A couple days ago I received a pocket watch. My granddad's granddad bought it a long time ago and my granddad decided to give it to me.
On the front it says that it's a Tiffany & Co watch made in Switserland. But when I open it it says "made for Tiffany&Co by the Longines watch Co."
I'm not exactly a watch expert and I'd like to know how much this watch would be worth.
