Strap for Oris ProPilot X 01 400 7778 7158

The ProPilot X features a 20 mm lug width, measured between the centres of the spring bar holes on the case. This width ensures compatibility with a broad selection of straps, from NATO fabrics to structured leather.

We recommend a vegetable-tanned calf leather strap in cognac brown to complement the austere titanium case, or a regenerated textile fibre in military green to emphasise the avionic heritage. Black FKM rubber is ideal for humid environments and demanding operations.

To change the strap, remove the spring bars from inside the case using a dedicated lever tool. Position the new strap and reinsert the spring bars into the lateral holes until fully secured. Verify that the strap exhibits no lateral play.

Yes, any strap with a 20 mm lug width is fully compatible with the ProPilot X. Milano Straps offers a curated selection of aftermarket straps in leather, textile, and rubber, all specifically tested for this measurement.

A quality leather strap with vegetable tanning, worn with regular frequency, maintains structural integrity for 3–5 years before requiring replacement. Patina accelerates naturally, conferring aesthetic character. Wear is accelerated in highly humid environments or prolonged exposure to saline perspiration.
