Frequently asked questions

What is the lug width of the Bell & Ross Instruments BRX1-WD-TI?

The lug width of the BRX1-WD-TI is 24mm, an unconventional standard typical of professional chronographs and aeronautical instruments. This measurement ensures correct proportions on a 45mm case and allows uniform pressure distribution on larger wrists. Always verify that the strap is specifically 24mm to avoid excessive play or incompatibility with the case lugs.

Which strap is most suitable for the Bell & Ross Instruments BRX1-WD-TI?

Anthracite grey or black alligator is the most coherent choice with the BRX1-WD-TI's identity, enhancing the geometric purity of the titanium case without competing visually with the wood inserts. Alternatively, vegetable-tanned calf leather in black offers a patina that evolves over time. For those prioritising functionality, a black Cordura NATO strap references professional tactical use. Technical FKM rubber is suitable for intense sporting activities.

How do you change the strap on the BRX1-WD-TI?

The strap is changed using a spring bar removal tool to extract the elastic pins securing the strap to the case lugs. Position the tool in the small hole on each side of the case, gently push the pin towards the centre and withdraw the old strap. Insert the new strap by aligning its holes with the pins, then push until a click indicates secure fastening. The procedure takes just minutes and can be performed at home or by a specialised atelier.

Does the BRX1-WD-TI accept compatible aftermarket straps?

Yes, the BRX1-WD-TI accepts any quality strap with 24mm lugs, provided the lug width is precisely measured. Quality aftermarket options, such as those offered by Milano Straps, guarantee noble materials (alligator, calf leather, technical elastomer) and accurate finishing. Always verify that the strap is specifically destined for 24mm size and that the overall length is adequate for your wrist.

How long does a leather strap last on the BRX1-WD-TI?

A quality leather strap (alligator or vegetable-tanned calf) on a BRX1-WD-TI has an average lifespan of 3-5 years with daily use, varying based on sun exposure, humidity and frequency of use. Vegetable tanning develops a noble patina over time. It is advisable to have the strap serviced annually by a specialised atelier, which can renew stitching and apply protective treatments. Milano Straps offers an 18-month warranty on all artisanal straps.
