Frequently asked questions

What is the lug width of the Bell & Ross Instruments BRSBLCPHSCE?

The lug width of the BRSBLCPHSCE is 20mm. This measurement represents the distance between the centres of the attachment holes on the side of the case. To verify, simply remove the original strap and measure with a calliper the distance between the two side holes: it must be exactly 20mm to ensure compatibility with any aftermarket strap.

Which strap is best suited to the Bell & Ross Instruments BRSBLCPHSCE?

The ideal strap depends on intended use and aesthetic preference. For formal occasions, black or dark brown alligator is recommended, emphasising the aviation-inspired ceramic case design. For daily wear, vegetable-tanned calf offers durability and develops character over time. Those prioritising practicality should consider technical NATO or vulcanised rubber. All materials must feature a 20mm lug width.

How do I change the strap on the Bell & Ross Instruments BRSBLCPHSCE?

Remove the spring bars from the side holes using a spring bar tool or small flathead screwdriver. Press the bar laterally towards the case centre until it releases with a click, then remove the strap. Insert the new 20mm strap by aligning the bar slots with the case holes, then reinsert the bars until they lock with another click. Ensure the strap is securely fastened by gently pulling.

Are there aftermarket straps compatible with the BRSBLCPHSCE?

Yes, all straps with a 20mm lug width are compatible. On milanostraps.it you will find a dedicated collection of 20mm straps in alligator, calf, shell cordovan, NATO and natural rubber, customisable in measurements and details. Every strap is manufactured to precise tolerances and tested on models such as the BRSBLCPHSCE to guarantee perfect fitment and security.

How long does a leather strap last on the BRSBLCPHSCE?

Durability depends on material and usage patterns. Premium alligator or shell cordovan resists 3-5 years of daily wear before requiring maintenance. Vegetable-tanned calf lasts 2-4 years, developing aesthetic patina. Natural rubber withstands 4-6 years of intensive use. To extend lifespan, avoid prolonged moisture exposure, apply nourishing cream every 6-8 months and rotate between multiple straps. Casati Milano atelier offers an 18-month warranty on every bespoke strap.
