Frequently asked questions

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

The lug width is 24 mm. To verify this measurement, measure the internal distance between the two lugs at the ends of the case. This dimension is compatible with a wide variety of quality aftermarket straps.

Which type of strap is best suited for the Bell & Ross Instruments BRX1-CE-TI-RED?

For this technical timepiece, we recommend flame alligator leather (to elevate formality), vegetable-tanned calf (to develop patina over time), tactical NATO fabric (to maintain operational identity), or vulcanised rubber (for humid environments). Your choice depends on context: military, formal business, or sport.

How do you change the strap on the Bell & Ross Instruments BRX1-CE-TI-RED?

Position the watch with the case facing downward on a soft surface. Locate the spring bar retention mechanism inside each lug using a spring bar tool. Gently press the spring on one side to extract the bar, then repeat on the other side. Insert the new bar into the lugs and ensure both ends are properly secured.

Are aftermarket straps compatible with the BRX1-CE-TI-RED?

Yes, quality aftermarket straps designed for a 24 mm lug width are compatible. Always verify technical specifications before purchase. Milano Straps offers compatible straps customisable in leather type, colour, and stitch thread, with the option of bespoke creation at Casati Milano atelier.

How long does a leather strap last on this watch?

A quality vegetable-tanned leather strap on a watch of this weight and typical use has an average lifespan of 3–5 years. Longevity depends on sun exposure, humidity, frequency of wear, and tanning quality. Vegetable leather develops beautiful patina with age. Milano Straps guarantees 18 months on bespoke straps created in-house.
