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

The lug width is 22mm. This measurement refers to the distance between the two lugs (spring bar holes) on the watch case where the strap attaches. Always verify this dimension before purchasing an aftermarket strap to ensure compatibility.

The choice depends on intended use. For aeronautical authenticity and practicality: military-grade polyamide NATO or FKM rubber. For formal elegance: dark brown alligator or vegetable-tanned leather. For daily versatility: calf leather in tobacco or natural brown tones. The grey-silver dial of the ProPilot complements all these options effectively.

Use a spring bar tool or dedicated watch strap removal tool. Position it under the tip of the spring mechanism on the original strap, push upward until the spring retracts, then remove the strap. Repeat on the other side. Insert the new strap by aligning the holes, ensure both spring bars are properly seated. Verify that both lugs are securely anchored.

Yes, provided the strap is specifically dimensioned for 22mm lugs. Quality artisanal straps (Italian leather, alligator, military NATO) are fully compatible with the Oris ProPilot. Ensure the strap features spring bars of equivalent quality to your watch to prevent retention issues.

A quality leather strap (Italian vegetable-tanned leather or alligator) typically lasts 3-5 years with moderate daily use. Longevity depends on moisture exposure, perspiration, UV radiation, and frequency of use. Raw leather straps develop patina whilst remaining functional beyond 5 years. NATO and FKM rubber easily exceed 10 years without significant degradation.
