Introduction
Welcome to the user manual for your Longines HydroConquest L3.650.4.56.6 watch. This manual provides essential information on how to set up, operate, maintain, and troubleshoot your timepiece. Please read it carefully to ensure proper use and longevity of your watch.
Product Overview
This image displays the Longines HydroConquest L3.650.4.56.6 timepiece. It features a black dial with luminous hands and markers, three chronograph sub-dials, and a date window at the 3 o'clock position. The watch is encased in a silver-tone stainless steel case with a unidirectional rotating bezel and is paired with a matching stainless steel bracelet.
The Longines HydroConquest L3.650.4.56.6 is a robust and elegant diving watch, designed for both performance and style. It features a precise automatic movement and is built to withstand demanding conditions.
Setup
1. Initial Winding
As an automatic watch, your Longines HydroConquest is powered by the motion of your wrist. If the watch has stopped, gently wind it manually by turning the crown clockwise approximately 30-40 times while it is in its normal, pushed-in position. This will build up a power reserve.
2. Setting the Time and Date
- Unscrew the crown (if it's a screw-down crown) by turning it counter-clockwise, then pull it out to position 2 (first click) to set the date. Turn the crown clockwise or counter-clockwise until the correct date appears.
- Pull the crown out to position 3 (second click) to set the time. The seconds hand will stop. Turn the crown to move the hour and minute hands to the desired time. Ensure you distinguish between AM and PM when setting the date.
- Once the time and date are set, push the crown back into position 1 (normal position) and screw it down tightly (if applicable) to ensure water resistance.
Operating Instructions
1. Using the Chronograph Function
- Start/Stop: Press the upper pusher (button) to start the chronograph. Press it again to stop.
- Reset: With the chronograph stopped, press the lower pusher to reset all chronograph hands to zero.
2. Water Resistance (300M)
Your Longines HydroConquest watch is water-resistant to 300 meters (30 ATM). This makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving. Always ensure the crown is fully screwed down before exposing the watch to water. Avoid operating the pushers or crown while the watch is submerged.
3. Unidirectional Rotating Bezel
The bezel rotates in one direction only (counter-clockwise) to prevent accidental changes to dive time. Align the triangle marker on the bezel with the minute hand at the start of a dive to track elapsed time.
Maintenance
1. Cleaning
Regularly clean your watch with a soft, damp cloth. For metal bracelets, a soft brush with mild soapy water can be used, ensuring to rinse thoroughly with fresh water afterwards. Always dry the watch completely with a soft cloth. Avoid using chemical cleaners or abrasive materials.
2. Storage
When not wearing your watch, store it in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box is ideal for storage.
3. Servicing
For optimal performance and longevity, it is recommended to have your Longines watch serviced by an authorized service center every 3-5 years. This includes checking the movement, seals, and water resistance.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is losing time. | Insufficient power reserve. | Manually wind the watch (30-40 turns of the crown). Wear the watch regularly to keep it wound. |
| Date changes at noon instead of midnight. | Time is set incorrectly (AM/PM). | Advance the time by 12 hours. |
| Water condensation under the crystal. | Crown not fully screwed down, or seals compromised. | Immediately take the watch to an authorized service center. Do not attempt to dry it yourself. |
| Chronograph hands do not reset to zero. | Requires calibration or service. | Consult an authorized Longines service center for adjustment. |
