Strap for Big Crown ProPilot Calibre 111 Stainless Steel / Grey / Bracelet

The lug width is 22 millimetres. This construction standard accommodates thick-sectioned straps while maintaining correct visual proportions on the 44-millimetre case. Verify the measurement with a digital calliper positioned between the inner edges of the horizontal pins.

For the Oris ProPilot 01 111 7711 4163-Set 8 22 19, we recommend: vegetable-tanned leather for those seeking patina development; polished alligator for formal use; NATO for tactical versatility; rubber for professional environments with elevated humidity. Choice depends on predominant usage and personal aesthetic preference.

Remove the watch from your wrist. Use a spring bar tool to compress the internal horizontal pin and slide the lug out of the lug hole. Repeat on the opposite side. Insert the new strap pins aligning them with the lug holes and compress until they click into position. Verify the strap is secure before wearing the watch.

Yes, completely. Milano Straps manufactures straps bespoke for 22-millimetre lugs. Each strap is constructed with correct spring bars and tested prior to dispatch. You may choose from diverse materials and finishes, all compatible with Oris construction standards.

A quality leather strap, in vegetable tanning, has an average lifespan of 3–5 years with regular use. Longevity depends on exposure to humidity, direct sunlight and maintenance frequency. Periodic applications of conditioning balm significantly extend leather lifespan. NATO and rubber straps have superior durability, 5–7 years.
