We started using the Hirsch Performance straps a few years ago for some of our sport watches like the RGM Model 151. We have found that most of our customers love these straps because they are durable, flexible, water-resistant, and most importantly they are very comfortable.

You can order several sizes from our RGM accessories page, and they come standard on many model 151 watches.
