Master 1563480 (aka: Q1563480)— lug 20mm

The Jaeger-LeCoultre Master ref. 1563480 (Q1563480) is fitted with a 20 mm lug width. This measurement should be verified with a digital caliper by measuring the internal opening between the case lugs, not the already-mounted strap. A strap of different width will not fit correctly between the lugs and may damage the spring bars.

For a white gold case with tourbillon, a polished Louisiana alligator strap is the most coherent choice: the reptile texture complements the alternating finishes of the case. Box-calf leather is a more versatile alternative, capable of developing characteristic patina over time. Both options in black or midnight blue enhance the chromatic neutrality of the white gold.

To replace the strap on the Q1563480, a fine-tipped spring bar tool is required to release the spring bars housed in the lugs. Insert the tip into the lateral notch of the bar, compress it, and slide out the strap. The operation requires care to avoid scratching the white gold case: if you are not experienced, it is advisable to consult a watchmaker or the Casati Milano atelier.

Yes. The Q1563480 uses a standard 20 mm attachment with traditional spring bars, compatible with any aftermarket strap of that size. Milano Straps offers a selection of handcrafted 20mm straps in alligator, calf, NATO, and rubber, made with materials and finishes appropriate to the timepiece's level. No case modification is necessary for the replacement.

The lifespan of a leather strap depends on the quality of the leather, frequency of wear, and exposure to sweat and humidity. A high-quality alligator or calf strap, worn with care and rotated with other straps, can last 2 to 5 years while maintaining proper shape and patina. Avoid prolonged contact with water and occasionally apply leather conditioner to significantly extend the strap's life.
