Strap for Big Crown Royal Flying Doctor Service Stainless Steel / Black / Bracelet

The lug width is 22mm, the distance between the spring bar holes where the strap attaches. This width is specific to the Big Crown 44mm model and ensures proper visual proportions. You can verify it by measuring the distance between the two protruding metal pins on the case.

The choice depends on your intended use. A vegetable-tanned leather strap emphasises the watch's aviation heritage and develops a natural patina over time. Alligator leather adds formal elegance. NATO straps or rubber maintain the tool watch character whilst offering practical functionality. Milano Straps recommends trying different 22mm-compatible options to find your personal preference.

Using a spring bar tool, gently push the clip inside the pin to release it. The new strap is inserted by threading the pins through the case lugs. Professional intervention is unnecessary; it's a straightforward operation requiring only a minimal tool available online. Milano Straps includes guidance with every purchase.

All straps with a 22mm lug width are compatible. Milano Straps offers a dedicated collection at this width: leather, NATO, rubber, cordura, silicone. Each item is tested to ensure perfect fit to the case lugs without forced adjustments.

A vegetable-tanned leather strap lasts approximately 3–5 years with regular use, longer if worn intermittently. Longevity depends on humidity, frequency of wear and maintenance. Excessive water exposure shortens its lifespan. Milano Straps sources leather selected for durability, and strap replacement remains economical and straightforward compared to other accessories.
