I have a number of watches with the ESA logo on the dial. It is thought that these were either demonstration or training watches.

Firstly, I bought this ESA 9150 movement to be used for parts but was surprised to see the dial when it arrived. It has the ESA logo and the word "Dynotron" on it:

Secondly, this ESA 9162-based tuning fork watch also has the ESA logo on the dial and a dedication on the reverse; inquiries to-date have not revealed the meaning of the dedication:

ESA Branded tuning fork watch; all stainless steel case; 1971

ESA 9162 movement

Snap-on compressor back

Roger Payot dedication

Finally, a Landeron 4751-based watch with the the ESA logo on the dial; Landeron was an ESA company:
