Strap for Lange 1 Tourbillon Perpetual Calendar Handwerkskunst

The lug width of the A. Lange & Söhne Lange 1 720.048 is precisely 22 millimetres. This dimension is standard for this model and represents the authentic reference point for high-end straps. To verify it accurately, insert a digital calliper between one lug and the other at the crown, never at the top of the case.

For the Lange 1 720.048 in platinum, alligator leather remains the classical and most harmonious choice: its geometric grain and patina over time create a natural pairing with the precious metal. Shell cordovan represents an extraordinary alternative with internal luminosity and visual depth. Vegetable-tanned calf leather offers Germanic elegance and contemporary sustainability, developing a patina that dialogues with platinum over the years.

Strap replacement requires a specialised tool (spring bar tool or fork screwdriver). Position the watch on a soft surface, locate the lugs, and gently push the spring bar outward to extract the fixing pin. Once the lugs are free, slide out the old strap and insert the new one, locking the pin securely once more. If you are not confident, contact us for rapid replacement service.

Absolutely. A high-quality aftermarket strap at 22mm is entirely compatible with your Lange 1 720.048. It is essential to select a maker who understands the proportion and nobility of leather, as a timepiece of this calibre deserves exceptional materials. Milano Straps offers artisanal 22mm straps crafted with premier-grade leather (alligator, shell cordovan, vegetable-tanned calf).

Leather strap longevity depends upon construction quality and usage pattern. An artisanal strap realised with noble leather (alligator, shell cordovan) and excellence in stitching guarantees between 5 and 8 years of daily wear without compromise. Casati Milano provides an 18-month warranty against manufacturing defects and recommends periodic stitching inspections every 2–3 years to extend longevity. The patina developed on the leather over time represents an aesthetic enrichment and temporal testimony of the object.
