Agree with David -- "Heuer" Alone on the Bridge is a Problem

So I just looked at photos from around 30 Valjoux 92 movements, divided evenly between Autavia 3646 and Carrera 3647 chronographs.

Agree with David, that we should see either ED. HEUER & CO SA (pre 1964 merger) or HEUER LEONIDAS SA (post 1964 merger). To see "Heuer" alone is a problem.

The "MN" code is OK . . . seems to indicated a Valjoux movement to be used by Heuer.

: Also wanted to add, I've only ever seen the bridges of Heuer
: Valjoux 92 movements with either HEUER LEONIDAS SA (post 1964
: merger) or ED. HEUER & CO SA (pre 1964 merger). This is is
: the only Heuer 92 I've seen with Heuer only on the bridge. Could
: it possibly be a franken-movement?
