Operating instructions for:

Collections: 101, Islandus, Frisland, Sif NART, MMXVIII.

1. Date Adjustment Timing: Avoid making calendar adjustments between 20:00 and 02:00. During this period, the automatic date change process is in motion, and tampering could potentially harm the mechanism.

2. Setting the Date: Gently pull the crown out one click (position II) and then rotate it in reverse. For the Sif NART model, begin by unscrewing the crown until it releases.

3. Adjusting the Time: Pull the crown out two clicks (position III) and then turn it forward or backward to set the time.

4. Secure Crown Position: After adjusting the time or date, ensure the crown is fully pushed in (position I) to seal the watch against water and humidity. Specifically for the Sif NART model, remember to screw the crown back onto the case securely.

Operating instructions for:

Collections: Vínland Chronograph Classic and Vínland Chronograph Tachymeter.

1. Setting the Time: Pull out the crown to one click (position II) and turn it to adjust the time. After setting, push the crown fully back in (position I) to protect the watch from water and humidity.

2. Starting the Timer: Press the start/stop button (A) once. A second press will halt the timer.

3. Stopping the Timer: If you want to end the timing session, simply press button (A) again.

4. Resetting the Chronograph: View the elapsed time, then press the second button (B) to reset. Always reset after use; otherwise, the chronograph will resume from the last stop time when next activated.

Note: A chronograph function measures elapsed time while simultaneously showing the current time.

Operating instructions for:

Collections: Vínland GMT

1. Calendar Adjustment Caution: Avoid adjusting the calendar between 20:00 and 02:00. The watch's automatic date change mechanism is activated during these hours, and adjusting it might damage the mechanism.

2. Setting Date & GMT Hand: Pull the crown out to one click (position II). Turn the crown forward to adjust the GMT hand. Turn the crown backward to adjust the date.

3. Setting the Time: Pull the crown out to two clicks (position III). Turn the crown either forward or backward to set the desired time.

4. Sealing the Watch: After setting the time or date, ensure the crown is pushed fully in (position I) to protect your watch from water or humidity.

Automatic mechanical movements

A self-winding watch movement incorporates a mechanism that harnesses the natural movements of the wearer's body to wind the mainspring. For optimal functioning, a self-winding or automatic watch requires the mainspring to accumulate a substantial power reserve. Thus, wearing the watch for at least eight hours daily is recommended to maximize this power reserve.

In addition to being wound through the wearer's motions, automatic wristwatches can also be manually wound by turning the crown. This feature allows the watch to remain operational even when not worn, or in situations where the wearer's arm movements may not be sufficient to keep it self-wound.

Should the watch stop due to the depletion of its power reserve, it can be manually rewound by hand. Simply turn the crown about 10 times clockwise to reinitiate its operation.

General information

JS Watch Co. Reykjavik rigorously tests your mechanical timepiece both during and after assembly. With proper care and adherence to manufacturer recommendations, your timepiece is designed for a prolonged life. We highly recommend bringing in your timepiece for servicing and testing every four to five years. This comprehensive service entails an oil change, thorough cleaning, precise tuning, and meticulous water seal testing.

By entrusting your timepiece to regular servicing, you ensure its enduring visual appeal and its accurate timekeeping performance for many years ahead.

POWER RESERVE

Wearing your watch automatically winds the movement, and when it's fully wound, you can enjoy approximately 42 hours of power reserve for most JS collections, and 63 - 65 hours of power reserve for the Vínland Chronograph and GMT collections.

SECOND TIME ZONE (GMT COMPLICATION FEATURE)

Timepieces equipped with this feature include a subdial. To adjust the GMT hand, simply pull the crown out one click (to position II) and then turn it forward. This action will set the GMT hand according to your desired time zone. In models with a 24-hour display, this functions as a display for the second time zone.

WATER RESISTANCE AND CARE TIPS FOR YOUR WATCH

It's important to safeguard your watch from water and moisture. While no watch can be considered fully waterproof, watches with a screw-on crown offer enhanced water resistance. A screw-on crown needs to be properly tightened onto the case to maintain the watch's waterproof integrity.

The water resistance rating of 5 ATM signifies that the watch can endure pressure equivalent to the pressure experienced at a depth of 50 meters. This rating indicates that the watch has been tested and subjected to a leak test at this depth. However, this measurement is specifically tied to static pressure and doesn't consider dynamic activities like swimming, diving, or water jets. These activities can impose significantly higher pressure loads that might harm the watch mechanism.

A water resistance rating of 5 ATM means that the watch is suitable for everyday activities such as showering and handwashing. However, it's important to recognize that this model isn't intended for swimming or diving. It's also crucial to remember that environmental factors can impact the watch's gaskets over time, causing them to lose their effectiveness and decreasing water resistance. Everyday wear, minor impacts against the crown, and other activities can also gradually affect water resistance. To maintain the best performance, ensure your watch is regularly serviced by an authorized technician.

Depending on factors like climate, usage, and maintenance practices, we recommend a comprehensive watch service every five to seven years. To maintain the integrity of your watch, never operate the buttons or adjust the crown in damp or wet conditions. In the unfortunate event that water, moisture, or condensation enters the dial unintentionally, we advise you to have your watch examined promptly.

Thank you for taking care of your timepiece and ensuring its longevity.
