Strap for Heritage Chronometrie Quantieme Annuel Red Gold

The Montblanc Heritage 112535 features a lug width of 20mm. This is an international standard dimension for 40mm watch cases, ensuring balanced proportions between the case and strap.

For a red gold 18k case, the ideal choice is an alligator strap with vegetable tanning, which creates a natural dialogue with the warm tone of the gold. An excellent alternative is vegetable-tanned calf leather in dark colourways (black, medium brown, burgundy). The strap should feature a deployante clasp for comfort and ease of adjustment.

Strap replacement requires a dedicated spring bar removal tool. Place the watch on a soft surface, push the spring bar inward until it disengages from the lug hole, remove the old strap, align the new strap holes with the lugs, and release the spring bar until you hear a click. For red gold cases, we recommend having this operation performed by a specialist atelier.

Yes, any strap with a 20mm lug width is compatible with the Heritage 112535. Ensure the strap thickness does not exceed 4mm in the lug passage area to prevent friction against the case. Quality straps from specialist Italian ateliers guarantee precise manufacturing tolerances.

A premium leather strap with vegetable tanning typically lasts 3–5 years of daily wear, depending on frequency of use, climate, and perspiration levels. Alligator or shell cordovan straps tend to have greater longevity. The natural patina that develops is a characteristic of genuine leather, not a quality defect.
