The following Seiko SBND051 watch has a curved glass, and its band is made up of silicon. It has a solar driving system as well as magnetic resistance. You need not remove the watch when going underwater as it has a 200m water resistance and completely suitable for air diving. If it is fully charged, then it will smoothly operate for more than 9 months, which is great. All in all, this watch has everything which you will need, so definitely worth buying!
