Strap for Harmony Chronograph Small Model Pink Gold

The Vacheron Constantin Harmony 5000S/000R-B139 features a lug width of 18 mm, measured internally between the cushion-shaped case horns in pink gold. This dimension requires a strap with a tapered shoulder to sit flush against the narrow, slightly curved lugs that characterise this reference.

For this pink gold chronograph, an alligator strap with vegetable tanning is the most coherent choice: the natural grain and developing patina create a refined dialogue with the case. Shades of bordeaux, cognac or tobacco enhance the warmth of 5N pink gold. For less formal use, shell cordovan or vulcanised rubber offer durability and comfort without compromising the character of the watch.

Strap replacement is performed using a fine-tipped spring bar tool, applying gentle leverage on the spring bar housed within the lug. It is advisable to work on a soft surface to avoid scratching the pink gold case. Given the delicacy of the material and the narrow cushion-profile lugs, it is preferable to entrust the first replacements to a watchmaker or specialist atelier.

Yes. Any 18 mm strap with the correct taper is technically compatible. Milanostraps produces bespoke handcrafted straps, selectable by leather type, colour, stitching and buckle, designed specifically for high horology pieces such as this Vacheron Constantin. The quality of materials and artisanal finishing make them indistinguishable — in terms of care — from manufacture straps.

Longevity depends on leather quality and conditions of use. An alligator strap with vegetable tanning, used in rotation with at least one other strap and kept away from excessive moisture and perspiration, will maintain its structure and appearance for 3 to 5 years. Shell cordovan, being denser and more resistant to creasing, can last even longer. The Milanostraps guarantee covers 18 months against manufacturing defects.
