Strap for Lange 1 Timezone Concorso 2015

The lug width of the A. Lange & Söhne Lange 1 116.049 RS is 22mm. This measurement represents the distance between the two spring bar attachments that connect the strap to the case. It is essential to verify this specification before ordering an aftermarket strap, as an incorrect width would result in total incompatibility with the case attachments.

For the Lange 1 116.049 RS in white gold, we recommend in order of prestige: alligator (regular grain, natural patina over time), shell cordovan (mechanical resistance and unparalleled patina development), vegetable-tanned calf leather (chromatic versatility and daily adaptability). Selection depends on intended use: formal for alligator, balanced for cordovan, versatile for calf leather.

The strap of the 116.049 RS is secured to the case via spring bar attachments typically positioned at 12 and 6 o'clock. To remove the existing strap, use a spring bar tool to compress the lateral springs and extract the lug. Once removed, insert the new strap by aligning the lug holes with the pins, then reinserting the spring bars. We recommend entrusting this operation to a certified watchmaker to prevent damage to the case.

Yes, the 116.049 RS is completely compatible with premium aftermarket straps featuring 22mm lug width. Certified brands such as Casati Milano produce bespoke straps specifically designed for this reference, guaranteeing perfect aesthetic proportions and artisanal construction. Technical compatibility is assured, whilst quality and aesthetic execution vary significantly depending on the manufacturer.

A quality leather strap (alligator, premium calf leather, shell cordovan) has an average lifespan of 3-5 years with daily use, extensible to 7-10 years with rotation between straps and appropriate care. Durability depends on frequency of use, exposure to moisture and sunlight, and maintenance practices. Vegetable-tanned leathers tend to develop pronounced patina whilst maintaining structural integrity. Casati Milano provides an 18-month warranty covering manufacturing defects.
