These were much bigger/wider than expected. 60Please see the photos. I used a small bubble level to make sure it was straight. I wear them every minute around the house. Buy any other brand! You can use the bezel or touchscreen to move through items, and the two buttons on the side to select and navigate. I love the style and the way they fits and feel. The account is more than just a sharing of a long distance bike ride. After playing for short period of time the front (this cover) is pretty warm. Wait for all stations to scan first.
