Setup
Before using your watch, please familiarize yourself with its components and initial setup procedures.
1. Setting Analog Time
- Gently pull out the crown (the knob on the right side of the watch case) to the first or second click position (depending on the model, usually the second click for time setting).

3. Strap Adjustment
Your watch comes with a durable strap. Adjust the buckle to ensure a comfortable and secure fit on your wrist. The strap should be snug but not too tight, allowing for proper circulation.

5. Water Resistance
Your Diesel Mega Chief watch is water-resistant up to 10 BAR (100 meters). This rating means it is suitable for showering, swimming, and snorkeling. It is not recommended for high-impact water sports or scuba diving. Always ensure the crown is fully pushed in before exposing the watch to water.

Maintenance
Proper care will help preserve the appearance and functionality of your Diesel watch.
1. Cleaning
- Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt.
- For more thorough cleaning, use a slightly damp cloth with mild soap, then wipe dry immediately. Avoid harsh chemicals or abrasive materials.
2. Battery Replacement
Your watch is powered by a long-lasting battery. When the watch stops or the digital display fades, it indicates the battery needs replacement. It is highly recommended to have the battery replaced by an authorized Diesel service center or a professional watchmaker to ensure proper sealing and maintain water resistance.
3. Water Resistance Care
- Avoid exposing the watch to extreme temperature changes (e.g., hot showers, saunas) as this can affect the seals.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
- Do not operate the crown or pushers when the watch is wet or submerged.
4. Storage
When not in use, store your watch in a cool, dry place, away from direct sunlight and extreme temperatures. The original watch box is ideal for storage.
