Funzionamento dell'orologio

Cronometraggio

The watch displays hours, minutes, and seconds using analog hands. The quartz movement ensures accurate timekeeping with a precision of approximately ±20 seconds per month.

Funzione cronometro

The Casio MWA-300H-1AV includes a 1/10-second stopwatch for precise timing. This function is controlled by the two push-buttons located on either side of the crown.

• Starting the Stopwatch: Press the upper right button to start timing.
• Stopping the Stopwatch: Press the upper right button again to stop timing.
• Resetting the Stopwatch: While the stopwatch is stopped, press the lower right button to reset it to zero.
• Tempo parziale: Press the lower right button while the stopwatch is running to record a split time. Press it again to return to the current elapsed time.

The three sub-dials on the watch face indicate stopwatch minutes, seconds, and 1/10 seconds.

Resistenza all'acqua (100M)

This watch is rated for 100-meter (330 feet) water resistance. This means it is suitable for swimming, showering, and recreational water activities. It is not suitable for scuba diving or high-impact water sports.

• Assicurarsi che la corona sia completamente inserita prima di qualsiasi contatto con l'acqua.
• Non azionare la corona o i pulsanti mentre l'orologio è bagnato o immerso.
• Dopo l'esposizione all'acqua salata, sciacquare l'orologio con acqua dolce e asciugarlo.

Display luminoso

The hour and minute hands, along with certain markers, are treated with a luminous material that absorbs light and glows in the dark, providing readability in low-light conditions.

Manutenzione

Pulizia

• Pulire regolarmente la cassa e il cinturino dell'orologio con un panno morbido e asciutto per rimuovere sporco e umidità.
• For resin bands, a mild soap solution and a soft brush can be used, followed by thorough rinsing and drying.
• Evitare l'uso di detergenti chimici, solventi o materiali abrasivi, poiché potrebbero danneggiare la finitura dell'orologio.

Sostituzione della batteria

The watch is powered by one SR920SW battery, which has an approximate lifespan of 3 years. When the watch stops or the second hand moves erratically, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.

Precauzioni per la resistenza all'acqua

• Have the water resistance gaskets checked and replaced every 2-3 years, especially if the watch is frequently exposed to water.
• Avoid exposing the watch to extreme temperature changes, which can affect the water resistance seals.

Risoluzione dei problemi

• L'orologio non è in esecuzione: Controllare che la corona sia completamente inserita. In tal caso, potrebbe essere necessario sostituire la batteria.
• L'orario non è preciso: Ensure the crown is fully pushed in. If the time continues to be inaccurate, the watch may require servicing.
• Date does not change: Manually advance the date to ensure it is not stuck. If the issue persists, consult a service center.
• Fogging inside the crystal: This may indicate a loss of water resistance. Avoid further water exposure and have the watch inspected by a technician immediately.
