The CWC "Strap, Wrist Watch, Nylon" (the original MOD title for the strap) is the most durable genuine military-issued strap, which is why thousands of grey straps are purchased by the MOD every year.

The CWC strap will keep its shape and less likely to fray at the holes than other commercial straps. It will perform longer under the most arduous conditions and keep its original look for much longer.
