Strap for ProPilot Altimeter Carbon / Meter

The lug width of the Oris ProPilot 01 793 7775 8764-Set is 23 millimetres. This specific measurement is standard for ProPilot models of this generation and ensures robust anchoring between the titanium-carbon case and the strap. Any compatible strap must be manufactured to this exact lug width to avoid mechanical play and maintain proportional aesthetics.

The ideal strap depends on intended use and personal preference. For professional and formal contexts, we recommend superior quality leather such as alligator or vegetable-tanned calf, which convey elegance without compromising the watch's functionality. For operational, humid, or nautical environments, NATO straps in technical fabric or vulcanised rubber offer extreme resistance and practicality. Milano Straps offers bespoke 23mm straps across all these categories.

Strap replacement requires specialist tools: a spring bar tool allows you to compress and release the metal pin securing the strap to the case lugs. Position the watch on a stable surface, insert the tool into the spring slot, push inward to release the pin, then remove the old strap. Insert the new strap (23mm lug width) and verify the audible lock of the mechanism. Never force tools: precise, controlled movement preserves case finishing.

Yes, any strap with a 23-millimetre lug width is fully compatible with the Oris ProPilot 01 793 7775 8764-Set. Milano Straps offers a specialised collection of 23mm straps in premium leather (alligator, calf), tactical NATO, and technical rubber, all handcrafted according to aviation-grade quality standards. Both standard models and custom bespoke designs are available through the Casati Milano atelier.

Leather strap longevity varies based on material quality, frequency of use, and environmental exposure. A premium leather strap (alligator, calf) under ordinary conditions typically lasts 3–5 years. Vegetable-tanned leather develops authentic patina over time, increasing aesthetic appeal. Prolonged exposure to humidity, chlorine, or ultraviolet rays accelerates ageing. Periodic maintenance with specialised conditioning creams and rotation with alternative straps significantly extends service life.
