Frequently asked questions

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

The lug width of the Bell & Ross BRX1-CE-TI-REDII is 24mm. This measurement is specific to the large-format Instruments collection models and is determined by the position of the attachment pins on the case. To verify compatibility, measure the horizontal distance between the two lugs without adding margins.

Which strap is most suitable for the Bell & Ross BRX1-CE-TI-REDII?

The Bell & Ross BRX1-CE-TI-REDII accommodates various strap options depending on usage. For refined aesthetics, we recommend African alligator or vegetable-tanned calf leather. For a sport-oriented approach consistent with its aviation heritage, technical rubber is the most natural choice. NATO straps in cotton provide an informal option perfect for daily wear.

How do you change the strap on this watch?

To change the strap on the BRX1-CE-TI-REDII, use a spring bar tool (T-shaped or pronged) to gently push the lateral attachment pins. Extract the pin from its seat, remove the old strap and insert the new one by aligning the holes with the pins. This model presents no complications thanks to its straightforward construction.

Which aftermarket strap is compatible with the Bell & Ross BRX1-CE-TI-REDII?

All straps with a 24mm lug width are compatible with the BRX1-CE-TI-REDII. You can choose from the MilanoStraps collection dedicated to 24mm models, designed and crafted for large chronographs. Verify that the strap ends do not interfere with the chronograph pushers.

How long does a natural leather strap last on a chronograph like this?

A strap in vegetable-tanned leather, worn regularly with moderation and subjected to ordinary maintenance (light cleaning, occasional conditioning), lasts an average of 3-5 years. African alligator is more durable and can exceed 5 years. Longevity depends on intensity of use and exposure to water and humidity. Technical rubber offers superior longevity in extreme environments.
