Master Ultra Thin 1358480— lug 20mm

The Jaeger-LeCoultre Master Ultra Thin 1358480 has a 20mm lug width. This measurement can be determined by placing a caliper between the two lugs of the case at the strap attachment point. Respecting this width is essential to ensure proper fit and to avoid altering the case profile.

For the Master Ultra Thin 1358480, a polished mississippiensis alligator strap represents the most coherent pairing with the watch's formal character. For daily wear, box-calf leather in tobacco brown or black develops a patina that improves over time. Thin technical nylon NATO straps are suitable for casual contexts while maintaining a slim profile at the wrist, consistent with the case's ultra-thin philosophy.

The strap is replaced by removing the two spring bars that secure it to the case lugs, an operation requiring a proper spring bar tool with a fine tip. Given the refined finishing of the lugs, it is recommended to protect the case with a soft cloth during the procedure and to entrust the work to an experienced watchmaker or strap specialist to avoid scratches on the satin or polished surfaces.

Yes. Any strap with a 20mm attachment and straight terminal is technically compatible with the Jaeger-LeCoultre Master Ultra Thin 1358480. On milanostraps.it you will find a selection of artisan 20mm straps in various materials and finishes, crafted with steel hardware that matches the original case chromatically. For perfect fit on the curved lug, a custom terminal can be requested through the Casati Milano atelier.

The lifespan of a leather strap depends on the material and daily use. A quality alligator strap, with proper care, maintains structural and aesthetic integrity for 3-5 years of regular use. Box-calf leather, being more porous, develops a characteristic patina but requires attention to humidity. Milano Straps guarantees its straps for 18 months against manufacturing defects, regardless of the material selected.
