Strap for BR 123 Original Black

The lug width of the Bell & Ross Vintage BRV123BLSTSST is 22 millimetres. This measurement is calibrated to the proportions of the 41-millimetre case and ensures visual and functional harmony between case and strap. To verify compatibility, measure the internal space between the two metal lugs of the case using callipers or a millimetre ruler.

For the BRV123BLSTSST, straps in vegetable-tanned alligator, structured grain calf leather or shell cordovan are recommended. African alligator offers natural texture that creates interesting contrast with the brushed case; calf leather permits a broader colour range; shell cordovan guarantees superior durability. NATO textile straps appear visually incongruous with the aeronautical austerity of Bell & Ross design.

To change the strap, use a spring bar tool by inserting the flat blade into the groove on the internal side of the lug. Press gently downward to release the spring bar, then extract the old strap. Insert the new strap by aligning the holes with the lugs and verify the spring bar clicks firmly into position. Check that the strap is centred and no gaps are visible at the case sides.

Yes, the original strap is removable via standard spring bars. All straps with a 22-millimetre lug width are compatible with the BRV123BLSTSST, including bespoke options. On milanostraps.it you will find a selection of 22mm leather, rubber and textile straps, customisable in length, initials and stitching thread. The Casati Milano atelier produces made-to-measure straps with free choice of leather and an 18-month warranty.

A quality leather strap in alligator or vegetable-tanned calf has an average lifespan of 3–5 years with regular daily use. Durability depends on frequency of wear, climate conditions (humidity, heat, sun exposure) and maintenance. A shell cordovan strap tends to last longer due to greater fibre density. The natural patina that develops is part of the desired ageing aesthetic; when the strap shows structural failure signs (lug loosening, padding tears), replacement is warranted.
