Defcon Aviator Bund Strap | American Shrunken Bison | Bourbon

Aviator Bund Strap

The Aviator Bund is a classic look elevated with premium shrunken bison leather, offering a bold yet refined presence on the wrist. The integrated pad adds structure and comfort, while the strap maintains an approximate thickness of 4mm. Pad dimensions measure 50mm in width by 100mm in length.

Aviator Heritage
Originally developed for military pilots, bund straps were designed to protect the wrist from extreme cockpit temperatures and oversized watch cases. The name “Bund” comes from the German word Bund (short for Bundeswehr), referencing the style issued to German military pilots. Today, the design remains an iconic blend of function and vintage aviation style.
