Seiko Lady Platinum and Paladium

A very collectible seiko.
there are little knowledge about platinum seikos, i only know credor platinum after year 1990.
this watch approximately produced from 50s looking at elements at caseback. It is really a seiko caseback. I will update with movement and another detail later.
Caseback contains words 650 platinum and 350 palladium which means the case made from platinum and palladium. That would means the case made from precious metals. Even though this is seiko and not swiss watch, therefore no manufacture detail (and hallmarks) at caseback. I believe there are another platinum case vintage seiko yet to be found

size 12x32mm

all original
