Of all the Soviet brands, Raketas are the most interesting, aesthetically speaking, in my opinion. To me, it seems like the designers were just having fun. My Raketa collection now numbers 241 pieces(!!), with my favorites being those with stone dials (jade, jasper). These were a nod to the origins of the Petrodvorets Factory.
