dial reveals the movement. However, the watch is available in 18-carat 5N rose gold only.

The sapphire crystal protecting the Overseas perpetual calendar ultra-thin skeleton’s dial and caseback allows for a view of the watch’s entire movement. This includes the complex perpetual calendar plus moonphase display.

The dial itself uses three subdials to show the day, date, month and leap year. The moonphase display lies at 6 o’clock and features the brand’s name. Additionally, the hour markers plus hour and minute hands are 18-carat 5N rose gold and are legible 24/7 thanks to a covering of fluorescent material. However, the watch has no seconds hand.

The skeletonised in-house calibre 1120 QPSQ powers the Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton. Despite its delicate height of 4.05 mm, the movement consists of 276 components, plus 36 jewels. The automatic calibre has a skeletonised 22-carat gold rotor. Moreover, it has a power reserve of 40 hours. It has a frequency of 2.75 Hz.

Calibre 1120 QPSQ

The Overseas Perpetual Calendar Ultra-Thin Skeleton comes with an 18-carat 5N rose-gold bracelet. The satin-polished bracelet’s links are shaped like a half of the Maltese cross. Additionally, a blue leather and a blue rubber strap are included. Furthermore, thanks to a simple bracelet system, the straps and bracelet are easily interchangeable.

Finally, the Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton is water-resistant to 50 m. It is certified with the Hallmark of Geneva. Price: EUR 130,000.
