Strap for BR 123 Original Black

The lug width of the BRV123-BL-ST/SCA is 20mm. This measurement is standard for Bell & Ross Vintage collection and requires precision in identification. You can verify it by measuring the distance between the case lugs with a ruler, or by placing an existing strap into the attachments and assessing symmetry. No tolerance is permitted: only 20mm straps will fit correctly.

Alligator remains the reference for the BRV123-BL-ST/SCA. Its fine, natural grain and absence of artificial effects allow the strap to embrace the wrist with precision without rigidity. Calf leather with vegetable tanning is the ideal alternative, developing a natural patina over time that adds visual character. For a sport-oriented approach, canvas NATO or vulcanised rubber maintain the aeronautical character whilst sacrificing aesthetic refinement.

To change the strap on your BRV123-BL-ST/SCA, equip yourself with a spring bar tool and a stable work surface. Position the watch with the case facing downwards. Insert the flat end of the tool into the lateral opening of the lug, gently pushing the pin inwards until it clicks. Repeat for the other pin, remove the old strap and insert the new one, aligning the holes with the pins. Verify that the strap adheres uniformly to the case.

Yes, but with precise conditions. Only straps with 20mm attachments are compatible with the BRV123-BL-ST/SCA. Always verify that the strap is specifically declared for this lug width. Avoid generic straps that may not offer the millimetre precision required to seat correctly in the attachments. Custom straps from specialised artisans guarantee perfect fit and longevity.

Durability depends on material and treatment. A quality alligator with vegetable tanning, used daily, typically lasts 3–5 years before requiring maintenance or replacement. Calf with vegetable tanning develops a rich patina but may wear slightly faster, maintaining a lifespan of 2–4 years with regular use. Climate conditions, humidity and frequency of use influence longevity. A bespoke strap with protective finishing extends useful life significantly.
