There's a clip on the back, and it's a reel type, so the watch part stretches out when you pull it. You can change the orientation of the watch to your liking. It's larger than it looks in the picture, and the panda design is quite prominent. I use a different pattern for work, and it's well-received and easy to see, so I really like it. It's made of silicone. I think the battery is for testing, but the one I'm using has been working for about 4 months now. When the battery runs out, please have it replaced at a watch shop. There is no warranty, but a simple instruction manual is included. Since it's an inexpensive product, we cannot accept returns for initial defects with the buyer paying for shipping. We will buy it back if you relist it with a markup for fees, etc. If you wish, we can check the operation (remove the stopper) before shipping. We do not charge duplicate fees, so please consider combining it with other products. We will calculate the price as the amount listed in the image + 180 yen for shipping.
