CHRONOGRAPH WATCHES

AB

DATE-SETTING
If your YEMA watch is equipped with a date, pull the crown to POSITION A. Then
simply turn it clockwise until the desired date appears in the window.
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.

TACHYMETER
FUNCTION

The bezel on your watch has a tachymeter function used to measure a speed or a
flow rate using the chronograph function. Select the desired unit of measurement
(metre, kilometre, mile, litre, etc.], activate the chronograph and stop it when the
desired unit is reached. The centre seconds hand indicates the number of units per
hour on the tachymeter scale.
In order to ensure the precision of the tachymeter, the unit of measurement must
be exactly reached. In addition, the time of measurement should not exceed 1
minute and should not be less than 9 seconds.

MAINTENANCE
OF YOUR YEMA WATCH

• 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.
A YEMA watch requires little maintenance. However, some precautions
must be taken to ensure the durability of your YEMA:
