The Antenna in the Strap
guarantees good reception of the time signal. Even the signal might be distorted during the day by endless commercial and private applications, I never had a problem receiving the time signal at any time. The strap becomes a tad stiff because of the built-in antenna and the manual warns not to bend that strap too much. But in my opinion, it does not compromise the wearing comfort at all. As you can guess from the single hole in the strap, the other end of the strap is a movable deployant claps made of hard plastic. Quite an original idea to solve the antenna problem. The only disadvantage of this solution is the high replacement cost of the strap. An shark skin or Kevlar strap would have done a lot better.
