Using your Michele Deco Madison Mini watch is simple. Just set the time by pulling out the crown and turning it gently. To change the strap, use a small tool to remove the pins at the ends of the bracelet and then attach your new 12mm MICHELE strap. When wearing your watch, avoid exposing it to harsh chemicals like perfume or cleaning agents, as they can damage the finish. Also, try not to swim or shower with it, even though it has 5 ATM water resistance. For maintenance, wipe the watch regularly with a soft, dry cloth to keep it looking shiny. Take it to a professional watchmaker for servicing every few years to ensure it keeps accurate time.
