Two "Blonie" (small town at the outskirts of Warsaw) products of the fifties/sixties, the "Baltyk"-s (meaning Baltic sea, of course). Content of Soviet parts was to be reduced, new machines were purchased in Switzerland, then Big Brother decided Poland does not need watch factories and generously bought back at fraction of cost the machines.
WODOSZCZELNY means "watertight" (not "waterproof", that would be WODOODPORNY).
