Strap for Big Crown ProPilot Big Day Date Stainless Steel / Black / Bracelet

The lug width of this model is 22 millimetres. This measurement is taken between the lateral lugs of the case and represents the standard for professional tool watches in the 45-millimetre category. Always verify the distance between the case lugs before ordering a compatible strap.

The choice depends on intended use. For formal pairings, we recommend alligator leather with vegetable tanning that softens the austere dial aesthetic. For professional versatility, a NATO in recycled cotton offers practicality and comfort. For dynamic environments, a cold-vulcanised FKM rubber ensures grip and longevity. Each material emphasises different aspects of this timepiece's aeronautical vocation.

Changing the strap on an Oris ProPilot 01 752 7698 4164-07 8 22 19 is straightforward: use a spring bar tool to lift the small metal lugs securing the strap to the case. Once the pins are extracted, the old strap slides away. Insert the new strap beneath the lugs and push them until fully engaged. The operation takes approximately two minutes of careful attention.

Yes, all artisanal straps with a 22-millimetre lug width are compatible with the Oris ProPilot 01 752 7698 4164-07 8 22 19. The case employs standard spring bars, so no proprietary constraints exist. Choosing custom-built straps ensures perfect fit and superior longevity compared to generic products.

A quality leather strap, constructed with vegetable tanning and artisanal finishes, maintains structural integrity for 3–5 years of regular daily wear. Lifespan depends on exposure to moisture, perspiration, thermal variation and maintenance frequency. Treating periodically with natural creams and protecting from standing water significantly extends strap life.
