Just so as not to confuse people, I'd like to clear something up.
The crown is off center, at the 4 o'clock position rather than the common 3 o'clock position so that it won't dig into you when you bend your wrist upwards (or downwards, if you wear your watch upside-down as I do). The crown is the knob that you turn to adjust the date/time... the bezel is the ring around the top of the watch that you can turn in one direction and it clicks (its used as I timer... say you're diving at 60 ft, and you only have enough air for 20 min at that depth, and you don't have a dive computer. You line up the marker on the bezel wherever the minute hand is, and use that as a reference point. Or set it 20 min ahead of the minute hand as a count-down timer).
