Ok my bad, i still had the sub in mind.
About the YM in your link i can say few things compared to my WM9 YM:
The dial looks to be the same as WM9, not sure if tswisstime is superlumed, probably not as this would be mentioned as a selling point.
Here is my YM, note the ever so slightly crooked 12 o clock marker. Same as on theirs.
The movement pictured is a slow beat ETA 2846. Therefor the crown position cannot be the same as the WM9 version. The base case however might very well be.
The bracelet is not the same as WM9's version:
And to rest my case, there is the hologram sticker
