Strap for WW1 90 Grande Date & Reserve de Marche

The lug width of the BRWW190-BL-ST/SCR is 22mm. This measurement refers to the internal distance between the two strap attachment points on the case lugs. Any strap compatible with a 22mm lug width will fit this model perfectly.

For the BRWW190-BL-ST/SCR, we recommend straps in genuine alligator leather (for formal elegance and natural ageing), vegetable-tanned calf (versatility and sustainability), or premium recycled NATO fabric made in Italy (authentic aviator sportiness). Selection depends on intended use: formal wear, daily rotation, or adventure. The functional aesthetic of the Vintage demands natural textures and authentic patina, avoiding glossy or laminated materials.

Strap replacement is accomplished by removing the spring bars using a dedicated strap removal tool. Apply gentle pressure to retract the bar into the lug, extract the original strap, and reinsert the bar correctly into the new strap's slots. Perform this operation on a clean surface under natural light, or entrust the task to a professional to avoid scratching the case.

Yes, absolutely. Any strap with a 22mm lug width is compatible with the BRWW190-BL-ST/SCR. Aftermarket straps offer customisation opportunities: material selection, colour, thickness, and buckle type. Milano Straps provides 22mm straps in various finishes, fully customisable with direct WhatsApp support.

Leather strap longevity depends on usage, climate, and tanning method. Under normal daily-wear conditions (non-extreme use), a quality artisanal strap lasts 3–5 years before showing severe wear. Vegetable-tanned leather ages visibly but maintains structure longer than chrome-tanned alternatives. Alligator, owing to superior density, can reach 5–7 years. Casati Milano's 18-month warranty covers manufacturing defects and material anomalies.
