Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin 41.5mm 18K 5N Pink Gold Gold Dial (Ref# 4300V/220R-H144)

All-Gold Vacheron Overseas Perpetual Calendar 4300V/220R

The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin 4300V/220R is the Overseas in full 18 karat 5N pink gold: case, bracelet and a warm golden dial. Vacheron lists the case at 41.5 mm across and just 8.1 mm thick, and inside is caliber 1120 QP, an ultra-thin automatic perpetual calendar movement 4.05 mm tall.

The video opens on a simple idea. A full gold watch has always been a definitive statement: beautiful, timeless and unapologetically opulent. This one keeps all of that and adds freedom, versatility and a little room for fun, with a tool-free strap system and two rubber straps in the box.

1. Dimensions and the 5N Pink Gold

Vacheron's official figures for the 5N pink gold case are 41.5 mm across and 8.1 mm thick, with 50 meters of water resistance.

Measured at 49.1 mm lug to lug and 8.5 mm thick on the caliper

On a 7-inch wrist the watch has a broad, confident presence and still sits remarkably close to the skin. Those proportions give the warmth and substance of a full gold sports watch along with the elegance of something far more dress-oriented.

The pink gold has a particularly rich tone. In the video it reads slightly warmer and more saturated than Rolex Everose gold, a touch less rose and a touch more yellow. With a case this slim, all of that gold takes on a graceful silhouette.

2. The Overseas Case

The Overseas has one of the most recognizable case designs in modern watchmaking. Its six-sided bezel draws on the Maltese cross, with polished edges set against the brushed surfaces of the case. The architecture is distinctly sporty, and the thinness gives it an almost dress-watch elegance. A screw-down crown and a sapphire exhibition caseback complete the case.

3. A Golden Dial with Blue Accents

The dial continues the rich monochromatic look, with a few touches of fun set against the warm gold. Subtle blue accents on the leap-year and month indication and on the outer minute track add a small burst of color. At a distance they almost disappear, and up close they grow more charming.

Four displays organize the dial: the day at 9 o'clock, the date at 3, the month and leap year at 12, and the moon phase at 6. Even with that much information, the layout stays calm and composed.

The moon phase is the standout. Vacheron treats it as a miniature celestial landscape, with a gold-tone moon and stars set against a finely detailed sky. The hands and hour markers carry luminescent material for legibility after dark.

4. Caliber 1120 QP

Caliber 1120 QP stands barely 4 mm tall, and within that height it tracks the day, date, month, four-year leap cycle and moon phase. It runs at 19,800 vibrations per hour with a 40-hour power reserve. The calendar accounts for months of different lengths and for leap years on its own, so as long as the watch keeps running and stays set, the date will not need correcting until 2100.

The sapphire caseback shows the finishing, the 22 karat gold oscillating weight and the Hallmark of Geneva. At this thickness, ultra-thin is an engineering achievement as much as a design choice.

5. Bracelet, Clasp and Rubber Straps

The bracelet is a beautiful piece of architecture in its own right. Rounded link surfaces meet sharp angular edges inspired by the Maltese cross, creating a distinctive play of light and shadow. The folding clasp has a discreet comfort extension: pull the clasp and push it in to adjust. On the bracelet, the watch is a bold, full gold statement piece.

Vacheron's tool-free interchangeable system swaps the bracelet for the supplied blue or white rubber strap in seconds, and the personality of the watch changes with it. The rubber brings a more casual attitude, while the gold case and ultra-thin profile keep enough elegance to look at home beneath a sports coat. It turns the volume down and keeps the presence. The full process is covered in our guide to changing an Overseas bracelet or strap.

Under the golden exterior are little touches of blue, a beautiful moon phase and details that feel reserved for the person wearing it. The video sums it up as opulent, versatile and surprisingly playful: the same full gold luxury, with more ways to enjoy it. The white gold Overseas Perpetual Calendar 4300V/220G-H151 pairs this caliber with a burgundy dial.
