Frequently asked questions

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

The lug width (ansa) of the BRSBLCPHSBR is 20 millimetres. This measurement represents the distance between the two attachment holes on the case and determines compatibility with aftermarket straps. It is essential to verify this specification when purchasing a replacement strap to ensure perfect fit without forcing.

Which strap is most suitable for the Bell & Ross Instruments BRSBLCPHSBR?

The choice depends on intended use and aesthetic preference. Natural African alligator creates a fascinating contrast with the black ceramic and develops patina over time. Vegetable-tanned calf leather offers organic colour evolution. For sports use, FKM rubber or cordura NATO fabric ensures environmental durability. Shell cordovan introduces subtle brilliance. Milano Straps catalogues specific options for this lug width.

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

The process is straightforward: obtain a spring bar removal tool or small flat screwdriver. Position the tool in the small release hole located beneath the case lug. Gently press inward to push the attachment bar out of its housing. Repeat on the other side. Insert the new strap by aligning the attachment bars (20mm) with the case holes and press until fully locked. Avoid forcing movements that could damage the ceramic.

Are aftermarket straps compatible with the BRSBLCPHSBR?

Yes, any strap with a 20-millimetre lug width is compatible with the BRSBLCPHSBR. Milano Straps offers a selection of artisanal straps in alligator leather, calf, shell cordovan, and synthetic materials (rubber, NATO) all dimensioned specifically for this lug width. Compatibility is guaranteed metrically at dispatch.

How long does a leather strap last on the Bell & Ross Instruments BRSBLCPHSBR?

A quality leather strap, treated with vegetable or mineral tanning, typically lasts between 3 and 7 years with daily wear. Durability depends on frequency of use, exposure to moisture, heat and sunlight. Calf leather is less resistant than alligator or shell cordovan. Milano Straps provides an 18-month warranty on straps produced in-house and recommends periodic maintenance with products specifically formulated to maintain elasticity and colour.
