    I bought this bb gmt watch(pepsi black). They are beautiful!! It came on the steel bracelet band but it wasn’t comfortable on my wrist while climbing. I wrote the company and they were wonderful to immediately send a NATO strap to me. Right now, I have a beautiful watch and two straps that I can wear on different occasions.
