Strap for Ollech & Wajs Aviation OW P

The OW P has a lug width of 20mm, which is the standard European specification for wristwatches in this dimensional class. To verify compatibility, measure the internal distance between the two lugs: it must be exactly 20mm, measured perpendicularly to the case plane.

This depends on intended use. For authentic aviatory purpose, a robust NATO strap in twill weave (military grey-green) remains the most direct choice. For lasting elegance, crocodile leather with vegetable tanning or English calf leather develop noble patina over time. FKM rubber is ideal for humid and pressurised environments.

The strap is changed using a spring bar removal tool. Insert the flat end of the tool into the small groove positioned beneath the lug, gently pressing downward to release the spring. Repeat on the other side. Thread the new strap following the reverse path, ensuring the springs lock securely in place.

Yes, any strap with a 20mm lug width is compatible, provided there are no structural obstructions (e.g. lateral ledges on the case). We recommend visual verification before purchase. Artisanal straps from Milano Straps are tested for this compatibility.

A quality leather strap with vegetable tanning, used under normal conditions and subjected to minimal maintenance (periodic cleaning, drying after perspiration), typically lasts 3–5 years. Duration increases if worn irregularly and decreases if constantly exposed to extreme humidity or intense perspiration.
