The family (Du Bois) sold the company in 2010 and it re-launched in 2013 with a crowdfunding project. Hence the change in direction.
The watch does not look like it is in bad shape a service and new glass will give you a nice family heirloom. The value is in the story more than anything else. Many on the forum ,including myself, would love to have a watch that was handed down to them. With a standard ETA 7751 servicing should always be ok. Overall a good wearable watch, I would say wear it and enjoy.
If you are looking for a value eBay usually has a few for sale, that will give you a guide. It would depend if it was gold or gold plated. If the caseback is steel then it more than likely gold plated.
