The original Piaget Black Tie: as Classic & Cartier-esque as it gets. And next to its contemporary style and size (43mm ex crown) it is not only the 1st Swiss quartzwatch Beta21 and thus an important horological milestone but also the Beta21 made in highest quality of all brands -- neither Omega nor Patek comes close. And if Cartier would have been part of the Swiss Center of Electronic Horology (C.E.H.) and would have created a first quartzwatch in 1970 (it did not), then it would have looked quite similar for sure: outside classic and inside technological avant-garde.
