Geophysic 8018480 (aka: Q8018480)— lug 20mm

The Jaeger-LeCoultre Geophysic reference 8018480 (Q8018480) features a 20mm lug width. This is the internal distance between the lugs, which determines compatible strap selection. All straps with 20mm attachment are technically compatible with this model.

For the Geophysic 8018480, polished alligator leather is the most fitting choice, reflecting the watch's dress watch character. Matte box calf leather enhances its instrumental vocation. For more versatile everyday wear, nylon NATO or vulcanized rubber straps are functional alternatives that respect the spirit of the original 1958 design.

To replace the strap on the Geophysic 8018480, you need a springbar tool and a pointed instrument. By inserting the point into the slot at the lug, you compress the telescopic pin and release the strap. The operation requires care to avoid scratching the polished case surfaces. If you lack experience, it is advisable to contact a watchmaker or the Casati Milano atelier.

Yes, any strap with 20mm attachment is dimensionally compatible with the Geophysic 8018480. Milano Straps offers a selection of artisanal straps produced by Casati Milano specifically designed for high-end watches, with materials and tapers calibrated to respect the proportions of the 39.6mm case.

The durability of a leather strap depends on the material and usage: quality box calf, with proper care, easily lasts 2-3 years of regular use. Alligator is even more resistant thanks to the fibrous structure of its scales. The 18-month warranty against manufacturing defects offered by Casati Milano on every artisanal strap is a concrete indicator of construction quality.
