Vintage Wittnauer Duchess goldtone watch still in box

This is a Wittnauer quartz watch. This is still in the original box, with the original tags. This box has no papers. I have not opened the watch to replace any batteries as the little booklet that comes with it says opening the back affects the water resistance and all this, and I am not confident in my watch abilities. The original tag is for $180. Inside of the watch band reads Duchess USA 1/40 10K RGP mesh St. Clasp. There is still a sticker on the back of the watch. I love vintage stuff in original packaging. It's so fun!
