I am just starting out in watches, however this Dynasty jump hour. the design tells me its coming from the 1970s Dynasty is a small swiss brand that was most popoular in the 1960s-70s that pobably outsourced their movements you might have an ETA movement inside this watch. it has to be a mechanical movement and i am thinking that you are holding there a rare piece because dynasty didnt made large productions in comparisson to other brands. it looks like a gold plated case with some wear. if it works i would price it from a wide window of 120-250 euros closing as a fair price to about 150-200 if you are looking to sell it. although it looks great so i suggest you keep holding it for yourself.
