Strap for Big Crown ProPilot Calibre 114 Stainless Steel / Grey / Bracelet

The Oris ProPilot 01 114 7746 4063-Set 8 22 19 features 22mm lugs. This specification is standard for the 44mm ProPilot model and allows only straps manufactured for this exact lug width. To verify the measurement, measure the distance between the two anchor pins at the narrowest point of the lug.

Material choice depends on intended use. For elegance and longevity, we recommend alligator with vegetable tanning or English aged calf leather: both develop unique patina over time. For operational contexts or humid climates, premium NATO straps in pre-shrunk fabric offer durability and comfort. FKM rubber is the optimal solution for marine environments or intense activities, ensuring resistance to moisture and chemical agents.

Position the watch on a soft surface to prevent scratches. Use a dedicated spring bar tool to push the pin blocking the strap downward. The pin will retract, allowing you to remove the old strap. Insert the new 22mm strap by aligning the pins with the lateral slots on the case, then push the pin to secure it. Work carefully to avoid scratching the metal around the lugs.

Yes, provided the strap is specifically manufactured for 22mm lugs. The 22mm lug width is not compatible with universal straps (18mm, 20mm, 24mm). Always verify exact strap dimensions before purchase. Our artisanal Milano Straps are specifically crafted for 22mm lug width and guarantee certified fit and quality.

Leather strap durability depends on tanning type and usage intensity. Vegetable-tanned alligator, used in non-marine contexts, typically lasts 8–15 years while maintaining elasticity and aesthetics. Aged calf leather has similar wear patterns, with patina becoming increasingly distinctive. In humid environments or with frequent water exposure, lifespan reduces to 4–6 years. Rubber maintains its properties for 5–10 years before becoming brittle.
