On a dive watch the bezel only rotates one way so you will not accidentally turn it while on a dive and extend your time under water. If it is moved the one way bezel only allows you to shorten your time under. (Longer could kill you, Shorter will not)

The automatics are an old and proven system. The solar watches seem to work well. (Wife loves hers 4-5 years old) The kinetic ones seem to have problems last time I checked. Spent several hours doing searches on line to see what problems they were having. Short of it was the generator spins at many thousands of RPM’s and does not last long. They may have improved them but I would go solar between the two.
