Strap for BR 03-94 Aéro GT Chronograph

The Bell & Ross BR-03 BR0394-SC/SCA is fitted with a 24mm lug width. This measurement represents the diameter of the attachment pins and is essential for purchasing compatible aftermarket straps. The lug width can be verified using a digital calliper or by manually measuring the distance between the two pins protruding from the case at 12 and 6 o'clock.

For the BR0394-SC/SCA we recommend glossy alligator straps for formal settings, vegetable-tanned calf leather for versatile daily wear, or NATO cordura straps for an avionic aesthetic. The choice depends on primary use: dark brown alligator emphasises formal elegance, calf leather adapts to every occasion whilst developing personal patina, NATO straps echo the military heritage of the design.

To change the strap you will need a spring bar tool (available from watch retailers) or a blunt knife tip. Insert the tool into the small hole beneath the lug, gently push outward to release the pin, and extract the lug. The procedure is reversible: the pins must be reinserted into the new strap's housing and locked firmly. If you lack experience, we recommend having the operation performed by a professional watchmaker.

Yes, any strap with a 24mm lug width is compatible with the BR0394-SC/SCA. The aftermarket offers a wide selection of materials and finishes: from alligator to calf leather, from ostrich skin to NATO fabric straps. Artisan leather straps allow further customisation such as choice of hide, thread colour and engraved initials. Always verify that the new strap is fitted with a <a href="/pages/termine-glossario/deployante">deployante</a> compatible with your lug width.

The durability of a leather strap depends on tannery quality and usage patterns. A superior-grade alligator strap lasts 4-6 years with routine care. Vegetable-tanned calf leather achieves 3-5 years, developing patina and micro-cracking that enhance character. Longevity is extended if the strap is not continuously exposed to moisture, intense heat, or repeated friction. The Casati Milano atelier provides an 18-month warranty on bespoke straps and offers repair and reconditioning services to extend your accessory's lifespan.
