as the dial options are almost limitless whereas with the AK-06, one would have a choice of two dials. Also the dial of the AK-06 is more niche as lovely as it is. For the record, I too have been considering the AK-06 against a Vingt 8 and the latter makes compelling sense. The movement design on the Akrivia is superb with its perfect symmetry. I will go out on a limb here to say that Kari's movement finishing is slightly better than Akrivia's ie Kari is more consistent.
