Strap for Heritage Chronométrie Dual Time Bracelet

The Montblanc Heritage 112648 features a 20mm lug width—the distance between the attachment pins on the case. To verify this, remove the current strap and measure the gap between the pin centres using a digital callipers or tape measure. An incorrect measurement compromises strap fit and security.

We recommend an alligator strap with vegetable tanning in cognac or medium brown. The texture of alligator grain and the evolution of patina complement the case's satin finish. Alternatively, glossy black calf intensifies formal occasions, whilst a grey-sand NATO ensures daily practicality without stylistic compromise.

Position the watch on a soft surface. Locate the spring bar pins (small metal rods) at the sides of the case, beneath the lugs. Using a spring bar tool, gently press the pin on one side to release tension, then extract the old strap. Insert the new strap by aligning the lug holes with the pins, and allow the bar to snap into place. Repeat on the other side. A task of minutes, but requiring precision.

Yes, any strap with a 20mm lug width is compatible with the 112648. However, we recommend specialised manufacturers known for artisanal quality: leather quality, deployante precision, and aesthetic coherence guarantee superior fit and longevity compared to generic straps.

A quality leather strap, vegetable-tanned, guarantees 3–5 years of regular wear (5–6 days weekly) before showing structural fatigue. Vegetable tanning involves progressive patination: colour deepens and leather develops character. With proper maintenance (water protection, occasional natural oil conditioning), longevity increases considerably. Technical rubber straps show superior durability but less aesthetic evolution.
