3. Setup

3.1 Setting the Time

  1. Pull the crown (middle knob on the right side) out to position 2 (the furthest position). The second hand will stop.
  2. Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the desired time.
  3. Push the crown back into position 0 (normal operating position). The second hand will resume movement.

3.2 Setting the Date

  1. Pull the crown out to position 1 (the first click).
  2. Turn the crown clockwise to adjust the date. If the date changes during the day, it means the watch is set for PM. Advance the time by 12 hours.
  3. Push the crown back into position 0.

Note: Avoid setting the date between 9 PM and 3 AM, as this may interfere with the date change mechanism.

4. Operating Instructions

4.1 Using the Chronograph

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.

  1. Start: Press the upper pusher (button A) to start the chronograph. The large second hand will begin to move.
  2. Stop: Press the upper pusher (button A) again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
  3. Reset: 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.

  1. Start the chronograph at the beginning of the measured event (e.g., when a car passes the starting line).
  2. Stop the chronograph when the event is completed (e.g., after the car has traveled 1 unit of distance).
  3. 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. Maintenance

5.1 Cleaning Your Watch

5.2 Water Resistance

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 not suitable for diving, snorkeling, or high-impact water sports.

5.3 Battery Replacement

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.
