Strap for Khaki Pilot Day-Date Auto 46 Stainless Steel / Black

The lug width (ansa width) of the H64725531 is exactly 22mm. This measurement represents the distance between the two attachment pins and determines compatibility with all aftermarket straps. It is one of the most critical specifications to verify when purchasing a replacement strap.

We primarily recommend vegetable-tanned leather straps in tobacco or cognac tones, which harmonise beautifully with the khaki dial and the natural patina of the steel case. Vulcanised rubber straps are ideal for daily use and humid environments. Textile NATO straps reference the original aviator heritage and offer maximum durability.

Strap change requires a spring bar tool (strap pin extractor), a simple device available at any watch retailer. Position the tool under the metal spring bar attached to the case, push inward firmly to release the spring, remove the pin, take off the old strap and insert the new one by aligning the holes. No watchmaking expertise is required.

Yes, all Milano Straps products in the 22mm category are compatible with the H64725531. Width is guaranteed, and materials are selected to harmonise aesthetically and functionally with the steel case and khaki dial. You may choose from artisanal leather, rubber, NATO and other materials with complete confidence of fit.

A quality leather strap (vegetable-tanned or calf skin) worn daily on a robust aviator like the H64725531 typically lasts 3-5 years, depending on climate and frequency of wear. The patina that develops is desirable and increases aesthetic value. A rubber strap lasts 5-7 years before showing initial signs of ageing, whilst textile NATO straps can last over a decade with minimal maintenance.
