Using your Tissot Gentleman Powermatic 80 Watch is easy. Just wear it on your wrist, and the automatic movement will wind itself as you move. You can also wind it manually if you haven't worn it for a while to get it started. For the best performance, keep it away from strong magnetic fields as they can affect the movement. When it comes to maintenance, take it to a professional watchmaker for servicing every 3 - 5 years. Clean the watch regularly with a soft, dry cloth to keep it looking its best. Avoid exposing it to water beyond its specified water - resistance level to prevent damage to the internal components.
