Strap for Big Crown ProPilot Big Day Date Guardian Flight

The Oris ProPilot 01 752 7760 4213-Set features a 22mm lug width, measured between the inner walls of the upper attachment pins on the case. This measurement is compatible exclusively with straps designed for 22mm lug width.

The choice depends on intended use. For refined elegance we recommend alligator with vegetable tanning; for daily reliability and patina development, Italian calf leather in vegetable tanning; for aerial and marine resistance, NATO in regenerated fibres or FKM rubber. Charcoal black remains the most versatile tone.

Strap change requires a spring bar removal tool: work gently from the case sides, extracting the upper pin from each lug using controlled pressure. Align the new strap's holes with the pins, verifying secure engagement. We recommend consulting a qualified watchmaker if you lack experience.

All straps with 22mm lug width are compatible, regardless of material. Milano Straps offers a curated collection of natural leather, technical NATO straps and FKM rubber, all engineered for standard Oris 22mm pin mounting.

A vegetable-tanned leather strap under moderate use lasts 3-5 years before replacement becomes necessary. Frequent exposure to moisture, perspiration and UV radiation accelerates wear. Regular maintenance (cleaning, conditioning with natural oils) significantly extends longevity.
