nine I became curious, why are you giving a 6 out of 10 score to the v6F case? There was a review from a member making a comparison between the GEN seamaster 300 coaxial and the v6f spectre (gen cases are the same) and teh review conclusion was that other than color and material of the bezel case is literally 1:1 in dimensions, same thickness, same lug shape, same caseback, bezel ceramic insert font was sliglty different and the black was darker, the rep was candidate to rep of the year!
So not quite sure that a 6 score its really fair with this rep, if the new one has a better movement (that was the most common complain about the miyota "stuttering" second hand) we will see what this new reps come up with.
so far i have seen several spectres from aliexpress and that quality is way different from the v6f.
