Strap for Reverso Classic Medium Duetto Stainless Steel / Silver

The lug width of the Jaeger-LeCoultre Reverso Q2578480 is 18 millimetres. This measurement is critical for strap compatibility and must be verified by placing the calliper perpendicular to the case's lateral grooves, excluding the curve. No strap with a lug width different from 18mm will be compatible with this model.

The optimal strap choice for the Q2578480 depends on intended use and personal aesthetics. Mahogany brown alligator represents the pinnacle choice: the regular grain texture and natural luminosity create chromatic harmony with the brushed steel case. For vintage patina, vegetable-tanned calf offers natural ageing. Shell cordovan is an exclusive option for those seeking contemporary gloss and curvature. Casati Milano enables personal evaluation of each option within the atelier.

Changing the Q2578480 strap requires constructive precision. The case's lateral lugs feature grooves where the strap inserts; never employ tools that risk scratching brushed steel. If experienced, utilise a dedicated spring bar tool, inserting the tip into the grooves with controlled pressure. For constructive safety and case protection, we recommend entrusting this operation to a certified watchmaker professional.

Yes, the Q2578480 is compatible with any strap constructed on an 18-millimetre lug. However, not all straps maintain the aesthetic and functional equilibrium of the original design. Casati Milano's artisanal straps are dimensioned and constructed specifically for the Reverso's reversible architecture, ensuring mechanical compatibility and visual harmony. Mass-produced, economical straps risk compromising both aesthetics and rotation functionality.

Leather strap longevity depends on material quality and usage intensity. A high-quality artisanal alligator or vegetable-tanned calf strap typically lasts 5-8 years with moderate daily use. Shell cordovan, due to superior material density, achieves 8-10 years. Ageing is a natural process: leather develops characteristic patina and texture. Casati Milano provides an 18-month warranty against manufacturing defects and recommends periodic maintenance with leather-specific conditioning products.
