Frequently asked questions

What is the lug width of the Bell & Ross Instruments BRS-WHGOLD-IVORY_D?

The lug width of the Bell & Ross Instruments BRS-WHGOLD-IVORY_D is 22mm. This measurement represents the internal distance between the two horizontal spring bars that connect the strap to the case. To verify this correctly, use a ruler and measure the space between the centres of the pins: it is essential to ensure that any aftermarket strap is perfectly compatible with this exact measurement.

Which strap is most suitable for the Bell & Ross BRS-WHGOLD-IVORY_D in white gold?

High-quality alligator is the canonical choice for this timepiece. The uniform and satin grain of the leather does not compete with the luminosity of white gold; rather, it enhances it through sober contrast. Shades such as chocolate brown, dark brown or slate grey find their maximum aesthetic expression in this leather. Alternatively, shell cordovan offers rare beauty with a deep patina that develops over time, creating aesthetic dialogue between watch and strap as they age together.

How do I change the strap on the Bell & Ross Instruments BRS-WHGOLD-IVORY_D?

To change the strap, you will need a tool to remove the spring bars. Position the watch on a stable surface and locate the two small circular holes at the ends of the case where the horizontal pins protrude. Insert the tool into the hole and press lightly inward to release the tension of the pin, then remove it completely. Repeat on the other side and the strap will be free to slide out. To install the new 22mm strap, align the holes with the pins and push gently until the pin clicks into position, feeling a slight click of security.

Are there aftermarket straps compatible with the Bell & Ross BRS-WHGOLD-IVORY_D?

Yes, any strap with a 22mm lug width is completely compatible with the BRS-WHGOLD-IVORY_D. Milano Straps offers a dedicated selection of 22mm straps in fine leathers such as alligator, shell cordovan and calf, as well as options in technical rubber and NATO fabrics. All straps are crafted to artisanal standards and customisable in length, initials and stitching thread to guarantee a perfect fit on your wrist.

How long does a leather strap last on the Bell & Ross BRS-WHGOLD-IVORY_D?

The lifespan of a leather strap depends on the intensity of use, the type of leather and environmental conditions. A high-quality alligator strap, with regular maintenance (periodic protection from moisture and direct sunlight), has a longevity of 4–6 years with daily use. Shell cordovan, being denser and more resilient, can last 6–8 years or more. Critical factors are excessive water exposure, heat and constant humidity. An FKM rubber strap, by contrast, has potentially indefinite durability whilst experiencing aesthetic wear (loss of grip, slight loss of opacity) after 5–7 years of intensive use.
