Using this Tissot PRX 25mm quartz watch is a breeze. Just set the time and date according to your local time zone when you first get it. Since it's battery - powered, you don't have to worry about winding it regularly. When it comes to water resistance, it can handle splashes, short swims, and even light rain as it's water - resistant up to 10 bar. But avoid long - term immersion or high - pressure water activities. To keep your watch in top shape, clean it regularly with a soft, dry cloth. This will help maintain the shine of the rose gold PVD coating and keep the sapphire crystal looking clear. If you notice the watch is losing time or the battery indicator shows it's low, take it to a professional watchmaker for battery replacement. This way, your watch will stay both stylish and accurate for a long time.
