Thanks Kasper
I saw your posts on Yéma and JAZ a few months ago whilst I was researching Framelec, which was a consortium of French watchmakers brought together in 1970 in an early attempt to thwart the growing Far Eastern (and Timex) inroads into the French watch market. Matra Horlogerie, formed as you so rightly say, at the behest of the French Government in 1981 looked like this:

Matra, a French Government backed industrial conglomerate, knew nothing about the watch and clock industry, and enroled Seiko as "advisors".
My collection is mainly mechanicals, electrics and electronics, with only a few digitals, but I'm always on the look out for interesting ones to add when I can.
