Strap for WW1 97 Reserve de Marche

The lug width of the Bell & Ross Vintage BRWW197-BL-ST/SCR is 20mm. This dimension corresponds to the width of the spring bar mechanism that secures the strap. To verify it, measure the distance between the inner edges of the two lug pins: you will find exactly 20mm. In the Milano Straps catalogue, all compatible straps are classified specifically for this measurement.

The best strap depends on your intended use and aesthetic preference. For chromatic harmony, a dark blue alligator absorbs the dial colour and creates visual continuity. For sophisticated contrast, dark brown shell cordovan enhances the case's satin finish. For everyday practicality, vegetable-tanned calf leather balances elegance with durability. Structured rubber remains the pure technical choice, as seen in original 1970s aviator watches.

The Bell & Ross Vintage BRWW197-BL-ST/SCR uses a spring bar mechanism housed within each lug. To remove the strap: position the watch with the dial facing down, use a flat tool (spring bar tool) to gently press the small lever on the spring bar, then pull the pin outward. Insert the new strap by aligning the pin with the hole and press until you hear the click of re-engagement. Verify that the spring bar is fully seated on both sides before wearing the watch.

The durability of a leather strap depends on the tanning method and daily usage. Quality artisanal calf leather tanned with vegetable methods, with moderate use and limited water exposure, easily reaches 3-4 years. Alligator and shell cordovan can last 4-6 years due to fibre density. Structured rubber, when protected from prolonged UV exposure, maintains elasticity for 5-7 years. Factors such as perspiration, chlorine and constant humidity reduce lifespan. Milano Straps provides an 18-month warranty on all straps, certifying the quality of craftsmanship and materials.
