Warmet - a famous Warsaw factory with branches throughout Poland. It was established as a result of the nationalization of private enterprises in 1951 and their further transformations, including into Wytwórnia Wyrobów Jubilerkich.
It has been known by its current name since 1969 when Wytwórnia Wyrobów Jubilerskich (from which the famous "reed" - Warmet's signature made up of the letters WWJ) was renamed the Precious Metals Products Factory "Warmet".
