Strap for Reverso Classic Large Monoface Small Seconds Stainless Steel / Silver / Fagliano

The lug width is 20mm. This size is standard for the Reverso at this case diameter (27.40mm) and ensures clean, proportional case lugs. Verify by measuring the internal distance between the inner angles of the spring bars with a digital calliper—it must be exactly 20mm for precise seating without play.

Alligator represents the aesthetic pinnacle for the Q3858523: its regular geometric grain and deepening patina emphasise the case's understated design. Vegetable-tanned leather is a conscious alternative if you desire a material that visibly accumulates daily wear. Shell cordovan introduces elegant undulating texture, whilst silk NATO straps offer tactile lightness ideal for summer.

Use a spring bar tool to remove the pins (lugs) from the side holes of the case. Insert the tool's thin tip into the small notch of the pin and apply gentle upward pressure to release the internal spring. Once the old strap is removed, repeat the process in reverse to install the new 20mm strap—ensure the pins click firmly into position.

Yes, any strap with a 20mm lug width is mechanically compatible. However, construction quality matters significantly: choose vegetable-tanned leather, alligator, or shell cordovan treated with artisanal techniques. Casati Milano manufactures 20mm straps specifically designed for luxury watches like the Reverso, with contoured lugs and deployant clasps that complement the case's elegant proportions.

A high-quality artisan-made vegetable-tanned leather strap, with moderate daily use, maintains structural functionality for 3–4 years. Alligator and shell cordovan offer greater resistance to mechanical wear, potentially exceeding 5 years before requiring reconditioning. The patina that develops is aesthetic—not degradation, but deepening character. Casati Milano provides 18-month warranty against manufacturing defects and accepts revisions at the atelier.
