Built for Everyday Adventure
Made from premium woven nylon, our NATO straps are lightweight, breathable, and incredibly comfortable to wear throughout the day. The tightly woven material is soft against the skin while being tough enough to withstand everyday use in even the most demanding environments.

Premium Stainless Steel Hardware
Each strap is fitted with brushed stainless steel hardware, providing excellent strength and corrosion resistance. The robust buckle and keepers are designed to withstand years of daily wear while perfectly complementing the rugged appearance of your Seiko Prospex.
Secure NATO Design
The classic NATO design offers an extra level of security compared to conventional two-piece straps. If one spring bar should fail, your watch remains attached to the strap, making NATO straps a favourite among military personnel, divers, and outdoor enthusiasts.
The one-piece construction also makes changing straps quick and easy without compromising comfort.
