3. Istruzioni per l'uso
3.1 Cronometraggio di base
Once the time and date are set, the watch will operate continuously, displaying the current time and date. The quartz movement ensures accurate timekeeping.
3.2 Utilizzo del cronografo
La funzione cronografo consente una misurazione precisa del tempo trascorso.
- Avvio/Arresto: Press button (A) to start the chronograph. Press button (A) again to stop it.
- Reset: While the chronograph is stopped, press button (C) to reset all chronograph hands to the zero position.
3.3 Caratteristica luminosa
The hands and markers of your watch are treated with a luminous material. For optimal glow in the dark, expose the watch face to a bright light source (natural or artificial) for a few minutes. The intensity and duration of the glow will depend on the exposure time and light intensity.
3.4 Water Resistance (3ATM/30M)
Your NAVIFORCE NF7105 watch is water resistant to 3ATM (30 meters or 100 feet). This means it is suitable for daily use, such as splashes, rain, and hand washing. However, it is non suitable for swimming, diving, showering, or bathing. Do not operate the crown or pushers when the watch is wet or submerged in water. Avoid exposure to hot water or steam, as this can compromise the water seals.

4. Manutenzione
4.1 Pulizia
Regularly wipe your watch with a soft, dry cloth to remove dust and dirt. For the silicone strap, you can use a slightly damp panno con sapone neutro, quindi risciacquare e asciugare accuratamente. Evitare l'uso di prodotti chimici aggressivi o materiali abrasivi.
4.2 Sostituzione della batteria
The watch is powered by a battery. 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 functionality.
4.3 Conservazione
When not wearing your watch for an extended period, store it in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields.
4.4 Precauzioni generali
- Avoid exposing the watch to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F).
- Tenere l'orologio lontano da forti campi magnetici, che possono compromettere la precisione del movimento al quarzo.
- Avoid direct contact with solvents, detergents, perfumes, and cosmetics, as they can damage the case, strap, or seals.
- Do not attempt to open the watch case yourself, as this will void the warranty and may cause damage.
5. Risoluzione Dei Problemi
- Orologio non in funzione: Controlla che la corona sia completamente inserita. In tal caso, potrebbe essere necessario sostituire la batteria.
- L'ora o la data non sono corrette: Refer to Section 2.1 and 2.2 to re-adjust the time and date.
- Le lancette del cronografo non si azzerano: Follow the Chronograph Hand Position Adjustment steps in Section 2.3.
- Condensa all'interno dell'orologio: This may indicate a breach in the water resistance. Stop using the watch immediately and have it inspected by a professional watch repair service.
