2.3 Setting the Date

3. Operating the Chronograph Functions
Your Nautica N22503 watch features a chronograph function for measuring elapsed time. The chronograph is operated using the pushers located on either side of the crown.

3.3 Water Resistance
This watch is water resistant to 660 feet (200 meters), making it suitable for recreational scuba diving. Ensure the crown is fully pushed in before any contact with water. Do not operate the crown or pushers while the watch is wet or submerged, as this can compromise the water resistance.
4. Maintenance
4.1 Cleaning
To maintain the appearance of your watch, wipe the case and crystal with a soft, dry cloth regularly. For the leather strap, avoid excessive moisture and harsh chemicals.
4.2 Battery Replacement
The watch is powered by a precise Swiss-Quartz movement. When the battery needs replacement, it is recommended to take your watch to an authorized service center or a qualified watchmaker to ensure proper sealing and water resistance integrity.
4.3 Leather Strap Care
The leather strap is susceptible to wear and tear from moisture, sweat, and direct sunlight. To prolong its life, avoid prolonged exposure to water and extreme temperatures. Clean with a damp cloth and allow to air dry.
