There is an "on" and an "off" position on the back of the Orbital II. You move the red arrow on the propeller to line up with the "on" or the "off" position.
Does anyone know if the "on" position locks the rotor in place, or if the "off" position locks the rotor in place?
The question is when is the rotor "on" and when is the rotor locked down, and therefore "off"?
I am a bit confused, and I'm not sure that the Orbital II works the same way as the Orbital I did, but I just don't know.
By the way, the watch is very comfortable for its size.
