FAQ
What is the lug width of the A. Lange & Söhne Lange 1 191.063?
The Lange 1 191.063 features a 20 mm lug width, measured between the two horns of the case at the strap attachment point. This is the measurement to provide when ordering a compatible strap. The buckle or deployant clasp typically adopt a width of 18 mm to ensure proper sliding of the tapered strap.
What is the best strap for the Lange 1 191.063 in rose gold?
For the 38.5 mm rose gold case, Mississippi alligator leather in cognac brown or dark brown is the choice most coherent with the manufacturing and formal character of the watch. Alternatively, polished box-grain calf in midnight blue or bottle green offers a contemporary color contrast much appreciated. It is essential that the buckle or deployant clasp be in 18-karat rose gold to maintain metallic consistency with the case.
How do you change the strap on the Lange 1 191.063?
The strap is removed using a springbar tool — a bifurcated pointed instrument — that leverages the ends of the spring bar hidden in the case lugs. Compress the springbar toward the center and extract the strap laterally. This operation is delicate on a rose gold case: it is recommended to protect the lugs with low-adhesive tape or to entrust the operation to a watchmaker to avoid scratches on the finished surfaces.
Are there aftermarket straps compatible with the Lange 1 191.063?
Yes. Any strap with a 20 mm lug width and standard springbar is technically compatible with the Lange 1 191.063. Milano Straps proposes a selection of 20mm artisanal straps — in alligator, calf, NATO and other fine leathers — crafted with finishes and tolerances suited to the high quality level of the watch. Casati Milano also offers a made-to-measure service with direct leather selection in the atelier.
How long does a leather strap last on an A. Lange & Söhne Lange 1?
A quality leather strap — alligator or vegetally tanned calf — has an average lifespan of 18-36 months with daily use, varying based on perspiration, heat exposure and care. The patina that develops over time on a fine leather is part of its aesthetic value. Casati Milano guarantees its straps for 18 months against manufacturing defects; to extend their life it is advisable to alternate two straps and periodically treat the leather with a neutral balm free of solvents.
