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

The lug width of the ProPilot is 22mm. This measurement is taken between the inner walls of the lugs where the strap secures. Verifying this specification before purchasing an aftermarket strap is critical to avoid incompatibility. A 20mm strap will not fit, whilst a 24mm strap will be unstable and pose a risk of watch slippage.

The optimal choice depends on your intended use case. For formal and urban wear, we recommend vegetable-tanned alligator in burnt brown or black, which develops natural patina over time. For tactical and sports applications, a NATO in grey or navy Cordura offers durability and reversibility. For frequent pilots, black FKM rubber provides grip and thermal resistance. All materials are available in 22mm width through our catalogue.

Strap removal requires a spring bar tool and minimal effort. Place the watch face-down on a soft cloth, locate the small metal pins at each lug, and gently push the pin from one side through using the spring bar tool until it exits completely. Repeat for both lugs. Align the new strap holes with the pins and press the pins back through firmly. Ensure both ends of the pin are fully seated to prevent accidental detachment.

Yes, absolutely. Any 22mm aftermarket strap is fully compatible with the ProPilot provided the lug width specification is respected. Milano Straps offers a comprehensive selection of leather, NATO, and rubber straps, all tested for precision fit and safety. Artisanal straps allow you to personalise your watch's aesthetic according to your style and operational context.

Leather strap longevity depends on daily use intensity and material quality. A vegetable-tanned Tuscan leather strap, used as the ProPilot intends (alternating contexts), typically lasts 3-5 years before requiring replacement. Ageing is not deterioration but enhancement: the leather develops unique patina and texture, increasing aesthetic value. Regular maintenance—gentle cleaning and moderate sun exposure—extends service life. NATO and rubber straps offer greater durability: 5-7 years and 7-10 years respectively, owing to material resilience.
