: I have seen some of these. They are not pré-Carrera. This is a
: three register version of the economy model range. The case is
: not the same as Carrera. This chrome case is the same as the two
: register economy models and is also used by poor mans Heuers
: like Clebar, Hamilton, Zodiac and Tradition/Sears.

: Heuer ref 3641 chrome case economy model. There's several versions
: of these chrome cased economy chronographs from the late 60's to
: the 70's.
