Using this Seiko watch is a breeze. Just set the time and date according to the instructions in the manual. When you're out and about, the big date calendar makes it easy to check the date at a glance. And the LumiBrite hands and markers are great for seeing the time in low - light conditions. For water resistance, it can handle swimming and snorkeling up to 100 meters, but avoid deep - sea diving. When it comes to maintenance, keep it clean by wiping it with a soft cloth regularly. If it gets wet, dry it thoroughly. Don't expose it to extreme temperatures or strong magnetic fields, as this can affect its performance. If you notice any issues with the timekeeping or the clasp, it's best to take it to a professional watch repair service.
