1) Wearing a Wrist Watch Properly Don’t wear a watch with a face that is too big. Watch faces are measured in millimeters. Men’s watches average between 34mm-50mm, although they can be larger. You should never wear a watch bigger than 50mm, at most, but 34mm-40mm is standard and ideal for both men and women.
2) Choosing the Right Wrist Watch for the Occasion Match your watch to your shoes. As a general rule, you are wearing dress shoes, a dress watch would be appropriate. If you are wearing sneakers, then a sports watch would be appropriate. If you are somewhere in between, such as boots, boat shoes, or flip-flops, an everyday casual watch is your best bet.
3) Make Sure you Clean your Watch There are two parts of a watch you need to keep clean: the face, and the band
The Watch Face To clean the watch face, fill a dish with warm water and a bit of mild detergent, like Dial dish soap. Dip a chamois cloth or soft-bristled toothbrush into the soapy water, and gently brush over the top of the watch face. You shouldn’t press down or scrub vigorously – you merely want to loosen and remove the daily dirt and dust that can collect on the face of your watch.
The Watch Band The method of cleaning your watch band depends on its material. Leather, stainless steel, nylon, and rubber are all common types of watch bands. If possible, remove the watch bands before cleaning them so you can wipe them down thoroughly without damaging the watch face.
