His includes the date jumper spring. Also after messaging him about the specific issue, he claimed to have available either a DD (VS) or an SH (VR) part. So I asked for the SH part. If it works, I will order two more for my total of three affected VS3135s.
UPDATE:
Using the SH/VR date plate from the vendor above, I was able to achieve a normally centered DW. But there is a caveat - more on that later.
First let me state that in all the previously posted VS pics and the first two repeated here below (blue dial), the DW used is a Raffles aftermarket. It was changed to that to see if it would fix the stock VS movement / date plate / DW flaw that is the topic of this thread. The change to this known good DW did not fix the flaw.
The replacement SH/VR date plate was installed to the VS3I35. While I was at it, and thinking it would be fine I reinstalled the stock VS DW to the new SH/VR date plate.
Initially I was like Yay it's fixed!
But after rotating through some dates I saw that dates on the other side of the DW were low again, WTF
After examining the VS DW again it appears to me that its bare outer perimeter rim (common to nearly all clone DWs) allows for some looseness of fit within the DW detent. This permits the DW to shift high or low during its rotation depending on which anchor post is tighter or where the wheel is slightly thicker, etc.
So I switched the Raffles aftermarket DW back in and it does not exhibit this issue, all the dates are adequately centered. The Raffles 3135 DW is quite nice, which is why I have it. In fact I bought it for this very movement. It's also painted all the way to the edge, making that last 0.5mm thicker than a rep DW so there is less looseness.
So there it is - it took me BOTH a VR date plate and a different DW to get a complete fix. Pretty sad but we do what we gotta do, right? Nowadays I immediately look at DWs in rep pics with a VS3135 and there are a lot of low sitting dates out there. DD needs to step up its game in this area.
