Regarding numbers produced (18k only), Omega usually only release figures for calibre production not individual variants, my guess 100-200 units. Omega were in the habit back then of producing the first of a new calibre in 18K only, and for some strange reason used to produce in batches of circa 50 units - usually entrusted to Fontana in Italy, not Star as you might expect (some sort of prohibitive tax,import problem perhaps ??)( 18K TC1 initial order =60 units, 18K Electroquartz -the predecessor to the Megaquartz, initial production =42 watches,all 42 sold before the end of the 1970s Basel fair at 5,400CHF ea )

Here's how spectacular the dial can look if you catch it right
