The ProPilot 01 114 7746 4164-Set 1 22 72FC, seen from the bench

The Oris ProPilot 01 114 7746 4164-Set 1 is a 44mm stainless steel tool watch with an independent 24-hour hand for timezone adjustment. It features the in-house developed Oris caliber 114 movement with essential complications including hours, minutes, small seconds, date, power reserve indicator, and 10 atmospheres water resistance. The 22mm lug width ensures ergonomic balance and versatility. This contemporary evolution of aviation instrument watches from the 1940s prioritizes functionality and readability without aesthetic compromise, with high-contrast luminous indices and matte surfaces to prevent distracting reflections.

Frequently asked questions

What is the lug width of the Oris ProPilot 01 114 7746 4164-Set 1 22 72FC?

The lug width is 22mm. Measure it by placing a calliper between the inside of the lugs, at the shoulder of the case. Correct measurement is essential to ensure compatibility with aftermarket straps.

Which strap is most suitable for the 44mm Oris ProPilot?

It depends on use: alligator leather with vegetable tanning develops colour evolution and sophistication over time; a premium NATO combines tool-watch aesthetics with ecological sustainability; Italian calf ensures comfort during daily wear. Rigid straps are not recommended: on 44mm cases, ductility is priority.

How do you change the strap on an Oris ProPilot?

Using a dedicated tool (spring bar tool), remove the elastic pins from the lugs, slide out the old strap and insert the new one, making sure the elastic pins click into the holes. Proceed slowly, alternating both sides to avoid case distortion. If uncertain, consult a watchmaking service.

Are aftermarket straps compatible with the Oris ProPilot 01 114 7746 4164-Set 1 22 72FC?

Yes, all straps with 22mm lug width are compatible. Milano Straps offers certified selection of leather, NATO and rubber in this size, tested on Oris models. Always verify lug measurement before ordering.

How long does a leather strap last on a tool-watch like the ProPilot?

On aviation watches, the strap undergoes constant mechanical stress. An alligator with vegetable tanning lasts 3-4 years of daily use; robust calf 2-3 years. Longevity depends on frequency of use, climate conditions and maintenance. Six-monthly cleaning and water-repellent treatment extend strap life.
