Though developed for British troops in the 70s, NATO-style straps are no longer just for military watches. Pair them with modern chronographs and contemporary divers. Pair them with just about anything, really. Their unique design makes swapping a snap and gives the strap its rugged look. High-quality machine-washable nylon offers unrivaled durability and texture that gets softer with age. Stay true to its soldier roots with khaki or military green, or mix it up with colorful stripes.
