Runners want to know two things - how far and how fast - and this sport watch from Nike delivers on both counts. A separate speed sensor attaches to shoelaces with a secure clip and elastic strap and transmits data to the watch. This lightweight, durable device is designed to convey speed, accuracy and security through its soft form and its stretched elastic retention system. An angled dot-matrix display can be read while on the move and a stainless steel bezel provides additional protection to the crystal while also functioning as the antenna.
