Strap for BR V1-92 Stainless Steel / Black / Calf

The lug width is 20 millimetres. This dimension is specific to the BRV192-BL-ST/SCA model and represents the width Bell & Ross calibrated to maintain optimal proportions on the 38.50 mm case. When purchasing a strap, ensure the width is precisely 20 mm by measuring the distance between the metal lugs (the contact points with the case lugs). Tolerances must be respected: a 19 mm strap will sit loosely, whilst a 21 mm strap will be difficult to insert.

The choice depends on your usage context. Alligator leather in dark brown tones (cognac) is the most refined choice, harmonising beautifully with the blue dial and stainless steel case. For those seeking uniform surface and natural ageing, vegetable-tanned calf leather is ideal, developing a patina that mirrors the case. For practicality and stylistic authenticity, a black rubber NATO strap remains a classic option. Shell cordovan, where available, represents absolute excellence in durability and long-term patina development.

Strap replacement requires a spring bar tool or dedicated strap changing instrument. Place the watch on a soft cloth to prevent scratching the stainless steel case. Position the watch securely, then carefully push the spring bar pin from the opposite side until it releases. Remove the old strap and insert the new one, ensuring the spring bars engage correctly on both sides. The operation demands precision; if inexperienced, consult a watchmaker or the Casati Milano atelier for professional assistance.

Yes, quality aftermarket straps in the correct 20 mm width are fully compatible, provided they meet exact dimensional specifications. Artisanal straps from Milano Straps guarantee high-level craftsmanship, available in premium leathers (alligator, calf, shell cordovan) and precise sizing. The Casati Milano atelier also offers bespoke services with personal leather selection, WhatsApp updates, and an 18-month warranty, providing a comprehensive solution for your timepiece.

Durability depends on material and usage frequency. A quality artisanal alligator strap typically lasts 3–5 years with daily wear, developing natural patina. Vegetable-tanned calf leather offers similar resistance with a more uniform surface. Shell cordovan is the most durable material, lasting 5–7 years or longer. Rubber NATO straps maintain their properties for 3–4 years before showing wear. Regular maintenance, including cleaning and conditioning with appropriate products, significantly extends lifespan.
