The latest addition is the Heuer Carrera "Fisher" ref. 2447 D from ca. 1968.
This watch was ordered by- and deliverd to Fisher scientific laboratories. There are not that many "Fisher" Carreras out there and all the ones I have seen (in pictures) so far have are "D-versions" i.e. with the decimal scale.
My hunt continues with the goal to find a "Türler" and a "Güblein"
