Configuració
Enrotllament inicial
Your Seiko SNXA03 watch is powered by an automatic movement, which means it winds itself through the motion of your arm. If the watch has stopped, gently swing it from side to side for about 30 seconds to initiate the movement. Wearing the watch for several hours will build up the power reserve.
Configuració de l'hora i la data
- Traieu la corona: Locate the crown on the right side of the watch case. Gently pull it out to the second click position (farthest out). The second hand will stop.
- Estableix l'hora: Rotate the crown to move the hands clockwise until the desired time is displayed. To avoid confusion between AM and PM for the date change, advance the hands past 12 o'clock. If the date changes, you are in the AM hours.
- Estableix la data i el dia: Push the crown in one click to the first click position. Rotate the crown clockwise to set the date and counter-clockwise to set the day of the week. Avoid setting the date or day between 9:00 PM and 4:00 AM, as this can damage the movement.
- Empenyeu la corona: Once the time, date, and day are set, push the crown back fully into the normal position. The second hand will resume movement.
Note: For optimal accuracy, ensure the crown is always fully pushed in when not setting the watch.
Ajust de polsera
The stainless steel bracelet of your watch can be adjusted for a comfortable fit. It is recommended to have this adjustment performed by a qualified jeweler or watch technician to prevent damage to the bracelet or watch case.
Instruccions de funcionament
Moviment automàtic
The Seiko SNXA03 is equipped with an automatic mechanical movement. This means it does not require a battery. The watch is powered by the natural motion of your wrist, which causes an oscillating weight inside the watch to rotate and wind the mainspring. When fully wound, the watch has a power reserve that allows it to continue running for a certain period even when not being worn.
Water Resistance (100 Meters / 330 Feet)
Your watch is water resistant to 100 meters (330 feet). This rating makes it suitable for everyday use, including showering, swimming, and snorkeling. It is no suitable for scuba diving 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.
Manteniment
Neteja
Per mantenir l'aspecte del rellotge, netegeu la caixa i el braçalet regularment amb un drap suau i sec. Per a l'acer inoxidable, una mica de...amp cloth can be used, followed by a dry cloth. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish or seals.
Emmagatzematge
Quan no porteu el rellotge durant períodes prolongats, guardeu-lo en un lloc fresc i sec, allunyat de la llum solar directa, temperatures extremes i camps magnètics forts. Una caixa o una bossa per al rellotge és ideal per a la protecció.
Manteniment periòdic
Like any precision mechanical instrument, your Seiko automatic watch benefits from periodic servicing to ensure its accuracy and water resistance. It is generally recommended to have your watch inspected and serviced by an authorized Seiko service center every 3 to 5 years.
Cristall Hardlex
The watch features a Hardlex crystal, which is Seiko's proprietary hardened mineral glass. It offers good scratch resistance for daily wear, but it is not entirely scratch-proof. Avoid impacts and contact with abrasive surfaces to preserve its clarity.
Resolució de problemes
- Watch has stopped or is running slowly:
This is common for automatic watches if they haven't been worn or moved for a while. Gently swing the watch from side to side for about 30 seconds to initiate winding. Wear the watch for several hours to build up the power reserve. If the issue persists after sufficient winding, contact a service center.
- Time or Date is incorrect:
Refer to the "Setting the Time and Date" section under Setup. Ensure the crown is fully pulled out to the correct position for setting and then pushed back in completely.
- Condensació dins del cristall:
If you notice moisture or condensation under the crystal, this indicates a potential breach in the watch's water resistance. Immediately take the watch to an authorized service center to prevent further damage to the movement.
