Strap for Kleine Lange 1 Yellow Gold / Silver

The lug width of the A. Lange & Söhne Lange 1 111.021 is 19 millimetres. This measurement must be calculated from the inside of the left lug to the inside of the right lug, completely excluding the case shoulder. Precision tolerance to the millimetre is essential to ensure a perfect strap fit and optimal optical stability of the case.

For the 111.021 in yellow gold, we recommend alligator in deep brown, which amplifies the warmth of the gold whilst maintaining visual primacy of the dial. Alternatively, vegetable-tanned calf offers a modern foundation with developing patina that creates a personal narrative for your watch. Shell cordovan is ideal for those who appreciate density and durability, particularly on slighter wrists.

Strap replacement requires a spring bar tool or fine-tipped pliers. Position your watch on a soft surface, locate the lateral lugs of the left lug, compress the internal metal support with the tool and gently extract the lug. Repeat for the right lug. Reverse the process to fit the new strap, ensuring that the metal passants are completely inserted into their respective seats.

Yes, any strap with a 19mm lug width is compatible with the Lange 1 111.021. Our artisanal straps are manufactured to precise tolerances to guarantee perfect fit. We recommend verifying that the strap is constructed with quality materials (alligator, calf, shell cordovan) to maintain aesthetic coherence and durability over time.

Leather strap longevity depends on material and usage patterns. Alligator and shell cordovan offer 5-8 years with regular wear and appropriate care. Vegetable-tanned calf typically lasts 3-5 years, but develops patina that increases aesthetic value over time. All our straps are covered by an 18-month warranty against manufacturing defects.
