Hi buyers!!! You are buying a Vintage Pulsar Gold Plated Day/Date Quartz Men's Pocket Watch Chain/Knife, it's new old stock. The owner had it for a long time and never used it. The inner case has engraving, I took a picture for you to see for yourself. I put in a new battery, so you will be able to use it right away. Please follow me, I will add more listings every week...Thanks
