FLYGRAF AIR & SPACE FORCE GMT WATCHES
POSITION A SCREWED-DOWN POSITION
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.
POSITION B MANUAL WINDING
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.
REFERENCE TIME
MORTEAU, FRANCE 10:10
POSITION D REFERENCE TIME SETTING
To set the reference time, unscrew the crown and then pull it out to POSITION D. The seconds hand is
stopped, allowing you to set the time to the precise second.
Set the reference time using the 24-hour hand that moves in increments of 30 minutes (against the
graduations on the bezel) and the minute hand (against the graduations on the dial) by turning the
crown in either direction.
Setting the reference time also moves the conventional hour hand (local time). For this reason, the ref-
erence time must be set before setting the local time.
LOCAL TIME
NEW YORK, US 04:10
REFERENCE TIME
MORTEAU, FRANCE 10:10
POSITION C LOCAL TIME SETTING
When travelling, to adjust local time only (without affecting the 24-hour reference time display),
unscrew the crown and then pull it out to the first notch (POSITION C).
Set the local time by turning the crown clockwise. The hour hand moves in increments of one hour.
The date is linked to local time and changes automatically when the hour hand passes midnight.
IMPORTANT : If your GMT hand is off by one hour after adjustment, you will need to return to the
time-set position in order to turn the H+M hands again one hour forward then return to the desired
position before screw the crown back on. (This allows the cog to train well and not skip a tooth).
OR
You first index the GMT hand in relation to the number of hours of time difference desired, then set
H+M and GMT will follow.
Push in and then screw down the crown.
POSITION C 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 anti-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.
MAINTENANCE
OF YOUR YEMA WATCH
A YEMA watch requires little maintenance. However, some precautions must be
taken to ensure the durability of your YEMA:
• Ensure that the crown is perfectly screwed down after winding up the movement and/or setting the
time and the date. Once the crown is fully screwed down against the case, your YEMA watch is
guaranteed waterproof.
• Avoid activities that may expose your watch movement to shocks.
• Never use chemicals to clean your YEMA watch. Use a microfibre cloth and wash the metal, rubber,
fabric bracelets and waterproof cases from time to time with a soft brush and soapy water. We
recommend that you do not use abrasive or corrosive products (solvents, detergents, perfume, etc.).
• Always rinse your watch with fresh water after it’s been exposed to salt water.
