Explanation:
In marketing, brand leverage is a strategy used to add value to a new brand by associating it to existing brands. In this case, some Swiss watches are world famous for being excellent and very expensive watches, e.g. Rolex, Omega, Piguet, Patek Philippe, etc. So what this salesperson is doing, is associating this unknown watch to other Swiss watches and therefore claiming that it must also be a good watch.
The same happens with cars, e.g. Volkswagen are cheap entry level cars in most of the world, but in the US they are branded as German cars or built with German technology, associating them to high quality cars like BMW or Mercedes Benz.
