This is a BUREN wristwatch. It's a Swiss watch. It's a vintage manual winding type. It works, but I think it would be better to have it overhauled. There's a 20k marking, so I think the gold parts are 20 karat. I'm not sure because the markings are unclear, but it's a watch with a delicate and beautiful design, so I'd like someone who likes antiques to use it. The strap is not genuine. Returns are not accepted. Please consider this item if you understand that it is a used item.
