Hi
Well this a 1970 Cal 2001 IWC Quartz Electronic....using the 1st generation Beta21 movement.
Only 600 pieces in total were produced by IWC using the Cal 2001 and these were split into two distinct models , the International model (my one), and also the Da Vinci. An example of the Da Vinci resides in IWC's museum.
These were available in 18k white gold, 18k yellow gold, Platinum and SS....300 in total of these were made , so probably (as mine is SS) one of 150 or less.
Cheers Neil
