The 35mm Saxonia loses out to the Saxonia thin, not only due to more visible parts being shown on the Saxonia thin but if you place both watches side by side, you will notice that the dial of the Saxonia thin has a deeper an richer patina. Yep, they are not the same colour and kudos to Lange for making it different when it would have been simpler to have the same coloured dial for both watches. Both watches have a 72 hour power reserve and my main concern now is the number of barrels used in the Saxonia thin. If the watch has only one barrel, it will mean way too many turns to wind the watch (I had this unfortunate experience with the 1815 up and down). The little Lange 1 though is equipped with two barrels.
