Impostare
1. Avvolgimento iniziale
Your Timex M79 watch features an automatic movement. Before wearing for the first time or after a period of inactivity, manually wind the watch by rotating the crown clockwise approximately 20-30 times. This builds up the initial power reserve. The watch will then continue to wind itself through the motion of your wrist while worn.
2. Impostazione di ora e data
- Pull the crown out to the first position to set the date and day. Rotate the crown to adjust.
- Pull the crown out to the second position to set the time. Rotate the crown to move the hands. Push the crown back in to start the watch.
- Importante: Avoid setting the date or day between 9 PM and 3 AM, as this can damage the movement. If you need to set the date during these hours, first set the time outside this range (e.g., to 6 AM), then adjust the date, and finally set the correct time.
3. Regolazione del braccialetto
The stainless steel bracelet features a sliding clasp for adjustment. To resize:
- Locate the small lever on the clasp.
- Use a small tool (like a screwdriver or spring bar tool) to lift the lever, which will unlock the clasp from its position on the bracelet.
- Slide the clasp along the bracelet to the desired length.
- Press the lever back down firmly to secure the clasp in place. Ensure it snaps securely between the links to prevent accidental opening.

Istruzioni per l'uso
Movimento automatico
Your M79 watch is powered by an automatic mechanical movement. This means it does not require a battery. The movement is powered by the natural motion of your wrist. When fully wound, it has a power reserve of approximately 40 hours. If the watch stops, simply wear it for a few hours or manually wind it as described in the "Initial Winding" section.
Lunetta girevole unidirezionale
The watch features a red and black unidirectional rotating bezel. This bezel is designed to rotate only in one direction (counter-clockwise) to prevent accidental changes that would indicate a longer elapsed time. It can be used to measure elapsed time, such as dive times or other timed events. Align the bezel's zero marker with the minute hand at the start of an event, then read the elapsed time from the bezel as the minute hand progresses.
Resistenza all'acqua
The Timex M79 is water resistant to 50 meters (165 feet). This rating means the watch is suitable for short periods of recreational swimming. It is non recommended for diving, snorkeling, or high-impact water sports. Always ensure the crown is fully pushed in before any contact with water. Avoid operating the crown while the watch is wet or submerged.
