Hi all knowable members, Look at the picture below. According to seller it´s a watch from 1969 (2,8xxxxx). But the dial seam to be an earlier than -69. Or could these dialsbe found on later watches?
On the 166.024's (date version) both the BT dial and the normal 12 o'clock dial are ok. Both early and late serials. And regardless if it is a 166024-67 reference or straight 166.024 reference. Serial 28x is the latest for these and depending on the precise serial and sub/no sub-reference and if it's a US version (cal. 563) or not (cal. 565) it would have been produced late 1969 or in the first half of 1970. But yes, let's get some more info and pictures, and you will get more precise answers
