Strap for Big Crown ProPilot Big Date Okavango Air Rescue

The lug width is 20mm, a specific dimension of the ProPilot collection that ensures ideal proportions with the 41mm case. This measurement guarantees superior wrist stability and compatibility with a wide range of artisanal straps.

The best pairing depends on intended use: black alligator for formal contexts, vegetable-tanned calf for those who appreciate natural patina development over time, NATO in polyamide or silk blend for tactical versatility, FKM rubber for aquatic environments or high-humidity conditions.

Obtain a spring bar tool. Insert the tip into the small lateral opening of the lug and lift slightly to push the pin out of its housing. Repeat on the opposite side. Insert the new strap, aligning the pins and ensuring perfect contact without lateral play.

Yes, provided they respect the 20mm lug width. Straps in alligator, calf, NATO and rubber designed for 20mm fit perfectly. Ensure the material and colour harmonise with the avionic aesthetic of the timepiece.

A quality alligator or vegetable-tanned calf strap, with proper maintenance, maintains functional efficiency for 5-8 years. Natural patina develops within the first 12-18 months; over time the leather softens and acquires character. Durability depends on frequency of wear and environment of use.
