Wrist circumference: 17cm Working #3438 Thank you for viewing. We sell genuine brand-name items that are pre-owned. Please examine the photos carefully before purchasing. All included accessories are shown in the photos. The impression of the actual product may differ from the photos, but we take pictures using natural light to make them as close to the real item as possible. Sizes are also indicated in the photos using a ruler, so please check there. As these are pre-owned items at the time of purchase, we cannot answer questions regarding the period of use since the original purchase. We do not hold items, so there is no need to check for stock availability. Please be aware of the above before making a purchase.
