Strap for BR 123 Sport Heritage

The lug width of the BRV123-ST-HER/SRB is 20 millimetres. This measurement represents the distance between the two attachment points on the case where the strap is fitted. Since the installed case features integrated lugs (non-removable), it is essential to verify that any aftermarket strap has a maximum thickness of 4 millimetres in the lug area to ensure smooth transition without pressing the crystal.

The best strap depends on usage and aesthetic preferences. For a formal-sports profile, genuine alligator offers natural texture and noble aging; vegetable-tanned calf represents the sustainable alternative with deep patina development over time. For recreational activities or humid environments, FKM rubber resistant to water is the most practical choice. All combinations require compatibility with 20mm lug width and maximum thickness of 4 millimetres.

The BRV123-ST-HER/SRB features integrated lugs soldered to the case, which are non-removable. Strap replacement requires no tools: simply detach the lugs from the previous strap and insert the lugs into the slots of the replacement strap. Ensure that the new strap is designed for 20mm lug width and that the lug holes have compatible thickness (maximum 4mm) to prevent case damage.

Any leather, rubber or fabric strap with 20mm lug width is compatible with the BRV123-ST-HER/SRB, provided that the lug has a maximum thickness of 4 millimetres. Milano Straps offers a dedicated collection of straps in alligator, calf, shell cordovan and FKM rubber, all engineered to respect the geometry of the integrated case. It is advisable to choose custom length based on your wrist circumference to ensure optimal comfort.

The lifespan of a leather strap varies based on material and usage. Genuine alligator, if properly cared for (avoid prolonged immersion and dry with soft cloth), can last 3-5 years of intensive daily use; vegetable-tanned calf has similar durability but develops patina more rapidly. The lug area is subject to greater wear; at Milano Straps you can request restoration services or replacement of the worn area whilst retaining the rest of the original strap.
