Strap for Tourbillon Pour le Mérite Platinum / Black

The lug width of the Tourbillon 711.035 is precisely 19mm. This dimension corresponds to the proportions of the 36.50mm case and ensures a perfect ergonomic fit on the wrist. When ordering a strap, always verify this measurement using a digital calliper positioned perpendicularly to the spring bar seats.

Alligator remains the classic choice for this platinum case, as the natural grain complements the neutral tone without chromatic competition. For high-quality alternatives, vegetable-tanned calfskin (such as Fjord) offers softness and longevity exceeding 10-12 years. Shell cordovan is suitable for those seeking a constructive density between classicism and boldness. Categorically avoid synthetic straps: the 711.035 demands material coherence.

Strap replacement requires a specific tool (spring bar tool with fork ends) to push the pins from their seats. Position the watch in well-lit conditions, support the case from the back with a soft cloth, and gently push the pin until it fully emerges from the opposite lug. Remove the old strap, insert the new one, and reinsert the pin ensuring it is seated symmetrically. A professional watchmaker completes this operation in minutes.

Yes, with constructive awareness. An aftermarket strap from artisanal manufacture—such as Casati Milano—can be highly appropriate if crafted from equivalent materials (alligator, calfskin, shell cordovan). The key is selecting suppliers who understand constructive details: precise 19mm lug width, clasp proportionate to the case's visual weight, and durable tanning. Avoid generic and mass-produced straps.

A high-quality leather strap lasts approximately 8-15 years depending on the tanning method and daily wear. Vegetable tanning (natural tannins) offers greater longevity compared to chrome tanning, and develops a patina that improves aesthetically over time. Moisture and perspiration accelerate wear; to extend service life, store the watch in dry environments and remove it during prolonged water activities.
