Vintage Heuer Dashboard Timer

i came across these Vinatge Heuer Dashboard timers and looking for some insight as to the age, history and value.
thanks

The Auto-Rallye without the date (?) display and the Master-Time are late 1950s to mid 60s. Not sure about the second Auto-Rallye. These are for the American market where rally timing was in 1/100ths of a minute, not European where timing is in seconds. There is some more information here http://www.onthedash.com/Guide/_DashMounted/ and the associated forum has some regularly posting collectors of these who may be able to give an idea of value http://chronocentric.com/forums/heuer/

A look through this catalogue would give you some more information https://www.calibre11.com/catalogue...euer-1959-60-timer-catalogue/#Heuer-1950-60-6
