3. Setup

3.1 Adjusting the Bracelet

The woven stainless steel bracelet is adjustable to ensure a comfortable fit. To adjust the length:

1. Locate the clasp on the bracelet. It has a small lever that can be lifted.
2. Using a small flathead screwdriver or a similar sturdy tool, gently pry up the lever on the clasp. Avoid using sharp objects that could scratch the bracelet.
3. Once the lever is lifted, slide the clasp along the bracelet to your desired length. Ensure the clasp is positioned securely between the links.
4. Press the lever back down firmly until it snaps into place, securing the clasp.

3.2 Setting Time and Date

Your M79 watch features a 21-jewel automatic movement. It is powered by the motion of your wrist. If the watch has stopped or is running low on power, you can manually wind it or wear it for several hours to build up the power reserve.

1. To Wind Manually: Rotate the crown clockwise several times (approximately 20-30 rotations) to initiate power.
2. To Set the Date: Pull the crown out to the first click position. Rotate the crown clockwise or counter-clockwise to adjust the date.
3. To Set the Day: In the first click position, rotate the crown in the opposite direction to adjust the day. Note that the day may be displayed in multiple languages (e.g., English and Spanish) and will cycle through them.
4. To Set the Time: Pull the crown out to the second click position. The second hand will stop. Rotate the crown to move the hour and minute hands to the correct time. Push the crown back in to start the watch.

Note: The day and date typically change between 11:00 PM and 3:00 AM. Avoid setting the date or day during this period to prevent damage to the movement. If setting during this time, first advance the time past 3:00 AM, then set the date/day, and finally set the correct time.

4. Operating Instructions

4.1 Automatic Movement

The Timex M79 utilizes a 21-jewel automatic movement, which means it is self-winding. The movement of your wrist powers the watch. When fully wound, it has a power reserve of approximately 40 hours. If the watch is not worn for an extended period, it will stop. Simply pick it up, gently shake it, or manually wind it to restart.

4.2 Water Resistance

This watch is water resistant to 50 meters (165 feet). This rating makes it suitable for short periods of recreational swimming, showering, or washing hands. It is not suitable for diving, snorkeling, or prolonged water activities. Always ensure the crown is fully pushed in before any contact with water.

4.3 Unidirectional Rotating Bezel

The M79 features a unidirectional rotating bezel, meaning it only turns in one direction (counter-clockwise). This feature is useful for timing events, such as elapsed time during recreational swimming. To use:

1. Rotate the bezel so the triangle marker aligns with the minute hand.
2. As time passes, the minute hand will indicate the elapsed time against the bezel's markings.

5. Maintenance

5.1 Cleaning

Regular cleaning helps maintain your watch's appearance and longevity. Use a soft, damp cloth to wipe the case and bracelet. For the stainless steel bracelet, a soft brush with mild soap and water can be used, ensuring to rinse thoroughly and dry completely. Avoid harsh chemicals or abrasive materials.

5.2 Acrylic Crystal Care

The watch features an acrylic domed crystal, which provides a vintage aesthetic but can be more prone to scratches than sapphire crystals. Minor scratches can often be buffed out using a specialized acrylic polish. For deeper scratches, professional assistance may be required.

5.3 Servicing

Automatic movements benefit from periodic servicing, typically every 3-5 years, to ensure optimal performance and accuracy. This involves cleaning, lubricating, and adjusting the movement. Contact an authorized Timex service center for professional servicing.

6. Troubleshooting

• Watch Not Running: If the watch has stopped, it may need to be manually wound (see Section 3.2) or worn for a period to build up its power reserve. Ensure the crown is fully pushed in.
• Incorrect Time/Date: Refer to Section 3.2 for instructions on how to correctly set the time, day, and date.
• Water Intrusion: If you notice moisture inside the watch, immediately take it to an authorized service center. Do not attempt to open the watch yourself.
• Bracelet Discomfort: Ensure the bracelet is adjusted correctly to your wrist size (see Section 3.1). A bracelet that is too tight or too loose can cause discomfort.
