Strap for BR 123 Sport Heritage

The BRV123STHERSST features a lug width of 20mm, a consolidated standard across the Bell & Ross Vintage collection. Measurement is performed by positioning a calliper between the two case lugs perpendicularly, without including the cheeks. Confirming this dimension before purchasing an aftermarket strap is essential to ensure proper compatibility.

Deep-toned alligator (brown or black) represents the ideal choice to emphasise the avionic aesthetic of the BRV123STHERSST. However, calf leather with vegetable tanning offers a patina that develops character over time, whilst technical NATO and rubber are valid alternatives for robust everyday use. Material selection depends on context: formal elegance demands alligator, lifestyle daily wear favours soft calf or rubber.

Strap removal is performed by gently withdrawing the two lateral spring bars connecting the strap to the case. Use a dedicated spring bar tool to prevent damage. Position the new strap with its holes aligned to the case lugs and reinsert the bars with uniform pressure until the retention click is felt. If uncertain, consult a specialist craftsman such as Casati Milano to ensure correct installation.

Yes, all straps with 20mm lug width are fully compatible with the Bell & Ross Vintage BRV123STHERSST. Milano Straps offers a curated collection of artisanal 20mm straps, customisable in length, initials and stitching thread type. Crafted quality and material selection ensure superior durability and aesthetic compared to standard OEM offerings.

Leather strap longevity depends on material and usage patterns. A quality artisanal alligator or calf, with proper maintenance (avoiding prolonged exposure to moisture, protecting from excessive heat, periodic nourishment with neutral wax), typically lasts 3–5 years of daily wear. Vegetable-tanned leather, owing to its natural composition, ages gracefully, developing patina without rapid degradation. Milano Straps' straps include an 18-month warranty at Casati Milano atelier against manufacturing defects.
