Perhaps they have used difference versions in different batches.
Here is a photo of the movement in the Noob V10 that Logixa reviewed in October 2019, which shows the SA3135/VR3135 movement:
Most likely it is not about updating, but lots. Unfortunately we can't see pictures of the mod in QC, so it's the same as playing the lottery when buying a Noob V10. Mine unfortunately came with the SA movement (old) and I could only know it was this movement because my watch was a problem and I had to send it to a watchmaker here. The clock stopped running when the rope was activated. I had to shake it to get it working again.
