Seiko’s simple quartz the 7830, with just 15spm accuracy, was at the time quite distinct in its design. It was ultra flat! At just 9mm it was 10 years ahead of its time as far as quartz goes. It is fun to check this watch against its competitors of 1978 (go to birth year watches and see for yourselves). These are all “fatties” with lots of stuff ging on dial wise. This one quartz abstains, it is simple and refined - has a cabochon crown though - and it came at the hefty price of almost 1390 euro! As we all know only the Grand Quartz Diamond Dust and the Superior could demand those princely sums or more.. apparently not.
