To allow time setting, turn the outer ring to SETUP.
Turn the back case ( green area ) while looking at the dial.
The dial ( minutes ) will follow the movement you do with the back.
Both directions are possible but it is preferable to set counter
clockwise if the time span is important.
Always do this close to a soft surface in case the watch would fall.
When time is set, turn the outer-ring back to LOCK position
