Setup

1. Initial Winding

As an automatic watch, your HydroConquest is powered by the motion of your wrist. However, for initial setup or if the watch has stopped, it is recommended to manually wind it.

1. Unscrew the crown (if it's a screw-down crown) by turning it counter-clockwise until it springs out.
2. Turn the crown clockwise approximately 30-40 times. This will build up a sufficient power reserve.
3. The watch will begin to run.

2. Setting the Time and Date

1. Unscrew the crown (if applicable) and pull it out to the first click position to set the date. Turn the crown clockwise or counter-clockwise until the correct date is displayed.
2. Pull the crown out to the second click position 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 differentiate between AM and PM when setting the date.
3. Once the time and date are set, push the crown back in fully. If it's a screw-down crown, gently push and turn it clockwise to screw it back into place, ensuring water resistance.

3. Bracelet Adjustment

The stainless steel bracelet can be adjusted for a comfortable fit. It is highly recommended to have the bracelet adjusted by a qualified watchmaker or an authorized Longines service center to prevent damage to the links or clasp.

Operating Your Watch

Automatic Movement

Your Longines HydroConquest watch is equipped with an automatic mechanical movement. This means it is powered by the natural motion of your wrist. When worn regularly, the oscillating weight inside the watch winds the mainspring, providing continuous power. If the watch is not worn for an extended period, it will stop. Simply wind it manually as described in the "Initial Winding" section or wear it for a few hours to restart it.

Unidirectional Rotating Bezel

The HydroConquest features a unidirectional rotating bezel, designed primarily for diving. It rotates only counter-clockwise to prevent accidental increases in elapsed time.

1. Before a dive, align the bezel's zero marker with the minute hand.
2. As time passes, the minute hand will indicate the elapsed time on the bezel.
3. This feature helps divers monitor their bottom time and decompression stops safely. It can also be used for general timing of events.

Maintenance

Cleaning

To maintain the appearance of your watch, clean the case and metal bracelet regularly with a soft, damp cloth. For thorough cleaning, especially after exposure to saltwater, rinse the watch under fresh running water (ensure the crown is fully screwed down) and dry it with a soft cloth. Avoid using chemical cleaning agents.

Water Resistance

Your watch has a water resistance rating of 300 meters (1000 feet). 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.
• Do not operate the crown or pushers (if any) while the watch is wet or submerged.
• Water resistance is not a permanent condition and may be affected by aging gaskets or accidental shocks. It is recommended to have the water resistance checked annually by an authorized service center.

Regular Servicing

Like any precision instrument, your Longines watch requires periodic servicing to ensure optimal performance and longevity. It is generally recommended to have your watch serviced every 3 to 5 years by an authorized Longines service center.

Avoiding Magnetic Fields

Automatic watches can be affected by strong magnetic fields, which may cause them to run inaccurately or stop. Keep your watch away from strong magnets found in speakers, refrigerators, certain electronic devices, and magnetic closures on bags or wallets.
