1. Introduction
This manual provides essential information for the proper use, care, and maintenance of your Gevril Yorkville Swiss Automatic Watch, Model 48604-4. Please read these instructions carefully to ensure optimal performance and longevity of your timepiece.

The Gevril Yorkville 48604-4 is a Swiss automatic watch featuring a 43mm stainless steel case, a navy blue dial, and a genuine Italian blue leather strap. It is equipped with a Sellita SW200 Swiss Automatic movement and is water-resistant to 200 meters (20 ATM).
2. Setup and Initial Winding
Your Gevril automatic watch is powered by the motion of your wrist. Before wearing it for the first time or after a period of inactivity, it requires initial winding.
- Unscrew the Crown: Locate the crown on the right side of the watch case. Gently unscrew it counter-clockwise until it springs out to position 1.
- Manual Winding: In position 1, turn the crown clockwise approximately 30-40 times. This will provide sufficient power reserve to start the movement.
- Set the Time: Pull the crown out to position 3. Turn the crown clockwise or counter-clockwise to set the hour and minute hands.
- Set the Date: Push the crown in slightly to position 2. Turn the crown clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement. If the current time falls within this period, set the time outside this range, adjust the date, then reset the time.
- Secure the Crown: Once time and date are set, push the crown back into position 0 and screw it clockwise firmly against the case to ensure water resistance. Do not overtighten.
Once wound, the watch will continue to operate as long as it is worn regularly, typically for 8-12 hours a day, or kept on a watch winder.
3. Operating Your Watch
3.1 Automatic Movement
The Gevril Yorkville 48604-4 utilizes a Sellita SW200 Swiss Automatic movement. This movement is self-winding, meaning it gains power from the natural motion of your wrist. When fully wound, it typically has a power reserve of approximately 38-42 hours.
3.2 Unidirectional Rotating Bezel
The watch features a unidirectional rotating bezel. This bezel can be used to measure elapsed time, particularly useful for diving or timing events. To use, align the triangle marker on the bezel with the minute hand at the start of the event. The minute hand will then indicate the elapsed time against the bezel's scale. The bezel rotates only counter-clockwise to prevent accidental increases in measured time, which is a safety feature for divers.
3.3 Water Resistance
This watch is water-resistant to 200 meters (20 ATM / 660 feet). This rating makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving. Ensure the crown is always fully screwed down before any contact with water.
- 200m (20 ATM): Suitable for swimming, snorkeling, and recreational diving.
- Important: Do not operate the crown or pushers (if present) while the watch is submerged or wet.
4. Care and Maintenance
- Cleaning: Wipe the watch case and crystal with a soft, dry cloth. For the leather strap, avoid excessive moisture and harsh chemicals.
- Leather Strap Care: Genuine leather straps are susceptible to wear and tear from sweat, water, and friction. Avoid prolonged exposure to direct sunlight, extreme temperatures, and moisture to preserve its condition. Clean with a damp cloth and mild soap if necessary, then allow to air dry completely.
- Avoid Shocks: While robust, avoid dropping the watch or subjecting it to severe impacts, which can affect the delicate internal movement.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices) as these can affect the accuracy of the mechanical movement.
- Service: For optimal performance, it is recommended to have your automatic watch serviced by an authorized Gevril service center every 3-5 years. This includes cleaning, lubrication, and adjustment of the movement.
- Storage: When not wearing the watch for an extended period, store it in a cool, dry place, preferably in its original box or a watch case.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently. | Insufficient power reserve. | Manually wind the watch (refer to Section 2) and wear it regularly. Consider a watch winder if not worn daily. |
| Watch runs too fast or too slow. | Exposure to strong magnetic fields or in need of regulation. | Demagnetize the watch (can be done by a watchmaker). If problem persists, seek professional service for regulation. |
| Date does not change at midnight. | AM/PM setting is incorrect. | Advance the time by 12 hours. The date should change around midnight. |
| Water inside the watch. | Crown not fully screwed down or seals compromised. | Immediately take the watch to an authorized service center. Do not attempt to dry it yourself. |
