Vacheron Constantin is a watch brand with a very long history. Its founder, Jean-Marc Vacheron, hired his first craftsmen for his workshop in 1755, marking the founding of the brand.
From its founding to the present day, the transmission and respect of watchmaking knowledge and precious craftsmanship have played an important role in the brand. Vacheron Constantin is based in Geneva, Switzerland, and for nearly 100 years, the Quai de l'Ile, located on an island in the Rhône River, was the headquarters of Vacheron Constantin. Since 2004, the Geneva suburb of Plan-les-Ouates has been the base of production and international headquarters.
This time, we will introduce five key points about Vacheron Constantin.
1. Reference 57260: One of the most complicated watches ever made

The reference 57260 features 57 complications. The Caliber 3750 movement contains over 2800 components and fits into a 72mm diameter, 36mm thick movement. It is hand-wound (Caliber 3750). 242 jewels. 18,000 vph. Approximately 60-hour power reserve. 18K white gold case (98mm diameter, 50.55mm thick).
In 2015, Vacheron Constantin celebrated its 260th anniversary with the introduction of the reference 57260, a pocket watch featuring a total of 57 complications, including a Hebrew perpetual calendar, an astronomical display, a world time display for 24 cities, and a double retrograde split-seconds chronograph.

2. Different blue dials for each collection

Automatic movement (Cal. 2460 R31R7/3). 27 jewels. 28,800 vph. Power reserve approximately 40 hours. 18KPG case (diameter 42.5mm). Price: 638 million yen (tax included).
Luxury brands like Vacheron Constantin are known for their attention to detail, setting them apart from other watchmakers. For many years, Vacheron Constantin has produced watches with beautiful dials, with different shades of blue dials for each collection.
The blue of the Overseas collection is achieved by combining a galvanic blue with lacquer. The blue dial of the Patrimony collection, which Vacheron Constantin calls "Majestic Blue," is also galvanic. And the petrol blue of the Fiftysix is a PVD treatment.

Automatic movement (Cal. 2160). 30 jewels. 18,000 vph. Power reserve approximately 80 hours. Stainless steel case (diameter 42.5 mm). Water resistant to 5 bar. Reference price: 1632 million yen (tax included).

Automatic movement (Cal. 2460 QCL/1). 27 jewels. 28,800 vph. Power reserve approximately 40 hours. Stainless steel case (diameter 40.0 mm, thickness 11.6 mm). Water resistant to 3 bar. Price: 3,762,000 yen (tax included).
3. The "American" with a tilted dial

In 1921, Vacheron Constantin created a special wristwatch called the "American 1921." The dial was tilted at a 45-degree angle, and the 12 o'clock hour marker was placed on the corner of the case where the crown was located. 24 models were produced in the United States, and there were two variations.
One has the crown and 12 o'clock index located in the upper left (between 10 and 11 o'clock on a regular watch), and the other has them located in the upper right (between 1 and 2 o'clock on a regular watch).
In 2008, Vacheron Constantin reissued this model, equipped with the in-house caliber 4400. In 21, to commemorate the 100th anniversary of the birth of the American 1921, a unique piece was produced that faithfully reproduced the original model.

Manual winding (Cal. 4400AS). 21 jewels. 28,800 vph. Power reserve approximately 65 hours. 18KPG case (diameter 36.50mm, thickness 7.25mm). Water resistant to 3 bar. Price: 5,236,000 yen (tax included).

4. Watches with Retrograde Displays

Vacheron Constantin is well versed in all complications, especially retrograde movements. Around 1930, the company, then called Vacheron & Constantin, produced a pocket watch called "bras-en-l'air" ("arms in the air"), with two hands displaying the hours and minutes retrogradely.
A distinctive feature of retrograde displays is that when the pointer reaches the end of the display, it returns to its starting point and resumes measuring from there. In the 1990s, Vacheron Constantin attracted attention with a watch that paid homage to the cartographer and geographer Gerardus Mercator (1512-1594). The dial features a map drawn using the Mercator projection system, and two long hands that indicate the hours and minutes.

5. Craftsmanship

Automatic movement (Cal. 2460 G4/2). 27 jewels. 28,800 vph. Power reserve approximately 40 hours. 18K White Gold case (42mm diameter). Water resistant to 3 bar. Estimated price: 22 million yen.
Craftsmanship, known in French as "métiers d'art," plays a major role at Vacheron Constantin. Engraving, guilloching, gem-setting, and enameling are key techniques for the brand. These techniques, which require a great deal of experience and skill, are all performed in the brand's Geneva workshops, where many employees have been with the brand for many years. Each year, Vacheron Constantin releases watches that combine multiple of these techniques.
A recent model is the "Métiers d'Art - Homage to Great Civilizations." Created as part of a partnership between Vacheron Constantin and the Louvre that began in 2019, it features four rare models, each limited to five pieces. The themes chosen are the Lion of Darius, the Winged Victory of Samothrace, the Bust of Augustus, and the Great Sphinx of Tanis. The center of the dial is adorned with intricate engravings characteristic of each period. The Lion of Darius features cuneiform inscriptions, the Winged Victory of Samothrace in Greek inscriptions, the Bust of Augustus in Latin inscriptions, and the Great Sphinx of Tanis in hieroglyphics.
The hour, minute, date, and day of the week displays are located at 2, 4, 8, and 10 o'clock on the dial, and are powered by the in-house caliber 2460 G4/2. These models are exclusive to Vacheron Constantin boutiques and have an estimated price of 2200 million yen.
