The Nicolas Rieussec 106595, seen from the bench

The Montblanc Nicolas Rieussec 106595 is a chronograph launched in 2008 that honors the inventor of the modern chronograph. The 43 mm stainless steel case houses the Montblanc MB R200 caliber with column-wheel mechanism and single pusher, featuring rotating discs instead of traditional hands. The 20 mm lug width ensures compatibility with specialized 20 mm straps for this iconic timepiece.

Frequently asked questions

What is the lug width of the Montblanc Nicolas Rieussec 106595?

The Montblanc Nicolas Rieussec 106595 features a 20-millimetre lug width. This measurement is crucial for aftermarket strap compatibility: any 20 mm strap will fit perfectly to the case lugs, regardless of material. To verify, use a digital calliper to measure between the two horizontal attachment pins—the distance must be precisely 20 mm.

Which strap is best suited for the Nicolas Rieussec 106595?

For a chronograph of this refinement, top-tier materials include premium alligator and shell cordovan. Tobacco brown alligator or deep burgundy cordovan enhance the technical elegance of the column wheel complication. Alternatively, vegetable-tanned calf leather delivers daily resilience whilst maintaining a refined aesthetic. For dynamic use, a technical NATO or rubber strap preserves legibility of the complex dial without visual distraction.

How do I change the strap on my 106595?

Changing the strap on your Montblanc Nicolas Rieussec 106595 requires a spring bar tool (fork-type instrument), available from any watchmaker. Unlock the horizontal pins on the current attachment, slide off the old strap, re-insert the pins into the new 20 mm strap. If inexperienced, consult a professional to avoid lug damage. Atelier Casati Milano offers strap replacement and customisation services by appointment.

Can I use an aftermarket strap compatible with my 106595?

Absolutely. The Montblanc Nicolas Rieussec 106595, with its standardised 20 mm lug width, is entirely compatible with certified artisanal straps of matching width. Alligator, shell cordovan, calf and rubber straps curated on Milano Straps meet quality standards that respect the aesthetic and functional integrity of a timepiece of this calibre. Aftermarket strap use does not void warranty if installation is executed correctly.

How long does a leather strap last on my watch?

Leather strap longevity depends on material and usage patterns. Premium alligator or shell cordovan, if conditioned periodically (every 6–12 months), maintain structural integrity for 8–12 years. Quality calf leather subjected to daily wear typically lasts 5–7 years before replacement. Humid climates, constant perspiration and aggressive creasing shorten these intervals significantly. Rotating between multiple straps—a practice common among collectors—extends the useful life of each.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
