Authentic VACHERON ET CONSTANTIN Watch Strap for Deployant Clasp – 19 mm

Authentic VACHERON ET CONSTANTIN Watch Strap for Deployant Clasp – 19 mm

Overview

This is an original Vacheron Constantin OEM leather strap for deployant clasp, 19 mm, sourced directly from Switzerland. The strap is a genuine manufacturer part, tanned from black lacquered leather and intended for use with a 16 mm Vacheron Constantin deployant clasp. The lug end measures approximately 19 mm and tapers to approximately 16 mm at the clasp end, placing it squarely in the category of a vacheron constantin 19mm deployant strap. No deployant clasp or buckle is included.

The leather is black with a lacquered finish — a surface treatment Vacheron Constantin has applied to a number of its dress straps across multiple collections, producing a smooth, low-gloss surface that holds its shape against the case. The short piece measures approximately 55 mm and the long piece approximately 80 mm, placing the total usable length at around 135 mm before the clasp — consistent with a medium-to-slim wrist fit when paired with a 16 mm deployant clasp. The strap is marked VACHERON ET CONSTANTIN on the underside.

Condition is graded Excellent in our Condition Grading Scale below. The strap shows no visible signs of wear — the lacquered surface is intact, the stitching (where present) is undamaged, and the leather is not creased at the fold point. No buckle, clasp, or additional hardware is included with this item.

Vacheron Constantin, founded in Geneva in 1755, is among the oldest continuously operating Swiss watch manufactures. The house has used the “VACHERON ET CONSTANTIN” marking — with the conjunction spelled out — on straps and accessories produced primarily during the mid-to-late twentieth century, a period when the manufacture supplied OEM straps for references across its Patrimony, Historiques, and dress watch lines. This strap is consistent in cut and finish with those supplied for slim dress references fitted with 16 mm deployant clasps. Complete Vacheron Constantin dress watches from that era trade between CHF 3,000 and CHF 15,000 at auction depending on reference and condition; OEM straps in new-old-stock condition are increasingly difficult to source separately.

Specifications

The strap is cut from black lacquered genuine leather. The lug width measures approximately 19 mm, tapering to approximately 16 mm at the clasp attachment point. The short piece is approximately 55 mm in length; the long piece is approximately 80 mm. Total combined leather length is approximately 135 mm, exclusive of any clasp. The taper from 19 mm to 16 mm is a fixed feature of the strap’s cut and is not adjustable.

The strap is intended exclusively for use with a 16 mm deployant clasp — it’s not made for a pin buckle; the strap’s proportions are optimized for a folding deployant clasp format. The underside is marked VACHERON ET CONSTANTIN.

Compatibility

This strap is sized for Vacheron Constantin dress watch references with 19 mm lugs and fitted with a 16 mm deployant clasp. The 19 mm lug width corresponds to a number of mid-century and late-twentieth-century Vacheron Constantin references across the Patrimony and Historiques families, as well as several earlier dress references produced before those sub-collections were formally named. Any watch with 19 mm lugs and a deployant clasp rated at 16 mm in internal width can accept this strap, provided the case geometry allows for a straight or gently curved strap end. No modification to the strap is implied or included.
