Strap for Grand Lange 1 Yellow Gold / Champagne

The lug width of the A. Lange & Söhne Lange 1 reference 115.022 is 22mm. This measurement represents the distance between the two lugs (the protruding elements from the case that accommodate the strap). To verify this, place a ruler perpendicularly between the inner edges of the lugs: it must measure exactly 22mm. It is essential to confirm this measurement before purchasing a compatible strap, as even a 1mm variance would compromise installation and strap stability on the wrist.

The ideal strap for the Lange 1 115.022 depends on usage and personal preference. For Fine Watchmaking, alligator represents the canonical choice: the geometric grain pattern reflects the constructive rationality of the watch and the texture evokes the modular precision of the movement. Shell Cordovan is an extraordinary alternative for those who appreciate an evolving patina: over time it develops remarkable chromatic depth. Vegetable-tanned calf offers versatility, whilst a yellow gold deployante clasp completes the selection by ensuring stability and aesthetic cohesion between strap and case.

Changing the strap on the Lange 1 115.022 requires specific tools: a spring bar tool and a stable work surface. Position the watch on a change base, access the two small lugs from the exterior, introduce the spring bar tool into the horizontal hole to compress the spring bar and gently withdraw the obsolete strap. Insert the new 22mm strap by aligning the holes with the lugs and press until you hear the click of the spring bar repositioning. If you do not possess the tool, Casati Milano offers the strap change service at the atelier by appointment.

Any strap with a 22mm lug width is compatible with the Lange 1 115.022. On milanostraps.it you will find a selection of handcrafted 22mm straps made from alligator, shell cordovan, vegetable-tanned calf and other materials. Always verify that the specific strap is equipped with a spring bar or that you have a compatible spring bar available. For a bespoke solution, Casati Milano will create a custom 22mm strap following your aesthetic project vision.

The longevity of a leather strap depends on material quality, tanning method and intensity of use. A handcrafted alligator or shell cordovan strap typically lasts 5-7 years of daily wear before replacement is necessary. Vegetable-tanned calf, being more delicate, has a slightly shorter lifespan (3-5 years). These timeframes extend considerably if the strap is used occasionally. Casati Milano provides an 18-month warranty on manufacturing defects and can consult you on maintenance and longevity according to your specific usage pattern.
