Frequently asked questions

What is the lug width of the Bell & Ross BR-03 BR0392-ST-G-HE/SCA/2?

The lug width is 24mm. This measurement is specific to the BR-03 family and represents the balance between the square case geometry of the 42mm diameter and the tactile proportions required for a wristwatch. Correct measurement must be taken between the internal edges of the case lugs, in the space dedicated to the strap, excluding the pins.

Which strap is ideal for the Bell & Ross BR-03?

Alligator leather in vegetable tanning or shell cordovan are the most balanced choices to respect the minimalist and instrumental language of this model. Vegetable-tanned calf offers discretion and suppleness, perfect for those who prefer soft elegance. For more dynamic use, a NATO strap in heavyweight cotton remains versatile without compromising aesthetic or constructive integrity.

How do I change the strap on the Bell & Ross BR-03?

The BR-03 uses proprietary integrated lugs, different from standard spring bar attachments. Changing the strap requires precise tools (dedicated pin or small screwdriver) and careful attention to avoid damaging the internal pins within the case. If inexperienced, it is advisable to consult a specialised artisan or the Casati Milano service, which performs the change with attention to the specific tolerances of the model.

Can I use an aftermarket strap on this watch?

Yes, provided the lug width is exactly 24mm. However, the proprietary integrated lugs of the BR-03 require very precise strap construction to ensure centring and stability. Straps crafted bespoke by experienced artisans ensure total compatibility and preserve the watch's design integrity.

How long does a leather strap last on a watch like this?

A high-quality leather strap with vegetable tanning and artisanal stitching can last 3–5 years with moderate daily use. Durability depends on humidity, sun exposure, and frequency of wear. Natural leathers age by developing patina and visual character; if the strap becomes excessively worn, it is simple to replace whilst keeping the case intact for decades.

The next step

The right strap isn't chosen. It is built, together.
