Olive Brown with brown stitching. This isn't typical "seabag OD", it's a warm brown with olive undertones.
NATO straps have been complementing the finest working watches for over half a century now. A simple, classic utilitarian strap that works with dive suits and tuxedos.
These NATO straps are made in Horween Chromexcel. I use horse butt, known for tight grain and resistance to wear and tear.
These are a little thicker than nylon, 1.4mm-1.6mm, and may require curved spring bars depending on your watch, which I'll include. They're also long enough to fold back under the rings, but are easily trimmed if that's not your jam (obviously they can't be returned if trimmed).
I wear mine on a Seiko SKX009 literally every day, and it stands up to pool water, salt water, sweat, vomit, and whatever else. No safe queens here, you'll want a new one before it fails. Honestly, I build everything hoping that your grandkids will use it.
All my straps are 21mm, so they fit 20mm and 22mm lugs well. I'll send both sizes of spring bars.
All products are in-stock and will be processed and shipped within 1-2 business days.
