FAQ

What is the lug width of the Bell & Ross BR-03 BR03A-BL-CE/SRB?

The lug width of the Bell & Ross BR-03 BR03A-BL-CE/SRB is 20 mm. This dimension represents the distance between the spring bars that secure the strap to the case. You can verify this measurement using a ruler placed between the inner lugs of the 41 mm square case.

Which strap is recommended for the BR-03 BR03A-BL-CE/SRB?

For the BR-03 BR03A-BL-CE/SRB, premium alligator leather straps are recommended for a formal aesthetic, vegetable-tanned calf for versatile daily wear, or rubber/NATO fabric straps for aviation authenticity. The choice depends on intended use and desired dialogue between the strap and the case's black dial.

How do I change the strap on the BR-03 BR03A-BL-CE/SRB?

To change the strap, remove the lateral case bars using a spring bar tool. The BR-03 utilizes standard spring bars: position the tool in the small lateral case holes and push inward to free the bar, then extract the old strap and install the new one by threading it over the bars in sequence.

Can I use an aftermarket strap on the BR-03 BR03A-BL-CE/SRB?

Yes, you may use quality aftermarket straps provided they conform to the 20 mm lug width and are compatible with the case's standard spring bars. Milano Straps provides a curated selection of 20 mm artisanal straps specifically verified for the BR-03, with customisation options available through the Casati Milano atelier.

What is the lifespan of a leather strap on the BR-03?

The lifespan of a leather strap varies according to material and usage patterns. Premium alligator leather typically lasts 5-10 years with regular maintenance. Vegetable-tanned calf offers similar durability, whilst rubber or NATO fabric straps provide more predictable longevity (3-7 years). All Casati Milano straps include an 18-month warranty.
