Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin: Pink Gold & Burgundy at 8.1mm

Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin: Pink Gold & Burgundy Elegance

Vacheron Constantin has expanded its Overseas perpetual calendar lineup with two breathtaking new references, each featuring solid gold cases and striking dial combinations. Released in August 2025, these ultra-thin perpetual calendars prove that high complication and everyday wearability can coexist in a single timepiece.

Two References, Two Personalities

The new Overseas Perpetual Calendar Ultra-Thin collection comprises two distinct references, each offering a unique aesthetic interpretation of Vacheron Constantin's perpetual calendar complication:

Reference 4300V/220R-H144 — Pink Gold

This model pairs an 18k pink gold case and bracelet with a 5N pink gold dial accented by blue details. The moonphase disc is crafted from matching rose gold, creating a warm, monochromatic presentation that radiates luxury.

Reference 4300V/220G-H151 — White Gold & Burgundy

A more contemporary interpretation, this reference features an 18k white gold case and bracelet with a stunning burgundy sunburst lacquer dial. Blue accents provide contrast, while a matching burgundy moonphase disc completes the cohesive design.

Ultra-Thin Perpetual Calendar Engineering

What makes these references truly remarkable is their slim profile. At just 8.1mm thick with a 41.5mm diameter, the Overseas Perpetual Calendar Ultra-Thin is one of the thinnest perpetual calendar sports watches on the market. This is achieved through Vacheron Constantin's legendary caliber 1120 QP/1, a movement with deep historical roots.

The Caliber 1120 QP/1 Legacy

The caliber 1120 QP/1 is one of the most celebrated perpetual calendar movements in watchmaking history. Originally derived from the legendary Jaeger-LeCoultre caliber 920 — the same movement used in the Audemars Piguet Royal Oak and Patek Philippe Nautilus — Vacheron Constantin has refined and modernized this base over decades.

Operating at a leisurely 19,800 vibrations per hour (2.75 Hz), the movement prioritizes longevity and accuracy over high frequency. The 40-hour power reserve is adequate for daily wear, though the watch should be wound or worn regularly to maintain perpetual calendar accuracy.

Three-Strap Versatility

True to the Overseas collection's DNA, both references ship with three interchangeable strap options: the matching precious metal bracelet, a rubber strap, and a second rubber strap in a complementary color. This triple-strap system — requiring no tools for swapping — transforms the watch from boardroom formal to weekend casual in seconds.

Pricing and Positioning

Both references are priced at $120,000 USD, positioning them firmly in haute horlogerie territory while remaining competitive against comparable perpetual calendar sports watches from Audemars Piguet and Patek Philippe. The burgundy-dialed white gold reference has generated particular collector interest for its bold, unconventional color choice.

Frequently Asked Questions

How thin is the Overseas Perpetual Calendar Ultra-Thin?

At just 8.1mm thick, it is one of the thinnest perpetual calendar sports watches available. For comparison, many standard three-hand sports watches are 10-12mm thick.

Does the perpetual calendar need adjustment?

The perpetual calendar automatically accounts for months of different lengths and leap years. It requires no manual correction until the year 2100, when the Gregorian calendar skips a leap year. If the watch stops running, a watchmaker can reset it to the correct date.

Is the burgundy dial limited edition?

No, both the pink gold and burgundy dial references are part of Vacheron Constantin's regular Overseas collection, though availability may vary by boutique.
