5990/1A with khaki/sand dial
5164T with semi skeletonized dial and movement details finished in dark gray tones
5170A with green enamel dial
A steel Calatrava with new in-house manual movement and no date, just three hands and central seconds.... like a modern 570...
Dreaming dreaming dreaming... but a 5164 like this along with any one of the two last ones would probably satisfy me for a two watch setup...
