I broke the crappy rep buckle that came with my Sinn U1 so I had to try to find a replacement after almost purchasing a gen strap I decided to try a NATO. I was a little concerned because all the NATO straps look to be very flimsy and look generally poor quality. The first NATO I recieved from Ebay for $10 was just that. Too thin, Akward fit, and seemed to be more the color green than grey which is what I ordered. Then the second one I ordered which was $23 was perfect ($21 shipped for Americans). Perfect thickness, Strap holders and Buckles are incredibly high quality, and it is amazingly comfortable for a NATO. If anyone is looking for a NATO I highly recommend www.holbensfinewatchbands.com/
