Gevril Hudson Yards Chronograph - Diver Watch User Manual

Introduction

Thank you for choosing the Gevril Hudson Yards Chronograph - Diver watch. This timepiece combines Swiss automatic precision with robust diving capabilities. This manual provides essential information for the proper setup, operation, maintenance, and care of your watch to ensure its longevity and optimal performance.

Setup

1. Unboxing and Initial Inspection

Carefully remove your watch from its packaging. Inspect the watch for any protective films on the crystal, case back, or bracelet. Remove these films before wearing. Ensure all components are present and undamaged.

2. Winding the Watch

Your Gevril Hudson Yards Chronograph - Diver watch is equipped with a Swiss Automatic movement (SW500). This means it is powered by the motion of your wrist. For initial setup or if the watch has stopped due to lack of wear, it needs to be manually wound:

1. Unscrew the crown (located at 3 o'clock) counter-clockwise until it springs out to position 1.
2. In position 1, turn the crown clockwise approximately 30-40 times. This will build up a sufficient power reserve.
3. Push the crown back in and screw it clockwise to ensure water resistance.

3. Setting the Time and Date

To set the time and date:

1. Unscrew the crown counter-clockwise to position 1.
2. Pull the crown out gently to position 2. In this position, turning the crown clockwise or counter-clockwise will adjust the date. Adjust the date to the day before the current date.
3. Pull the crown out gently to position 3. In this position, the seconds hand will stop. Turn the crown to move the hour and minute hands clockwise until the date changes to the current date. Continue turning to set the correct time, paying attention to AM/PM (the date changes at midnight).
4. Once the time is set, push the crown back into position 1 and screw it clockwise firmly against the case to maintain water resistance.

4. Bracelet Adjustment

The 316L Stainless Steel bracelet features a dive extension deployment buckle. For proper fit, the bracelet may need to be adjusted. It is recommended to have this adjustment performed by a qualified watchmaker or jeweler to avoid damaging the bracelet or watch.

Operating the Watch

1. Automatic Movement

The Swiss Automatic SW500 movement in your watch is self-winding. It gains power from the natural motion of your wrist. When fully wound, it has a power reserve that allows it to run for a certain period (typically 38-42 hours) when not worn. If the watch is not worn for an extended period, it will stop and require manual winding as described in the Setup section.

2. Chronograph Function

The chronograph allows you to measure elapsed time. It is operated by the pushers located at 2 o'clock and 4 o'clock.

• Start: Press the pusher at 2 o'clock to start the chronograph. The central chronograph seconds hand will begin to move.
• Stop: Press the pusher at 2 o'clock again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
• Reset: After stopping the chronograph, press the pusher at 4 o'clock to reset all chronograph hands to their zero positions. The chronograph must be stopped before it can be reset.

3. Unidirectional Ceramic Bezel

The watch features a unidirectional rotating ceramic bezel. This bezel is designed for dive timing and only rotates counter-clockwise to prevent accidental extension of dive time. To use it:

1. Align the zero marker on the bezel with the minute hand at the start of your dive or event.
2. The minute hand will then indicate the elapsed time against the bezel's scale.

4. Helium Release Valve

The watch is equipped with a helium release valve, typically located on the side of the case. This valve is a feature for professional saturation divers. During prolonged periods in a hyperbaric chamber, helium atoms can penetrate the watch case. During decompression, if the internal pressure is not released, it can damage the watch. The automatic helium release valve allows these gases to escape, protecting the watch from damage. This feature operates automatically and does not require manual intervention.

5. Water Resistance (300m / 990ft)

Your Gevril Hudson Yards Chronograph - Diver watch is water resistant to 300 meters (990 feet). This makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving unless specifically stated. Always ensure the crown is fully screwed down before exposing the watch to water. Do not operate the crown or pushers while the watch is submerged or wet, as this can compromise water resistance.

Maintenance

1. Cleaning

To maintain the appearance of your watch, clean it regularly. Use a soft, damp cloth to wipe the case and bracelet. For stainless steel bracelets, a mild soap solution can be used, followed by rinsing with fresh water and drying thoroughly. Ensure the crown is screwed down before cleaning with water.

2. Storage

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

3. Servicing

Mechanical watches, especially automatic movements, require periodic servicing to ensure optimal performance and longevity. It is recommended to have your Gevril watch serviced by an authorized service center every 3-5 years. This service typically includes cleaning, lubrication, and adjustment of the movement, as well as replacement of seals to maintain water resistance.

Troubleshooting

1. Watch Not Running or Stopping Frequently

If your automatic watch is not running or stops frequently, it may not have sufficient power reserve. Try manually winding the watch as described in the Setup section (30-40 clockwise turns of the crown in position 1). If the issue persists after regular wear and winding, the movement may require servicing.

2. Time Inaccuracy

Minor variations in timekeeping are normal for mechanical watches. However, if your watch is consistently gaining or losing a significant amount of time (e.g., more than +/- 30 seconds per day), it may require adjustment or servicing by a professional watchmaker.

3. Condensation Under the Crystal

If you notice condensation or moisture under the sapphire crystal, it indicates that the watch's water resistance has been compromised. Immediately take the watch to an authorized service center to prevent further damage to the movement.
