Vacheron Constantin Overseas 4500V/110A-B128

Getting to Know Vacheron Constantin

Vacheron Constantin sits in the top tier of Swiss watchmaking alongside Patek Philippe and Audemars Piguet, with a manufacturing footprint that produces roughly 30,000 watches a year and hand finishing that targets the Geneva Seal across most of the catalog. The current lineup is built around the Overseas sport line, the Patrimony and Traditionnelle dress collections, the Fiftysix integrated bracelet line, the Historiques heritage reissues, the Métiers d'Art artistic series, and the Égérie women's collection.

How a Vacheron Constantin Reference Number Works

A Vacheron Constantin reference is built in two parts separated by a slash, often followed by a hyphen and a dial code. The first 4 or 5 characters before the slash identify the base reference and complication. The characters after the slash encode the case material and bracelet configuration. The B-number after the hyphen keys the dial color and specific variant.

Reference 4500V/110A-B128 reads as the current Overseas Self-Winding (4500V) in steel (110A) with the blue sunburst dial (B128). 85180/000R-9248 is the Patrimony Self-Winding in 5N pink gold. 4200H/222A-B934 is the Historiques 222 in steel; 4200H/222J-B935 is the same watch in yellow gold. 5520V/210A-B686 is the 2026 Overseas Chronograph at 42.5 millimeters with the Panda dial. 6000V/210T is the Overseas Tourbillon in titanium with the burgundy dial.

The metal codes inside the case designation follow a rough convention: 000A or 110A signals steel, 000R rose gold, 000G white gold, 000J yellow gold, 000T titanium, and 000P platinum. The first digit of the base reference is the fastest tell on which collection you are looking at: 4 prefixes most Patrimony and Historiques references; 5, 6, and 7 prefix the Overseas family; 4600 the Fiftysix; and 85180 the Patrimony Self-Winding date.

What the Specifications Actually Tell You

Movement and Caliber

Every Vacheron Constantin in standard production runs an in house caliber, and most are certified to the Geneva Seal, which requires the movement to be finished by hand on every component and tests the cased watch for chronometric accuracy, power reserve, and water resistance.

The Overseas Self-Winding 4500V runs Caliber 5100, a 60 hour automatic with a 22 karat gold rotor shaped to evoke a wind rose, beating at 4 Hz and bearing the Geneva Seal. The Overseas Chronograph 5500V carries Caliber 5200, a column wheel chronograph with the same 60 hour reserve. The Overseas Dual Time 7900V series uses Caliber 5110 DT with a second time zone display. The Patrimony Self-Winding 85180 runs Caliber 2450 Q6 at just 3.6 millimeters thick, which is what keeps the entire 40 millimeter case under 9 millimeters total. The Fiftysix Self-Winding 4600E uses Caliber 1326 with a 22 karat gold rotor. The Traditionnelle Manual-Winding runs the slim Caliber 4400, and the line's high complications carry calibers from the 2755 family for tourbillon perpetuals and the 1731 for minute repeaters.

The Dial

Vacheron Constantin dial work runs across the full spectrum of haute horlogerie technique, from the restrained sunburst finishes of the Overseas to the guilloché patterns engraved by hand on Traditionnelle and Patrimony to the enamel, gem setting, marquetry, and engraving of the Métiers d'Art series. The Overseas runs a half Maltese cross motif worked into a textured ground on most current references, with the blue sunburst dial as the signature configuration on the 4500V. The Patrimony uses a minimalist layout with applied baton indices and a railway minute track around the perimeter, and almost nothing else on the dial face. The Traditionnelle adds a fluted bezel and Roman numerals for a more classical read. The Fiftysix sits between the two with a sector dial and tapered indices that tie back to the 1956 reference 6073 the line is named for. The Historiques 222 carries a matte dial with applied gilt indices and a stamped 222 signature at 12 o'clock.

Case Material and Size

Stainless steel is reserved for the Overseas, the Historiques 222 steel variant, and the steel Fiftysix. Everything else in the catalog is offered in 18 karat gold (rose, yellow, or white) or 950 platinum. Titanium appears on certain Overseas tourbillon and complication references where weight is part of the brief. The Maltese cross emblem stamped onto the rotor, the crown, and the bracelet clasp is the visible brand identification on most references.

Case sizes vary by line. The Overseas Self-Winding 4500V is 41 millimeters and 11 millimeters thick. The Overseas Chronograph 5500V is 42.5 millimeters. The new Overseas Self-Winding Ultra-Thin 4520V is 39.5 millimeters. The Patrimony Self-Winding is 40 millimeters and just over 8 millimeters thick. The Traditionnelle Manual-Winding is 38 millimeters. The Fiftysix is 40 millimeters in a cushion tonneau case. The Historiques 222 is 37 millimeters. The American 1921 is 36.5 millimeters in a cushion case rotated 45 degrees so the crown sits at 1 o'clock. The Cornes de Vache 1955 chronograph is 38.5 millimeters.

Water Resistance and Crystal

The Overseas is the brand's only collection actually rated for swimming. The 4500V, 5500V, 7900V, and 4520V all carry 150 meters of water resistance with a screw down crown, which sits well above most luxury sport watches in the same category. The Fiftysix, Patrimony, Traditionnelle, Historiques, American 1921, and Cornes de Vache 1955 are all rated to 30 meters, fitting their dress watch role rather than any pool depth use.

Crystals are sapphire across the catalog with antireflective treatment. Casebacks are sapphire on nearly every current reference, exposing the finished caliber for review, with the exception of certain Métiers d'Art references where the artistic dial work fills both sides of the case.

Telling the Collections Apart

Overseas

The sport luxury anchor of the catalog, and the Vacheron Constantin reference most directly compared with the Royal Oak and the Nautilus. The current Overseas Self-Winding 4500V is 41 millimeters in steel, with a 60 hour Caliber 5100 visible through a sapphire caseback, a half Maltese cross bezel motif, and 150 meters of water resistance. Every Overseas in the current generation ships with three quick release straps (steel bracelet, rubber, leather) that swap without tools. The Overseas Chronograph 5500V at 42.5 millimeters and the Overseas Dual Time 7900V at 41 millimeters sit alongside, with the new Self-Winding Ultra-Thin 4520V at 39.5 millimeters in platinum and gold introduced for the 270th anniversary in 2025. The line tops out with the Overseas Tourbillon 6000V and the Overseas Perpetual Calendar Skeleton 4300V.

Patrimony

The classical dress watch line, defined by the slim case profile (8.55 millimeters on the Self-Winding) and a dial pared back to baton indices and a railway minute track. The Patrimony Self-Winding 85180 is the entry reference in 40 millimeters of 5N pink gold or white gold, running Caliber 2450 Q6 with a date at 6 o'clock. The Patrimony Manual-Winding is the two hand version at 6.79 millimeters thick. The line also covers a perpetual calendar, a retrograde day and date, and a moon phase with retrograde date at the upper end.

Traditionnelle

The high horology dress line. The Traditionnelle Manual-Winding at 38 millimeters carries the slim Caliber 4400 with a small seconds at 6 and a fluted bezel that distinguishes it from the cleaner Patrimony case. The Self-Winding version adds an automatic date caliber, and the Complete Calendar at the mid tier reads the day, date, month, and moon phase. The Traditionnelle Perpetual Calendar Ultra-Thin, expanded with three new references for the 2025 anniversary, is the signature complication of the line, and the Traditionnelle Tourbillon Perpetual Calendar sits at the top in platinum.

Fiftysix

The most accessible current Vacheron Constantin, launched in 2018 and named for the 1956 reference 6073 that inspired the case design. All Fiftysix references share a 40 millimeter cushion tonneau case with a four lug Maltese cross silhouette and a sapphire caseback exposing an openworked oscillating weight. The Fiftysix Self-Winding 4600E is the three hand date entry in steel or rose gold. The Complete Calendar reads the day, date, month, and moon phase. The Day-Date sits between the two, and the Tourbillon caps the line in rose gold.

Historiques

The heritage reissue line, drawing on specific archival references rather than a general vintage vocabulary. The Historiques 222 is the modern reinterpretation of the 1977 Jörg Hysek integrated bracelet design, available in yellow gold (4200H/222J-B935) or steel (4200H/222A-B934, added at Watches and Wonders 2025) at 37 millimeters with a matte dial and Geneva Seal. The American 1921 is the 36.5 millimeter cushion case driver's watch with the dial rotated 45 degrees so the crown sits at 1 o'clock and the watch reads naturally when the wrist is angled on a steering wheel. The Cornes de Vache 1955 is the manually wound chronograph at 38.5 millimeters with the sculpted lugs that give it its name.

Métiers d'Art

The artistic crafts line, built around the four traditional dial decoration techniques the brand has preserved across centuries: engraving, enameling (grand feu, cloisonné, and champlevé), gem setting, and marquetry. The cases are typically 40 millimeters in 18 karat gold or platinum, and most Métiers d'Art references run a time only caliber under the dial because the dial itself is the centerpiece. Production is limited and many references are released in series of a few dozen pieces.

Égérie

The women's collection. The case is offset slightly from center to accommodate a moon phase display in a unique 12 position layout, with dials decorated in pleated motifs inspired by haute couture and case sizes around 35 millimeters. Available in 18 karat gold or steel, with quartz, automatic three hand, and moon phase references.
