YEMA FLYGRAF NAVIGATOR WATCHES

POSITION A MANUAL WINDING
Your Yema watch is equipped with a self-winding mechanical movement, this means it is wound
automatically by wrist movements. To ensure optimum winding, wear your watch daily.
Before you first use the watch or if unworn for a long period of time, you will need to wind it manually
by turning the crown clockwise.
Manual winding is done when the crown is in neutral position. Your watch is equipped with a push
crown.

POSITION B DAY / DATE SETTING
To adjust the Day/Date, pull the crown out to POSITION B. Then and turn the crown clockwise or
counter-clockwise to change the Day/ date setting.
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.

POSITION C TIME SETTING
To set the time, you must first pull the crown out into POSITION C and turn in any direction to set the
correct time. The Perpetual Seconds Hand (sub counter at 9 o’clock) remains stationary to allow the
watch to become synchronized for precise accuracy.

BEZEL
FUNCTION

BEZEL
A tachymeter bezel with calculation rules coupled with logarithmic scales, pilots could use the Flygraf to perform
vital in-flight calculations such as average speed, average fuel consumption of an aircraft, converting nautical miles
to miles, miles to kilometers, etc.

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.
