Great watch, I've seen Certina Audi Design Quattro 1980 on sale, but it's expensive: 850 euros. I used such watches but took them much cheaper. In General, there are a large number of stores that sell quality watches. I am a collector of watches, especially classic ones. It is important to check the manufacturer before buying, this can save you from forgery. At the world market there are a lot of fakes from world manufacturers of terrible quality. Be careful when buying, so that you do not regret your money later, watches are not cheap today.
