The description at pure time seems to be wrong, but I am not 100% sure. The still mention the nh35. Intime especially says that the movement does not have the stuttering anymore. That’s why I guess the description is wrong at puretime.

One of them is wrong, my bet is on the description with the 6T28 being incorrect, for several reasons. First, the movement is visually identical to my Yas Marina. Second, while the 6T28 is an open-heart watch (and shows the balance wheel), it's 2mm larger than the Seiko meaning the proportions are off and it may not fit into the case or hide behind the deco. Third, the stuttering wasn't caused by the beat rate, but by a slipping spring on the seconds pinion, as someone on here showed in their post a while ago. This stuttering is present on the 35s and the white Bubba 55, but not the Yas Marinas or White Legends to my knowledge and experience, so while a higher beat rate would indeed move more smoothly, it does not cause the stuttering issue and that issue appears to have been fixed. Fourth, when the Yas came out one of the TDs had the same incorrect description with a different movement, which seems to have been just a modded Seiko. Either the switch happened when they made the Yas or the movement is the same amongst all of the variants.
Looking forward to someone opening it up and figuring out exactly what's in there!
