Thank you for viewing my listing from among the many available. SONY SmartWatch 3 Core Holder, Leather Belt for Core Holder, and EZIO Holder for Core Holder. 【Core Holder】 Manufacturer: SONY Product Name: SmartWatch 3 Core Holder Model Number: SWR510C Color: Black (This product is only available in black) 【Leather Belt for Core Holder】 Manufacturer: SONY Model Number: Not for sale Color: Brown (belt) / Black (buckle) The core holder is rare and difficult to obtain as an accessory for the SmartWatch 3. I purchased it new and have used it a few times, but there are no noticeable scratches. Also, the leather belt for the core holder is genuine SONY, but it is not for sale and is even rarer. I purchased it on an online auction, and I obtained the core holder to match it. I used it once and then stored it. It is a used item, and there is some wear on the buckle holes. I will include a holder (EZIO) that allows you to attach the core holder to a pocket watch or a bag. (Photo 9) 【SmartWatch 3 Holder】 Manufacturer: Faze In Limited Brand: EZIO How to use: Attach the SmartWatch 3 to the core holder (SWR510C) and secure it in the holder. There are no original boxes for any of these items. Although the number of SONY SmartWatch 3 users is limited, I am listing this product in the hope that someone who loves this product will use it. Please consider purchasing with the understanding that all items are used, have a small amount of usage history, and returns are not accepted to prevent swapping, etc.
