Strap for WW1 97 Reserve de marche Heritage

The lug width of the Bell & Ross Vintage BRWW197-HER-ST/SCR is precisely 20 millimetres. This measurement represents the distance between the two integrated lugs of the case and determines strap compatibility. It is essential to measure with precision using a calliper, excluding any decorative protection, as even half a millimetre of deviation can compromise strap fit and cause lateral movement.

For the BRWW197-HER-ST/SCR, alligator leather represents the premium choice: its natural grain dialogue elegantly with the square geometry of the case, whilst developing authentic patina over time. Alternatively, shell cordovan offers formal elegance and dense, almost wooden tactile qualities. For a sportier approach, vegetable-tanned calf leather combines nobility with daily versatility. NATO straps in cordura remain the most technical and interchangeable option.

Strap replacement requires a dedicated spring bar tool. Gently insert the tool beneath the metal pin (spring bar) supporting the strap in the case lug, applying light pressure to retract the internal spring. The pin will compress, allowing old strap extraction. Repeat on the opposite side. When inserting the new 20mm strap, ensure the pins fully penetrate the lugs and the strap is perfectly centred before releasing spring bar tool pressure.

Yes, provided the strap is specifically designed for the 20mm lug width. Milano Straps offers compatible artisanal straps online, crafted in various materials (alligator, cordovan, calf, NATO) and customisable in length, initials and stitching type. To ensure maximum quality and compatibility, verify technical specifications and, if desired, request personalised consultation with the Casati Milano atelier.

The lifespan of an artisanal leather strap depends on multiple factors: frequency of wear, leather type (alligator and shell cordovan outlast standard calf), climate conditions and maintenance. A vegetable-tanned calf strap worn daily lasts approximately 3-4 years before showing significant wear. Alligator and shell cordovan can exceed 5-6 years maintaining excellent aesthetics. Milano Straps guarantees 18 months on custom straps realised at the Casati Milano atelier, during which support and corrections are managed directly with the craftsman.
