Using your Seiko watch is easy. Just set the time and date according to your needs. When you're out and about, it can handle splashes and brief immersions in water thanks to its 100M water resistance, but don't wear it for diving or in hot tubs. To keep it looking good, wipe it with a soft cloth regularly. Avoid knocking it against hard objects as the sapphire crystal, while scratch - resistant, can still be damaged. If you need to change the battery, take it to a professional watch repairer to ensure proper installation.
