Jaeger clock?

Since Chrysler had investment in Simca at one point, I would imagine a dealer in France installed that clock.

You're probably right.
I suppose that a customer asked for a clock in his Valiant, and a Simca-Chrysler dealer did install one.

The job has been properly done. A rectangular hole has been perfectly cut into the dash frame.
So well done that I wondered if this clock could be original.

A dealer installation maybe realized by this one :
