Strap for Lange 1 Timezone White Gold / 25th Anniversary

The A. Lange & Söhne Lange 1 Ref. 116.066 features a lug width of 22 millimetres. This dimension is standard for the model and represents the fundamental parameter for compatible strap selection. To verify the correct measurement, use a digital calliper and measure the internal distance between the two lug pins on the case. Any measurement error will result in installation difficulties and visual discord.

For the white gold 116.066 with smalt dial, we recommend alligator leather with medium grain, preferably in pearl grey or mouse grey tones, finished with vegetable tanning. This combination enhances the metallicity of the case without competing visually with the dial. Alternatively, shell cordovan in sand tones or premium box calf offer material depth and noble ageing. We advise against saturated colours or competitive chromatic schemes: the Bauhaus architecture of the dial requires visual restraint from the strap.

Strap replacement is performed by removing the spring bars. Use a dedicated spring bar tool to compress the small catch that secures the pin inside the case lug. Apply gentle leverage to release the pin, repeating on the opposite side. During this operation, take care not to damage the white gold finish on the lugs. A strap of the correct lug width (22mm) will insert smoothly onto the original pair of spring bars. If you desire a bespoke strap, Casati Milano installs compatible spring bars and ensures precision fitting.

Yes, you may use an aftermarket strap of quality provided it strictly respects the 22 millimetre lug width and is constructed from noble materials. We advise against generic straps as the Lange 1 warrants complements built to elevated manufacturing standards. Casati Milano proposes bespoke straps made to measure, allowing you to select leather directly at the atelier and follow every stage of construction. Artisanal straps guarantee precise compatibility, refined finishes and superior longevity compared to industrial products.

A leather strap of elevated quality—alligator, cordovan, calf—subjected to moderate wear—approximately 3–4 times weekly in formal contexts—has an average lifespan of 8–12 years. Longevity depends on frequency of use, exposure to moisture, buckle type and maintenance. Shell cordovan, due to its natural leather density, tends to outlast other materials. Vegetable tanning ensures aesthetic ageing without structural deterioration. To extend strap life, avoid prolonged water exposure, excessive perspiration and extreme humidity conditions. Casati Milano provides an 18-month warranty against manufacturing defects.
