Using your Tissot Seastar 1000 watch is a breeze. Just wear it on your wrist and it'll start ticking with the automatic movement as you move. To set the time, gently pull out the crown and turn it to adjust. Make sure to push it back in firmly. When it comes to water resistance, it can handle up to 300 meters, but avoid pressing the crown underwater. For maintenance, keep it clean by wiping it with a soft cloth regularly. Avoid exposing it to extreme temperatures or magnetic fields. If you're not wearing it for a while, you can use a watch winder to keep the power reserve up. That way, your watch will keep looking great and running smoothly for years to come.
