Reverso 3926480— lug 20mm

The Jaeger-LeCoultre Reverso 3926480 is fitted with a 20 mm lug width. This measurement is taken with a caliper positioned between the two lugs on the case at the 6 o'clock side, measuring the internal distance between the horns. This is the correct measurement for selecting compatible straps without lateral play.

For a platinum case with tourbillon, a flat-belly Porosus alligator strap in slate gray, midnight blue, or glossy black represents the most formally appropriate choice. Brown box-calf in dark mahogany is a classic alternative for daily wear. Nylon NATO works for a more contemporary and vintage aesthetic simultaneously.

The Reverso 3926480 uses standard 20 mm spring bars. For replacement, it is advisable to use a fine-tipped spring bar tool with plastic protection to avoid scratches on the platinum lugs. Given the value of this piece, it is recommended to have the strap changed by a watchmaker or at the Casati Milano atelier.

Yes, any strap with a 20 mm lug width and standard spring bar is technically compatible with the Reverso 3926480. Milano Straps offers a selection of artisanal 20 mm straps in alligator, calf, NATO, and other materials, crafted to quality standards befitting the nobility of the platinum case.

The lifespan of a leather strap depends on leather quality, daily use, and exposure to sweat and humidity. An artisanal alligator or box-calf strap, with proper care, typically lasts 2 to 4 years with regular use. Casati Milano offers an 18-month warranty against manufacturing defects on all straps made in the atelier.
