This image displays the Jacques Lemans F-5017B watch, showcasing its round dial with chronograph subdials, luminous hands, and a stainless steel bracelet. The watch features a black bezel with a tachymeter scale.

Setup

Setting the Time

1. Pull the crown out to position 2. The second hand will stop.
2. Turn the crown to set the hour and minute hands. Ensure the 24-hour indicator aligns correctly with AM/PM if applicable (e.g., 6 AM vs. 6 PM).
3. Push the crown back into position 1 to start the watch.

Setting the Date (if applicable)

Note: The provided specifications do not explicitly mention a date function. If your specific model includes a date display, pull the crown out to position 1 and turn it to adjust the date. Avoid setting the date between 9 PM and 3 AM to prevent damage to the movement.

Chronograph Hand Reset

If the chronograph hands (seconds, minutes, 24-hour) do not reset to the 12 o'clock (or zero) position after use, they may need calibration. Consult a professional watchmaker for precise adjustment if this occurs.

Operating the Chronograph

The chronograph function allows you to measure elapsed time independently of the main time display.

• Start: Press the upper pusher (A) to start the chronograph. The chronograph second hand will begin to move.
• Stop: Press the upper pusher (A) again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
• Reset: After stopping the chronograph, press the lower pusher (B) to reset all chronograph hands to their zero positions.
• Cumulative Elapsed Time: To measure cumulative time, stop the chronograph, note the time, then press the upper pusher (A) again to restart. Repeat as needed. Press the lower pusher (B) to reset after the final stop.

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 rates.

1. Start the chronograph at the beginning of the distance (e.g., start of a kilometer).
2. Stop the chronograph when you reach the end of the distance.
3. The number on the tachymeter scale indicated by the chronograph second hand is the average speed per hour.

Maintenance

Cleaning

Wipe the watch case and bracelet regularly with a soft, dry cloth. For stainless steel, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners or abrasive materials.

Water Resistance

Your Jacques Lemans F-5017B watch is water resistant up to 100 meters (10 ATM). This means it is suitable for swimming and snorkeling, but not for diving. Always ensure the crown is fully pushed in before exposing the watch to water. Do not operate the pushers or crown while the watch is wet or submerged.

Battery Replacement

The watch is powered by a quartz movement, requiring a battery. When the battery is depleted, the watch will stop. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.

Storage

When not wearing your watch, store it in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it away from strong magnetic fields, which can affect the accuracy of quartz movements.

Troubleshooting

• Watch not running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
• Time inaccuracy: Ensure the watch has not been exposed to strong magnetic fields. If inaccuracy persists, the movement may require servicing.
• Chronograph hands not resetting to zero: This may require calibration. Consult a professional watchmaker.
• Condensation under the crystal: This indicates a loss of water resistance. Immediately take the watch to a qualified service center to prevent further damage.
