Strap for Lange 1 Daymatic White Gold / 25th Anniversary

The lug width of the A. Lange & Söhne Lange 1 320.066 is precisely 20 mm. This measurement represents the internal distance between the two lugs that attach the strap to the case. Verifying this dimension is essential before purchasing an aftermarket strap to ensure complete compatibility.

Alligator is the optimal choice for platinum: the fine and regular grain of American alligator creates tonal and formal continuity with the case. Alternatively, vegetable-tanned calf in grey-taupe tones conveys sobriety and develops natural patina over time. Avoid excessive contrast: the Lange 1 demands tonal coherence.

Remove the watch from your wrist and position it with the caseback facing downward. Use a spring bar tool to gently compress the elastic pins holding the strap to the lugs. Carefully remove the old strap, then insert the new one by aligning the pins with the lug holes. Verify that the strap is firmly secured on both sides before wearing the watch.

Yes, any artisanal strap designed for a 20 mm lug width is completely compatible with the 320.066. The 20 mm width is an industry standard for this specific watch. Always confirm that your chosen strap is labelled for 20 mm, not 18 or 22 mm.

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with daily use and regular maintenance. Longevity depends on intensity of wear, climate conditions, and care practices. Vegetable-tanned leathers age gracefully and may last longer, developing an increasingly desirable patina.
