Introduction
This manual provides detailed instructions for the setup, operation, maintenance, and troubleshooting of your Kenneth Cole New York KC1640 Digital Watch. Please read this manual thoroughly to ensure proper use and care of your timepiece.
The KC1640 features a reliable Japanese digital-quartz movement, a durable polyurethane strap, and a solid stainless steel case. It displays time, date, day, and year, and is water-resistant up to 30 meters (99 feet).
Setup
1. Initial Power On
Your watch is typically pre-installed with a battery. If the display is blank, gently press any button to activate it. If it remains blank, the battery may need replacement (refer to the Maintenance section).
2. Setting Time, Date, Day, and Year
- Press the MODE button repeatedly until you reach the time setting mode. The seconds display will likely flash.
- Press the SET/RST button to select the value you wish to adjust (e.g., hours, minutes, month, day, year). The selected value will flash.
- Use the START/STOP button to increase the flashing value. Hold it down to advance rapidly.
- Repeat steps 2 and 3 for all desired settings (hours, minutes, AM/PM, month, day, year).
- Once all settings are correct, press the MODE button to exit the setting mode and return to the normal time display.
3. Strap Adjustment
The polyurethane strap is designed for comfort and durability. Adjust the buckle to find a comfortable fit on your wrist. Ensure it is snug but not too tight to allow for proper circulation.

Operating Instructions
1. Time Display
In normal mode, the watch displays the current time (hours, minutes, seconds) and typically the day of the week.
2. Using the MODE Button
Press the MODE button to cycle through different functions such as:
- Time Display (main screen)
- Date Display (month, day, year)
- Stopwatch/Chronograph
- Alarm Setting
- Timer (if available)
3. Using the LIGHT Button
Press the LIGHT button to illuminate the digital display for better visibility in low-light conditions. The backlight will typically stay on for a few seconds.
4. Using the START/STOP Button
This button is primarily used for starting and stopping functions like the stopwatch or timer, and for adjusting values during setting modes.
5. Using the SET/RST Button
This button is used to reset functions (e.g., stopwatch) or to select specific values for adjustment during setting modes.
6. Water Resistance
Your KC1640 watch is water-resistant up to 30 meters (99 feet). This means it is suitable for everyday use and can withstand splashes of water or brief immersion. It is not recommended for showering, swimming, or diving. Avoid pressing buttons while the watch is wet or submerged to prevent water ingress.
Maintenance
1. Cleaning Your Watch
Wipe the watch case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners, as they may damage the watch's finish or strap material.
2. Battery Replacement
The watch uses a standard watch battery. When the display becomes dim or stops functioning, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure the water resistance seal is properly maintained.
3. Storage
When not in use, store your watch in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields.
4. Strap Care
The polyurethane strap is durable but can degrade over time with exposure to chemicals, excessive sweat, or prolonged sunlight. Clean the strap regularly and avoid contact with harsh substances.

Troubleshooting
- Display is blank or dim: The battery may be depleted. Replace the battery.
- Incorrect time/date: Re-set the time and date following the instructions in the Setup section. Ensure AM/PM is correctly set.
- Buttons are unresponsive: Check if the watch is in a specific mode (e.g., setting mode) that restricts button functionality. If the issue persists, a battery replacement or professional inspection may be required.
- Difficulty reading display in sunlight: Some digital displays can be challenging to read in direct sunlight. Try to shade the watch face or adjust the viewing angle.
- Display issues in cold temperatures: Extreme cold can affect LCD performance. Allow the watch to return to a normal operating temperature.
- Water inside the watch: If you notice condensation or water inside the watch, stop using it immediately and take it to a qualified watch repair center. This indicates a compromised water resistance seal.
