Frequently asked questions

What is the lug width of the Bell & Ross BR-01 BR0194YELLOW?

The Bell & Ross BR-01 BR0194YELLOW features a lug width of 24 millimetres. This measurement represents the distance between the two lateral lugs of the case where the watch strap's spring bars attach. The 24mm specification is standard within the contemporary sports watch segment, ensuring access to a comprehensive catalogue of artisanal and aftermarket straps of certified quality.

Which strap pairs best with the Bell & Ross BR-01 BR0194YELLOW?

For the BR-01 BR0194YELLOW, we recommend alligator leather straps dyed black or navy blue to create elegant contrast with the yellow dial, or vegetable-tanned calf leather in natural or tobacco tones for a minimalist, technical aesthetic. For those preferring chromatic dynamism, burgundy shell cordovan amplifies the visual dialogue. From a sport-oriented perspective, a black rubber strap with diagonal texture maintains the aeronautical heritage whilst ensuring everyday practicality.

How do you change the strap on a watch with 24mm lug width?

To change the strap, utilise a spring bar tool (a specialised implement with flat levers). Position the tool at the extremities of the lug where the spring bar inserts, exert controlled pressure to release the internal spring and remove the pin. Repeat at the opposite side, then extract the previous strap. Align the new strap, insert the spring bar into the first lug hole, then exert compressive pressure to lock the spring into position. Verify secure fastening before wearing the watch.

Is a 24mm aftermarket strap compatible with the Bell & Ross BR-01?

Yes, any strap certified with a 24mm lug width is compatible with the BR-01 BR0194YELLOW. The lateral lugs of the case accept standard spring bars. We recommend, however, verifying that the strap material (particularly if constructed from thick leather) does not exceed the recommended thickness according to the artisanal atelier's specifications, ensuring optimal spring bar seating and eliminating lateral play during daily wear.

What is the lifespan of a leather strap on a sports watch like the BR-01?

A strap crafted from noble leather (alligatore, calf, shell cordovan) subjected to daily wear on a 46mm sports watch such as the BR-01 BR0194YELLOW can maintain structural and aesthetic integrity for 18–24 months before requiring replacement. This duration depends upon exposure to water, sunlight, frequency of use and preventive care. Vegetable-tanned straps develop a fascinating patina over years, whilst industrially-tanned examples retain stable colouration. The Casati Milano atelier guarantees 18 months on its creations and recommends periodic rotation amongst straps to extend longevity.
