DIVE WATCHES

SCREWED-DOWN POSITIONPOSITION A
POSITION B MANUAL WINDING
Your YEMA watch is equipped with a screw-down crown. A screw-down crown ensures
waterproofness by sealing the crown to the case of the watch.
Your YEMA watch is equipped with a self-winding mechanical movement, this means
is wound automatically by wrist movements alone. To ensure optimum winding, wear
your watch daily.
Before you first use the watch or if unworned for a long period of time, you will need
to wind it manually by unscrewing the crown and then turning it clockwise.

RAPID DATE-SETTING
If your YEMA watch is equipped with a date, to adjust the date, unscrew the crown
and pull it out to the second notch. Then simply turn it clockwise until the desired
date appears in the window. During this operation, your watch will keep running.
IMPORTANT: Do not make date adjustments when the time on the watch reads
between the hours of 9:00pm and 3:00am. The reason is that although a date makes
its changeover close to midnight, the gears that make that change happen to engage
quite a bit earlier. It takes extra time to disengage completely in the aftermath.

TIME SETTINGPOSITION D
In order to adjust the time, unscrew the crown and pull it out to the last notch. Then
turn it in either direction until the hands indicate the correct time. The small seconds
hand is stopped during this operation, allowing the time to be set accurately.

As an extra safety measure, YEMA developed a
propietary bezel-lock mechanism in the 1960s,
which is still used nowadays and brings a unique
look to the Superman Collection.
