Strap for Tourbillon Pour le Mérite Platinum

The lug width of the A. Lange & Söhne Tourbillon 701.005 is 20 mm. This measurement is taken from the hole of one lug to the hole of the opposite lug and is critical when selecting a compatible strap. Do not confuse the lug (the internal metal portion) with the spring bar slot (the external component that accommodates the strap).

For the Tourbillon 701.005 in platinum, we recommend natural or dyed alligator leather, which harmonises beautifully with the case lines and develops a captivating patina over time. Shell cordovan with vegetable tanning is an excellent alternative for those preferring a slightly stiffer structure and superior initial brilliance. Vegetable-tanned calf leather is ideal if you desire a more intimate texture and soft hand for daily wear.

To change the strap on the 701.005, gently remove the spring bars using a dedicated tool or small nylon lever. Extract the pins securing the spring bars, then slide the old strap downward to release it completely. Insert the new strap from the same direction, ensure the spring bars are perfectly aligned, and reinsert the pins. Verify the strap is securely fastened on both sides before wearing the watch.

Yes, absolutely. A high-quality aftermarket strap, crafted from materials such as alligator, shell cordovan or vegetable-tanned calf, is completely compatible with the 701.005 provided it respects the 20 mm lug width. Choose artisans specialising in luxury straps to ensure construction befitting your watch and longevity over time.

The lifespan of a leather strap depends on usage, leather quality and maintenance. A high-quality alligator or shell cordovan strap, used daily, typically lasts 3 to 5 years before requiring replacement. Vegetable-tanned calf leather may have a slightly shorter lifespan (2–4 years) due to its softer texture. Protect the strap from excessive moisture and occasionally apply a conditioner formulated for aniline leather to extend its life.
