Reinterpreting the “aesthetic” of NATO


Kajiwara proposes a new two-piece NATO-style strap. Retaining the signature stainless steel keepers characteristic of NATO designs, it is reimagined as a refined strap that blends naturally into everyday wear.
Rather than the traditional pass-through construction, the design has been reworked to allow compatibility with smartwatches such as Apple Watch. It is a piece that brings the functional beauty of military classics to the modern wrist with ease.
The DNA of NATO lives on
Traditional NATO straps are typically made of nylon, but Kajiwara combines water-resistant leather that stands up to sweat and moisture, incorporating elements of NATO functionality into a new form.
Reinterpreting the “function” of NATO


Conventional NATO straps are known for their durability and practicality, most often made from tough nylon. Lightweight, strong, and built to withstand a wide range of conditions, that toughness is part of their appeal. However, Knot has taken on the challenge of reinterpreting NATO through leather.
Soft and supple, the water-resistant leather conforms comfortably to the wrist, offering a warmth and depth that nylon cannot provide. Paired with the stainless steel keepers, it enhances the classic, refined character of military style.
With its water-resistant properties, the strap moves beyond the traditional perception of leather as delicate – achieving both everyday practicality and a polished, sophisticated appearance.
Leather with Water Protection
This water-resistant leather strap is uniquely treated with 3M’s Scotchgard™ Leather Protector as an integral part of the tanning process, ensuring protection runs through the leather rather than being applied to the surface alone.
