Dear 142 (L5100) owners!

I'd like to ask the following:

-if you wear the watch on your right wrist, is it easy to operate the turning bezel w/the crown at 10?
-does the bezel have ratchets or just friction control?
-if it has ratchets: 60 or 120? (minute or half-minute step adjustment?)

Thank you for your help, best regards:

Robertus
