Vacheron Constantin Toledo & Curvex Brief
Jul 21, 2024
Vacheron Constantin is one of the three members of the Holy Trinity of Swiss watchmaking — alongside Patek Philippe and Audemars Piguet — and one of the oldest continuously operating watch manufacturers in the world. Founded in 1755, the brand has spent nearly three centuries defining what luxury horology looks like. This guide focuses on two of its most collectible vintage references: the Toledo Ref. 4963 and the Curvex Ref. 35204.

A Brief History of Vacheron Constantin
Jean-Marc Vacheron founded the company in Geneva in 1755. In 1819, François Constantin joined as a partner, giving the brand its current name. Key milestones include:
- 1839 — Georges-Auguste Leschot introduced the pantograph, enabling precision mass production of watch components.
- 1880 — The Maltese Cross became the official logo.
- 1906 — The first boutique opened in Geneva.
- 1970s — Despite the quartz crisis, Vacheron Constantin continued to innovate with mechanical watches.
- 1996 — The company joined the Richemont Group.
Throughout its history, Vacheron Constantin has been synonymous with complications — perpetual calendars, minute repeaters, tourbillons — and with the kind of finishing that separates a truly great watch from a merely expensive one.
Vacheron Constantin Toledo Ref. 4963 (1950s)
The 1950s and 1960s are widely regarded as a golden era for vintage watches — a period of exceptional classical watchmaking and the birth of the modern sports watch. Vacheron Constantin played a central role, producing timepieces that have since become icons of the era.
The Toledo reference 4963 is a square-shaped time-only dress watch produced in the 1950s, available in white gold, pink gold, and yellow gold. At 23mm, with soft rounded lugs that add subtle depth to the design, it epitomizes the formal dress watch — suited for black-tie or white-tie occasions. The reference is also known as the Cioccolatone (Italian for “little chocolate”) for its resemblance to a square of chocolate.


One particularly striking feature of some examples is the oxidation of the gold case, which produces a distinctive bluish-red hue on the hands, right side of the case, crown, and clasp. This oxidation is not for every collector — but for those who appreciate it, it makes each watch entirely unique, as no two pieces oxidize identically.

Toledo Ref. 4963 — Specifications
- Case: 23mm square with rounded edges, white gold, pink gold, or yellow gold
- Dial: Simple dress dial, applied indices, classic hands
- Movement: Calibre 1003 — high-precision manual-wind mechanical movement
Vacheron Constantin Curvex Ref. 35204 & 35207
The Curvex references are celebrated for their elegant curved case design — a hallmark of Art Deco watchmaking. The Ref. 35204 was made in the early 1980s in yellow gold: a very fine, thin, rounded rectangular curved case that sits beautifully on the wrist.

The closely related Ref. 35207 was produced in the 1970s alongside the Prestige de la France Asymmetric range. Its faceted rectangular case, dial, and crystal are all curved, resulting in an impressive and bold design. It houses the Calibre 1052 ultra-slim manual-wind movement.


Curvex Ref. 35204 / 35207 — Specifications
- Case: Two-body solid, polished, snap-on case back, hooded lugs, sapphire crystal
- Design: Curved rectangular — case, dial, and crystal all follow the curve
- Dial: Clean and elegant; also available in satiné champagne with yellow gold Dauphiné hands
- Movement (Ref. 35204): Calibre 1015 — fausses côtes decoration, 20 jewels, straight-line lever escapement, monometallic balance, adjusted to heat, cold, isochronism and 5 positions, flat balance spring
- Movement (Ref. 35207): Calibre 1052 — ultra-slim manual-wind
Why These Watches Matter
The Toledo and Curvex represent Vacheron Constantin at its most refined — dress watches built without compromise, in precious metals, with movements finished to the highest standard. For collectors who appreciate the golden era of Swiss watchmaking, these references offer a direct connection to that tradition. They are also genuinely wearable: slim, elegant, and suited to any formal occasion.
