Tissot Carson Premium Watch - Silver - 30mm

No, the Tissot Carson Premium Watch has a water resistance of 5 bar (50 meters), which is suitable for splashes and brief immersion but not for swimming or diving.

If worn daily, the automatic movement should keep itself wound. If you wear it intermittently, it's recommended to wind it manually every 1-2 days to maintain the 38-hour power reserve and ensure accuracy.

An automatic watch is powered by a mechanical movement that uses the motion of the wearer's wrist to wind a mainspring. A quartz watch is powered by a battery and uses an electronic oscillator to regulate timekeeping.

While you can wear it while sleeping, it's generally recommended to take it off to avoid unnecessary wear and tear, and to allow your skin to breathe. If you don't wear it for more than 38 hours, you will need to re-wind and set it.

Use a soft, dry cloth for regular cleaning. For more persistent dirt, use a slightly damp cloth and dry immediately. Avoid using soaps or cleaning solutions, as they can damage the finish or get trapped in the links.

It means that after fully winding the watch, it will continue to run accurately for approximately 38 hours without any movement or manual winding.

Yes, sapphire crystal is exceptionally hard and highly resistant to scratches, though it can still be chipped or cracked under significant impact.

The watch may have run out of power. Manually wind the crown 30-40 times clockwise while pulled out to the first position. Ensure the crown is pushed in fully. If it stops again shortly after winding, the power reserve may be compromised, and a service might be needed.

Ensure you are not trying to change the date between 9 PM and 3 AM, as this can damage the movement. Adjust the time to be before 9 PM, set the date, and then advance the time past midnight to let the date change. Finally, set the correct time.

Minor discrepancies (a few seconds per day) are normal for automatic watches. However, significant time loss or gain could indicate the watch has been exposed to strong magnetic fields, received a shock, or requires servicing. Remove from magnetic sources and see if accuracy improves. If not, professional servicing is recommended.

Ensure you are turning the crown in the correct direction (counter-clockwise to unscrew, clockwise to screw down). If it still feels stiff, do not force it. There might be debris in the threads or an issue with the crown stem. Consult a watchmaker.
