This may be the best watch band I have worn yet, hands down. The leather strap is thin and surprisingly supple, bordering on downright stretchy, and I find I can get a nice tight fit that doesn't seem to cut into my arm over time like other materials. It hungrily soaked up some leather conditioner I like, and now after just a few applications it feels quite smooth and soft, while still clinging tightly to my arm. No slip! I wear a "working watch" so to speak so we'll see how the material holds up long-term, but I do intend to take care of this band on account of the great fit and feel. The band was paired and easily installed to an ordinary old Citizen ECOdrive using nothing-special pins, all thanks to the simple NATO style strap system. A perfect match for this material it seems.
