Hamilton Pulsar wristwatch. The battery was replaced 7 years ago, and only the operation at that time has been confirmed, so it is being sold as a junk item. It was a digital watch with a very cool red light. The inner circumference of the belt is around 16cm. No smokers, and I have a cat. For those who understand used items, No claims and no returns. If you have any questions, please feel free to ask. - Brand: Hamilton - Color: Red/Silver - Material: Stainless steel - Design: Digital display/Round - Band type: Metal band Thank you for viewing.
