How can I determine the correct measurement for a ring or watch bracelet? How can I find my ring size? A finger size can be affected by many factors, such as the time of day, weather, weight, and nutrition. The best way to determine the correct ring size for a finger is to wear a ring continually, under varied conditions, for a period of time. If you don't know the ring size you need, we advise that you visit one of our Retail Stores to be measured. You may also use the ring-size measuring device tool at the time of your purchase. How can I purchase a watch with a metal bracelet already adjusted to my wrist size? At the time of purchase, please use the measuring device. We will send you the watch with the bracelet fitted to the size you specify.
