Many people use watches on the left wrist, but is the use on the right wrist is not wrong. The wrist most often used to attach the clock is left. Because the majority of the population uses the right hand, and the crown (or clockwork player) is usually on the right, so it is easier to adjust it using the right hand so the watch is usually in the left hand. Is this your first experience in wearing mens watches? If you answer yes, you can read this article.
There are no rules on which hand to put on a watch, it only depends on how comfortable it is to set the clock. The popularity of smartwatches on brands and classic digital clocks is increasingly making more people use watches without a player lever than ever before. If you use an analog watch that needs to be adjusted to the player, there is no standard rule about which hand is right. You must ensure that you will be comfortable when you wear a watch.
