The Heritage

The Vacheron Constantin Patrimony 1110U/000G-B086 is a 42mm white gold timepiece from the Patrimony collection, representing rigorous formal abstraction in haute horlogerie. The watch features a silver dial with applied baton indices, Dauphine hands, and an unadorned bezel. Powered by the in-house caliber 1400 automatic movement with micro-rotor, measuring just 2.45mm thick with approximately 40 hours power reserve, this ultra-flat case sits naturally on the wrist. The lug width is 18mm, precisely proportioned to maintain visual fluidity between case and strap.

FAQ

What is the lug width of the Vacheron Constantin Patrimony 1110U/000G-B086?

The Vacheron Constantin Patrimony 1110U/000G-B086 is fitted with an 18mm lug width. This measurement is taken with a millimeter caliper positioned between the two lugs at the spring bar attachment point, not on the outer edge of the case. An 18mm strap with a tapered end is the correct choice to respect the ultra-flat profile of this reference.

What is the best strap for the Vacheron Constantin Patrimony 1110U/000G-B086 in white gold?

For the Patrimony 1110U/000G-B086 in white gold, alligator belly or hornback leather in midnight blue, bordeaux, or polished black tones is the first choice for consistency with the manufacture's standing. Black or anthracite grey box calf represents the sartorial alternative for formal daily use. In both cases, an 18mm white gold deployant buckle completes the pairing in a way that is consistent with the original case.

How do you change the strap on the Vacheron Constantin Patrimony 1110U/000G-B086?

Strap replacement on the Patrimony 1110U/000G-B086 is accomplished via standard 18mm spring bars. It is advisable to use a dedicated spring bar removal tool with a fine tip, operating carefully to avoid scratching the 18 karat white gold lugs. For safe service on a timepiece of this value, it is preferable to entrust the work to a qualified watchmaker or the Casati Milano atelier during a custom strap mounting service.

Are there aftermarket straps compatible with the Vacheron Constantin Patrimony 1110U/000G-B086?

Yes, 18mm aftermarket straps with straight or slightly curved ends are compatible with the Patrimony 1110U/000G-B086. Milano Straps offers a selection of artisanal 18mm straps — in alligator, calf, and other materials — crafted with proportions and thicknesses suited to the ultra-flat profile of this Vacheron Constantin reference. The attachment is not proprietary, which makes replacement accessible without case modifications.

How long does a leather strap last on a Vacheron Constantin Patrimony?

A quality leather strap — alligator or box calf — on a Patrimony lasts on average between 18 and 36 months with regular use, depending on exposure to sweat, water, and direct sunlight. Casati Milano straps are covered by an 18-month warranty against manufacturing defects. To extend the life of the strap, it is advisable to alternate between at least two straps and avoid contact with perfumes and cleaning agents directly on the leather.
