Frequently asked questions

What is the lug width of the Bell & Ross Instruments BRX1-CHTB-PG-D?

The lug width of the BRX1-CHTB-PG-D is 24mm. This measurement refers to the internal distance between the two case lugs and is crucial for aftermarket strap compatibility. Always verify this dimension before purchasing a replacement strap.

What is the best strap for the Bell & Ross Instruments BRX1-CHTB-PG-D?

The finest choice for this rose gold tonneau chronograph is first-grade alligator, featuring a consistent grain pattern that amplifies case legibility. Black alligator offers formal contrast, whilst medium brown develops a natural patina over time that harmonises with the warm metal. Alternatively, premium Japanese shell cordovan represents the investment choice for those seeking a strap that evolves chromatically through wear.

How do you change the strap on the BRX1-CHTB-PG-D?

Strap replacement requires a spring bar tool to extract the spring-loaded pins securing the strap to the lugs. Position the tool in the lateral groove of the lug, push inward to compress the internal spring, and the strap will detach. The procedure is reversible: align the new strap with both sides and allow the pin to snap into place. Straightforward operation when executed with care and proper tools.

Which aftermarket straps are compatible with the BRX1-CHTB-PG-D?

Any strap featuring a 24mm lug width is compatible with the BRX1-CHTB-PG-D. Milano Straps offers a comprehensive collection in this size, available in alligator, shell cordovan, vegetable-tanned calf, NATO fabric, and rubber. Customisation includes leather selection, colour, length, and buckle or deployante options.

What is the typical lifespan of a leather strap for a Bell & Ross Instruments watch?

A high-quality leather strap, with proper maintenance, typically lasts 3-5 years of intensive daily wear, or 7-10 years if worn periodically. Alligator and shell cordovan exhibit superior abrasion resistance compared to calf leather. Longevity depends on environmental conditions (humidity, solar exposure, perspiration), cleaning frequency, and correct storage when unworn. Casati Milano provides an 18-month warranty on materials and craftsmanship.
