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

The Oris ProPilot 01 114 7746 4164-Set 8 22 19 features a lug width of 22mm. This measurement is taken orthogonally between the inner shoulders of the lugs, positioning a digital calliper on the outer surface of the metal wings and excluding the mounting recess. Accurate measurement is essential to ensure complete compatibility with aftermarket straps.

Three main options are recommended for the Oris ProPilot 01 114 7746 4164-Set 8 22 19: a vegetable-tanned Florentine leather strap (Tuscan cowhide in tobacco brown) for a classic, developable patina aesthetic; a NATO strap in ballistic canvas grey-slate for practicality and interchangeability; a vulcanised rubber strap for marine environments or high humidity. Your choice depends on primary use: recreational aviation, formal daily wear, or scuba diving.

Strap replacement requires a spring bar removal tool. Insert the flat blade gently into the space between the lug and case, aligned with the elastic spring, applying light pressure until the spring retracts. Once one end is freed, extract the spring pins from the opposite lug. Reverse the procedure with the new strap, ensuring the spring is securely seated in both holes and retaining full tension.

Yes, the Oris ProPilot 01 114 7746 4164-Set 8 22 19 is fully compatible with artisanal aftermarket straps provided they feature a 22mm lug width. Specialist manufacturers offer straps in vegetable-tanned leather, shell cordovan, high-grade rubber and technical materials, enabling aesthetic personalisation without mechanical compromise or security concerns.

A high-quality vegetable-tanned Florentine leather strap, constructed from Tuscan cowhide, typically lasts 4–7 years under moderate daily wear, developing a distinctive personal patina over time. Longevity depends on ambient humidity, direct sun exposure and frequency of wear. NATO or vulcanised rubber straps offer superior durability (8–12 years) as synthetic and textile materials experience less biological ageing. Regular maintenance—conditioning with natural waxes, rapid drying after water contact—significantly extends useful life.
