This is a new, unused item. It's a stylish pocket watch with a chain. It's quartz. The dial diameter is 4.5 cm, and the chain length is approximately 80 cm. The crown is pulled out, so please turn it to set the time. When you push the crown in, the second hand will start moving. There is a protective film on the crystal, so please peel it off before use. Pressing the button at the top with a click will cause it to pop open. The feeling when closing it is addictive ^_^ Recommended for those who like something a little different. Thank you.
