Setup: Setting the Time
To ensure accurate timekeeping, follow these steps to set your watch:
- Vytáhněte korunu: Gently pull the crown (the knob on the side of the watch) out to its farthest position. This is typically the second click when pulling the crown.
- Nastavte čas: Rotate the crown either clockwise or counter-clockwise until the hour and minute hands indicate the correct time.
- Zatlačte korunku zpět: Once the time is set, push the crown firmly back into its original, closed position. This ensures water resistance and starts the watch movement.

Operating the Mechanical Movement
Your Marathon GPM watch features a dual-winding mechanical movement (ETA 2801) that can be powered in two ways:
- Ruční navíjení: To manually wind the watch, rotate the crown clockwise while it is in the closed position. This is recommended if the watch has stopped or has not been worn for an extended period. A fully wound watch will run for approximately 41 hours.
- Automatické samonavíjení: The watch also features an automatic self-winding rotor. Normal wrist movement throughout the day will cause the rotor to oscillate, transferring energy to the mainspring and keeping the watch wound. You may notice a slight mechanical noise or feel the rotor oscillating, which is normal and indicates the automatic winding system is functioning.
For optimal performance, wear the watch regularly or manually wind it if it has been inactive.

Údržba a péče
Proper care will extend the life and maintain the performance of your Marathon GPM watch:
- Čištění: Pouzdro hodinek a sklíčko otřete měkkým hadříkemamp tkanina. Vyhněte se používání agresivních chemikálií nebo abrazivních materiálů.
- Voděodolnost: The watch has improved water resistance. Ensure the crown is fully pushed in before exposing the watch to water. Avoid operating the crown while the watch is wet or submerged.
- Extrémní teploty: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect the movement's accuracy and seals.
- Magnetická pole: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices), which can magnetize the movement and affect accuracy.
- Krystal: The watch features a scratch-resistant sapphire crystal. While highly durable, it is not entirely impervious to damage. Avoid direct impacts.
- Tritium Illumination: The tritium gas tubes provide constant illumination without external charging. Their brightness will gradually diminish over many years. This is a natural process and not a defect.
- Servis: Mechanical watches benefit from periodic servicing by a qualified watchmaker, typically every 3-5 years, to ensure optimal performance and longevity.

Odstraňování problémů
If you encounter issues with your watch, consider the following:
- Hodinky neběží:
- Ensure the watch is sufficiently wound. Manually wind the watch by rotating the crown clockwise for 30-40 turns.
- If the watch has been inactive, it may take a few seconds of movement or manual winding for the second hand to start moving.
- Nepřesné měření času:
- Check if the watch is fully wound. An under-wound mechanical watch can lose accuracy.
- Avoid strong magnetic fields, which can affect the movement. If suspected, a watchmaker can demagnetize the watch.
- Extreme temperature fluctuations can temporarily affect accuracy.
- Kondenzace pod krystalem:
- If condensation appears, it may indicate a breach in water resistance. Have the watch inspected by a qualified watchmaker immediately to prevent internal damage.
For issues not resolved by these steps, contact Marathon customer support or a certified watch repair center.
