Strap for BR 01 97 Reserve de Marche

The BR-01 BR0197-BL-ST features integrated lugs designed for 24mm-wide straps. This measurement refers to the internal space between the attachment pins. Precision is essential when fitting a strap into these integrated lugs, particularly considering the case's square geometry, which does not tolerate construction approximations.

For the BR-01 BR0197-BL-ST, we recommend authentic alligator leather with traditional tanning or shell cordovan: both offer the rigidity necessary to support the integrated lugs and develop patina that emphasises the case's geometric aesthetic. Alternative options include vegetable-tanned calf with natural ageing, coherent with the model's heritage, or fabric NATO straps that reference the aeronautical origins.

The integrated lugs on the BR-01 require external strap changes: place the watch on a soft surface, locate the two lateral pins, and use a dedicated spring bar remover to compress the lower pin. Never force the square case with blunt tools. The new lug must enter the attachments gradually without rotational stress. We recommend this procedure at a specialist atelier, such as Casati Milano.

Yes, but with strict specifications. A generic 24mm aftermarket strap often presents insufficient construction tolerances for the BR-01's integrated square lugs. Select craftspeople who understand aeronautical geometries: stitching must be rectilinear, thickness consistent, and edges must not protrude from the lugs. Our bespoke straps guarantee perfect fit through personalised measurements.

Durability depends on tanning method and usage. Alligator with traditional tanning resists 8-12 years of daily wear if kept dry and water-proofed annually. Shell cordovan achieves 10-15 years of longevity due to natural density. Vegetable-tanned calf ages more rapidly (5-7 years), but the developed patina increases aesthetic value. Casati Milano's atelier guarantees 18 months on all bespoke straps with extended repair possibilities.
