Strap for BR 123 Phantom

The lug width of the BRV123PHANTOM is 20mm. This dimension is calculated by Bell & Ross to maintain correct proportions between the case diameter (41mm) and the width of the lugs. To verify strap compatibility, measure the distance between the two lug holes: it must be exactly 20mm.

For the BRV123PHANTOM, we recommend alligator in chocolate brown or charcoal grey for subtle contrast with the black case, or Italian vegetable-tanned calf leather if you desire a living material that develops patina over time. For rugged use, marine-grade FKM rubber maintains the technical character of the watch. All straps must have a 20mm lug width.

To change the strap, use a spring bar tool (lever tool) to push the elastic pin inward toward the lug. This releases the pin from the case hole. Repeat on the other side. Insert the new strap by aligning the holes with the pins and press until you hear a click. Simple operation requiring just a few minutes and care not to scratch the case.

Yes, any strap with a 20mm lug width is compatible with the BRV123PHANTOM. Online you'll find ready-to-ship models, or you can have a custom strap made at Casati Milano atelier, choosing leathers, thread colour, and initials for a completely personalised piece.

A quality leather strap (alligator or vegetable-tanned calf) lasts an average of 4-6 years with daily use, developing characteristic patina. Durability depends on humidity exposure, frequency of wear, and care. An FKM rubber strap lasts longer, 7-10 years, maintaining elastic properties intact. Casati Milano offers an 18-month warranty on all artisanal straps.
