When wearing it, avoid exposing it to extreme temperatures or strong magnetic fields as this may affect its performance. For maintenance, clean the leather band regularly with a soft, dry cloth to keep it looking good. If it gets wet, dry it immediately. As for the case, wipe it down with a microfiber cloth to remove dust and fingerprints. Check the water resistance periodically and have it serviced by a professional every few years to ensure it continues to work well.
