Rolex watches are expensive to replace and repair, so protect your watch by winding it on a stationary surface where it can't slip out of your hand. The crown is located on the side of your watch by the 3 o'clock marking. Turn the crown counterclockwise until you feel it release from the last thread. It will pop out slightly from the side of the watch. With your thumb and index finger, slowly turn the crown clockwise 360 degrees, or a full rotation, at least 30 to 40 times. This fully winds the watch. If you only rotate the crown clockwise a few times then the watch will not be fully wound. Rolex designs its watches so it is impossible to over wind them. A device built into the watch will prevent you from over winding the Rolex. Return the crown to its normal position by gently pushing the crown towards the watch and screwing it back on to the threads by turning it clockwise. Your Rolex watch is now wound. If you've wound your watch and it doesn't immediately start working, leave it alone for a little while or rotate it back and forth on your wrist. It may take a little motion for the watch to be working properly. A Rolex watch that stays motionless for approximately 24 hours will usually not wind itself and will need to be manually wound. Keep your Rolex on if you don't want to repeatedly wind it. If your Rolex still doesn't work after winding it, you may have a more serious problem. Take your watch to a local certified and authorized dealer who can assess the watch. If it is broken, the dealer will ship your Rolex to a factory in Switzerland for repairs.

Summary: Place your watch on a soft, flat surface. Unscrew the crown. Wind your Rolex. Screw the crown onto the Rolex. Be patient. Move around. Send your watch for repairs if it still does not work.

It is natural to feel defensive when you are being criticized, but allowing yourself to get upset and show your emotions will not help the situation. Keep in mind that we all make mistakes when we are learning a new skill, so criticism is inevitable and if you deal with it in a constructive way you may learn something valuable as a result. So try to stay calm even if the person who is criticizing you seems agitated. Do not match their emotions because it may make you seem incapable of handling criticism and it will interfere with your ability to learn something from the criticism. Take deep breaths. When you are being criticized, focusing on your breathing can help to keep you calm. Try counting to five (in your head) as you breathe in, then hold your breath to the count of five, and then exhale slowly. Try to smile. Even a small smile can help you to feel better and it may cause the person who is criticizing you to relax a bit too. Before responding and even before thinking about the criticism that you received, give yourself time to cool down. Do something you enjoy for about 20 minutes such as listening to your favorite type of music, reading a book, or taking a walk. Giving yourself some time to cool down after receiving harsh criticism will help you to deal with it in a constructive way, rather than just reacting based on your emotional response. When accepting criticism in a way that's healthy for you, you need to remember to compartmentalize. Try not to think about criticism as being personal or speaking against other things that you do. Take it as it is and do not add things to it or make assumptions about other aspects of yourself based on what was said. For example, if someone gives you criticism about a painting you did, it does not mean that you're a bad artist. You can have a few flaws in a piece or a painting that no one likes, and you can still be a great artist. Sometimes criticism is not meant to help, it is meant to hurt. Before you decide what to do about the criticism you received, take some time to think about it. Ask yourself some questions to try to understand why the criticism was made. Were the comments about something you can control? If not, why do you think they are being made? Does the critical person's opinion of you really matter? Why or why not? Are you in competition with this person? If so, could the criticism be a reflection of that? Do you feel like you are being bullied? If so, have you sought help for the problem? (If you feel like you are being bullied at school or at work, talk to someone who can help such as a teacher or human resources representative.) Whether the criticism you received was based on your performance or just plain mean, it is important to discuss what happened and how it made you feel. Wait until you can get away from the person and find someone who you trust to confide in. Tell them about what happened and how it made you feel. Discussing the criticism with a trusted friend or family member may also help you to better understand the criticism and why it was given. Once you have taken steps to calm yourself and understand the criticism, you will need to work on redirecting your focus onto the positive aspects of yourself. If you focus too much on things you need to improve, you may start to feel depressed and helpless. Instead, try making a list of as many strengths as you can think of to start rebuilding your self-esteem. For example, you might include in your list things like "good cook," "funny," or "avid reader." List as many things as you can think of and read over your strengths to remind yourself of what you do well.

Summary: Stay calm. Give yourself time to cool off. Separate the criticism from other areas of yourself. Consider the motivation for the criticism. Talk to someone about what happened. Redirect your focus.
