3.1 Configuració de l'hora
- Pull the crown (middle knob on the right side) out to position 2 (the furthest position). The second hand will stop.

Note: Avoid setting the date between 9 PM and 3 AM, as this may interfere with the date change mechanism.
4. Instruccions de funcionament
4.1 Ús del cronògraf
The chronograph function allows you to measure elapsed time. The watch features three sub-dials for chronograph measurements: a 60-second counter, a 60-minute counter, and a 24-hour indicator (or small seconds, depending on the specific movement). The large blue second hand is the chronograph second hand.
- Inici: Press the upper pusher (button A) to start the chronograph. The large second hand will begin to move.
- Atura: Press the upper pusher (button A) again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
- Restablir: After stopping, press the lower pusher (button B) to reset all chronograph hands to their zero positions.
4.2 Using the Tachymeter
The tachymeter scale on the bezel can be used to measure speed over a known distance (e.g., 1 kilometer or 1 mile) or to measure production units per hour.
- Start the chronograph at the beginning of the measured event (e.g., when a car passes the starting line).
- Stop the chronograph when the event is completed (e.g., after the car has traveled 1 unit of distance).
- Read the number on the tachymeter scale indicated by the chronograph second hand. This number represents the speed in units per hour (e.g., km/h or mph).
5. Manteniment
5.1 Neteja del rellotge
- Netegeu la caixa i el vidre del rellotge regularment amb un drap suau i sec per eliminar la pols i les empremtes dactilars.
- For the silicone strap, you can use a damp cloth with mild soap and water, then rinse thoroughly and dry completely.
- Eviteu utilitzar productes químics agressius, dissolvents o netejadors abrasius, ja que poden danyar l'acabat o les juntes del rellotge.
5.2 Resistència a l'aigua
Your TW Steel TW938 watch is water resistant to 165 feet (5 ATM). This means it is suitable for everyday use and can withstand splashes, rain, and short periods of recreational swimming. It is no suitable for diving, snorkeling, or high-impact water sports.
- Assegureu-vos que la corona estigui completament empenta abans de qualsevol contacte amb l'aigua.
- No feu funcionar la corona ni els polsadors quan el rellotge estigui mullat o submergit.
- Avoid exposing the watch to extreme temperature changes (e.g., hot showers followed by cold water), as this can compromise the water resistance seals.
5.3 Substitució de la bateria
The watch is powered by a quartz movement, which requires a battery. When the second hand begins to jump in 2-second intervals, it indicates that the battery is low and needs replacement. Battery replacement should be performed by a qualified watchmaker or authorized service center to ensure proper sealing and water resistance.
