Okay - so I got off my arse and looked the figures on an inflation calculator webiste. In case anyone was curious (as I was) here are the numbers in US dollars:
Seiko A159
1977 price was $145 = $520.73 in 2010
Seiko M159
1977 price was $128 = $459.68 in 2010
You were definitely "the Man" if you had one of these modern marvels on your wrist back in the '70's.
