I am selling this item because it was given to me as a gift, but I never used it and it has been sitting at home. This is the SBXC021, a standard SBXC model. It is brand new and unused, and has been stored out of direct sunlight, so it is in excellent condition. Please check the photos for details. It also comes with a warranty. This is an expensive item, so please feel free to ask any questions or consult with me if you have any concerns. Please make your purchase only after you are fully satisfied. To prevent any swapping of items, returns are not accepted, so please consider carefully before purchasing. Therefore, if there are any defects upon arrival, please only consider purchasing if you are able to handle the issue through the manufacturer. (Please understand that this is a pre-owned item that has been handled by a person.) I have reflected this in the price. This is a one-of-a-kind item, so please consider it. Seiko SEIKO ASTRON
