Master Grande Tradition 5022480— lug 20mm

The Jaeger-LeCoultre Master Grande Tradition ref. 5022480 features a 20mm lug width. This measurement is taken with a millimeter caliper at the internal distance between the two lugs, at the strap attachment point. It is essential to use exactly 20mm to ensure a precise fit without lateral play or tension on the lugs.

For a timepiece in rose gold with minute repeater and tourbillon, a smooth polished or semi-polished alligator strap is the most coherent choice: the uniform grain of the belly complements the case finishes without overpowering them. Alternatively, hand-pulled and hand-polished box calf offers a more understated profile. For color pairings, burgundy, midnight blue, and moss green adapt perfectly to the rose gold of the 5022480.

The strap on the Master Grande Tradition 5022480 is replaced using standard 20mm spring bars. A springbar tool—a fine-pointed instrument—is used to compress the bars and release the strap from the lugs. On a piece of this complexity and value, it is recommended to entrust the operation to a watchmaker or specialized atelier such as Casati Milano to avoid scratches on the rose gold surfaces.

Yes. Any strap with a 20mm attachment is technically compatible with the Master Grande Tradition 5022480, provided the spring bars are of adequate length and the strap profile is correctly shaped for the curved lugs of the model. Milano Straps offers a selection of 20mm straps of artisanal production, with a bespoke option through Casati Milano for those who desire hand-selected leather and custom craftsmanship.

The lifespan of a leather strap depends on the material, craftsmanship, and use. High-quality alligator, with hand finishing and saddle stitching, can last 3 to 5 years with regular use, developing over time a characteristic patina that increases its aesthetic value. Calf leather tends to soften more quickly. Casati Milano offers an 18-month warranty on manufacturing defects on all artisanal straps.
