I recently swapped out the original strap that came with my Seiko Alpinist with an OD green NATO strap provided by the company "Crown & Buckle." After a few weeks of use, I just wanted to add my .02 cents that this is the nicest NATO strap I've seen. The finish is heavier and more substantial than I usually see, more like tactical canvas or maybe a heavy seat belt type of material. The metallic hardware is burnished, matte finish and also very robust. I think the price was $34usd total, so on the expensive side for a NATO, but the extra money was well spent for the quality. If you are looking to buy a NATO strap, I highly recommend considering this brand.
