Using your Tissot PRX Powermatic 80 watch is easy. Just wear it on your wrist, and the automatic movement will wind itself as you move your arm. When you're not wearing it for a while, remember that it has up to 80 hours of power reserve, so you don't have to worry about it stopping too quickly. For cleaning, use a soft, dry cloth to wipe the watch regularly to keep it looking shiny. Avoid exposing the watch to extreme temperatures, water for extended periods (even though it's durable, it's best not to take risks), and strong magnetic fields. If you want to change the bracelet, use the quick - release feature for a hassle - free swap. Enjoy your stylish and functional timepiece!
