The setting that turns on the light when you tilt the watch is practical! How about it for a night walk with your dog?? It's a stylish and popular design. I don't have a dog! I think a lot of people thought that, right? This watch is blue, so it helps you stay calm when you wear it. It helps you when you want to calm down. The design isn't too busy, and the exquisite blue is a great touch! I think it's good for exams and studying. The battery is new, and grease has been applied. *2025.9.24 Operation has been confirmed, and the light works without any problems. I hope you can purchase it with confidence. You can use it for a long time. The troublesome time setting has also been done, so you can use it as soon as it arrives. I think the product is in very good condition (subjective). I want to say it's almost new! I took photos with the strap removed because I thought it would be easier to see any scratches or scuffs. Please check them. *The product will be shipped with the strap attached. Are you going to study hard?
