The Oris Big Crown ProPilot Calibre 114 is a 44 mm stainless steel chronograph with a modern interpretation of aviation watch principles, featuring a high-contrast dial with luminescent indices and shaped hands for readability in low visibility. The proprietary Oris 114 movement includes visible power reserve, 24-hour function, and date indicator. The watch has a 22 mm lug width, suitable for both fabric and leather straps, and represents the contemporary evolution of 1940s pilot instruments.

Frequently asked questions

What is the lug width of the Oris ProPilot 01 114 7746 4164-Set 5 22 15FC?

The lug width of the Oris ProPilot 01 114 7746 4164-Set 5 22 15FC is 22 millimetres. This measurement represents the internal distance between the two lugs of the case and is essential for ensuring compatibility with any aftermarket strap. To verify accuracy, measure the space between the inner edges of the lugs using a digital calliper or rigid ruler.

Which strap do you recommend for the Oris ProPilot 01 114 7746 4164-Set 5 22 15FC?

For the ProPilot 01 114 7746 4164-Set 5 22 15FC we recommend three options based on use: a strap in alligator or calf leather with vegetable tanning for formal contexts, capable of developing a natural patina; a NATO in heavy cotton or technical nylon for daily use and outdoors; a hydrophobic rubber strap for aquatic environments. All available in 22mm size from Milano Straps.

How do you change the strap on an Oris watch?

The strap on an Oris watch is changed using a spring bar removal tool: insert the bifid blade into the lateral spaces of the lugs, gently pushing downwards to release the spring bar pin that secures the strap. Once the old strap is removed, align the holes of the new strap with the lugs and press the pin until fully engaged. Repeat on both sides.

Is the strap from the Oris ProPilot compatible with other 22mm watches?

Yes, the strap from the Oris ProPilot 01 114 7746 4164-Set 5 22 15FC, being 22mm, is compatible with any watch that has the same lug width. However, always verify your watch's measurement before purchase to avoid incompatibility. At Milano Straps you will find a wide selection of 22mm straps suitable for universal use.

How long does a leather strap last on the Oris ProPilot?

A quality leather strap, such as those with vegetable tanning available from Milano Straps, typically lasts 3-5 years of daily wear. Longevity depends on frequency of wear, climatic conditions and maintenance: protecting the leather from excessive moisture, avoiding prolonged exposure to direct sunlight, and periodically applying a natural wax-based conditioner significantly extends its lifespan.
