This is a band we had made; why? because the so-called carbon fiber bands by Hirsch are not and also they have that sticky rubber inside lining which is not what a band is for. The inside should be leather as here to absorb perspiration for a comfortable fit. Different than the other CF bands except for color it is black and here has a blue hue due to lighting - It is really and incredible woven nylon that looks very smart as shown here in the photo. It comes in 18, 20 and now 22 mm made for the more popular size divers like the Seiko and Citizen and others but looks great on an SAR ask for a photo. It is 22.00 + shipping and has a stainless steel buckle - deployment clasp available will fit this if you are interest. Thank you.
