Master Grande Tradition 5092420— lug 20mm

The Jaeger-LeCoultre Master Grande Tradition ref. 5092420 is fitted with a 20mm lug width strap. This measurement is taken at the base of the case, at the attachment point between the two lugs, using a millimeter caliper. Compatible straps typically feature a taper to 18mm or 16mm toward the buckle.

For a minute repeater in rose gold such as the 5092420, a polished alligator strap in shades of burgundy, chocolate brown, or black represents the most coherent pairing with the fine watchmaking aesthetic. Box-calf leather is the ideal alternative for daily wear, developing a patina that improves over time. Casati Milano creates made-to-measure straps with straight ends, optimal for this model's lugs.

Strap replacement is accomplished via spring bars inserted through the case lugs. It is advisable to use a dedicated tool (flathead screwdriver or professional spring bar tool) to avoid scratches on the rose gold case. For a watch of this caliber, it is recommended to entrust the operation to a watchmaker or the Casati Milano atelier, where the procedure is performed with care.

Yes: any strap with a 20mm lug width and straight ends is technically compatible with the Master Grande Tradition 5092420. Milano Straps offers a selection of 20mm aftermarket straps in alligator, calf leather, and other materials, crafted artisanally and compatible with this model. The Casati Milano atelier also produces bespoke straps made-to-measure to fit perfectly the curvature of the lugs.

The lifespan of a leather strap depends on material quality, care, and frequency of use. A high-quality alligator strap, if kept away from excess moisture and perspiration and periodically treated with appropriate products, can last 2 to 5 years under optimal conditions. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
