Strap for Day-Date 40 Everose / Slate Ombré

The lug width is 20mm. This measurement is taken between the lateral lugs of the case and is the standard for this category of timepieces. A 0.5mm error would result in a strap that is either too loose or too tight.

Authentic American alligator is the most noble choice—the natural irregular grain highlights the warm-toned Everose gold case. Alternatively, vegetable-tanned calf leather offers a uniform texture and contemporary profile. Japanese shell cordovan represents the minimalist option with exceptional durability.

Strap changing requires a specific tool (spring bar tool) to open the small lateral springs of the lug. This is a delicate operation to avoid damaging the sapphire crystal. We recommend consulting an experienced professional or trusting a specialist atelier such as Casati Milano.

Yes, provided it is specifically crafted for 20mm lugs. A high-quality artisanal strap, made from alligator or vegetable-tanned calf leather, guarantees durability and aesthetics consistent with the watch's status.

Durability depends on material and usage: authentic alligator with vegetable tanning resists 5-7 years of daily wear; shell cordovan can exceed 10 years; English calf leather has an average lifespan of 4-5 years. Regular maintenance (gentle cleaner, air drying) significantly extends strap life.
