Strap for Tourbillon Pour le Mérite White Gold Blue

The Tourbillon 701.007 features a lug width of 20mm, which refers to the distance between the spring bars that attach the strap to the case lugs. This is a classic standard size that ensures compatibility with a wide range of aftermarket straps in leather, rubber, and fabric.

For the white gold 701.007, we recommend vegetable-tanned alligator in medium brown or grey vitello calf leather with natural texture. These materials enhance the constructive sobriety and patina of white gold without visual competition. Alligator offers maximum formality, whilst calf guarantees everyday versatility whilst maintaining elegance.

Changing the strap on the 701.007 requires two tools: a spring bar tool for removing the metal pins from the lugs, and manual precision to avoid scratching the white gold. We recommend working on a soft surface such as a leather mat, and ensuring the new strap is dimensioned precisely at 20mm. If you prefer to avoid any risk, Casati Milano offers professional strap-changing service including colour consultation and expert installation.

Yes, the 701.007 is fully compatible with quality 20mm aftermarket straps. The key is selecting materials that respect the model's constructive identity: vegetable-tanned leather (alligator, vitello, cordovan) ensures durability and natural patina development. Avoid synthetic leather or low-quality plated straps that would undermine the sophisticated craftsmanship of the timepiece.

Leather strap durability depends on tanning method and material quality. Vegetable-tanned alligator or vitello lasts approximately 3–5 years with routine maintenance (leather oil applied 1–2 times annually), whilst shell cordovan can last 5–7 years due to its superior natural density. Wear is progressive and controlled: the leather softens and develops a patina reflecting the watch's usage history, consistent with A. Lange & Söhne's philosophy. Casati Milano provides 18-month warranty on manufacturing defects.
