Using your Seiko Presage watch is easy. Just wind it manually if the automatic movement hasn't charged it enough. You can wear it in water up to 10 bar, but avoid high - pressure water like diving into a pool. When it comes to maintenance, keep it clean with a soft cloth. If you're not wearing it for a long time, store it in a dry place. Check the timekeeping regularly, and if you notice any issues, take it to a professional watch repairer. Don't try to open the caseback yourself as it might damage the watch.
