Setup
Setting the Time
- Pull out the crown: Gently pull the crown (the small knob on the side of the watch case) out to the first click position.
- Adjust the time: Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Push in the crown: Once the time is set, push the crown back into its normal position.
Setting the Date
This watch features a date display. To set the date:
- Pull out the crown: Gently pull the crown out to the first click position.
- Adjust the date: Turn the crown counter-clockwise to advance the date. Avoid setting the date between 9 PM and 3 AM, as this may interfere with the automatic date change mechanism. If the current time falls within this period, first set the time outside this range, then set the date, and finally reset the time.
- Push in the crown: Once the date is set, push the crown back into its normal position.

Operation
Timekeeping
Your Calvin Klein Time K4N211C1 watch is powered by a precise quartz movement, ensuring accurate timekeeping. Once the time and date are set, the watch will operate continuously until the battery requires replacement.
Water Resistance
This watch is water-resistant up to 30 meters (3 ATM). This means it is suitable for everyday use and can withstand splashes or brief immersion in water. It is not suitable for swimming, showering, or diving. Avoid operating the crown while the watch is wet to prevent water ingress.
Maintenance
Cleaning
- Case and Crystal: Wipe the watch case and crystal with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
- Leather Strap: Avoid prolonged exposure of the leather strap to water, direct sunlight, or harsh chemicals. Clean with a soft, dry cloth. If the strap becomes wet, allow it to air dry naturally, away from direct heat.
Battery Replacement
The watch is powered by one lithium metal battery. When the watch stops or the second hand begins to jump erratically (if applicable), it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
Storage
When not in use, store your watch in a cool, dry place, away from direct sunlight and strong magnetic fields.
