Thanks Gentlemen.
I'm not sure why I thought it rotated. Perhaps this is just what I thought it
should do

.
I thought it was pretty rare. Your one is the only reference I can find on the net.
It had a BIN price, but I waited for a shipping quote before pulling the trigger. I was a bit anxious waiting for the quote, but it was so poorly listed that I was reasonably confident no-one else would snap it up. It did have 53 views though ............perhaps people didn't properly recognise it, perhaps the condition put a few people off, or perhaps it had been viewed by non-LED collectors

.
Anyway, I can see a few difference between mine and yours:
1. Obviously mine is in French, yours is in English.
2. Yours has a base, mine doesn't.
3. The left vertical side on yours wraps back under the top section for attachment to the base. Mine doesn't. It's cut-off early. Not sure if it's broken, or if it's meant to be this way. It looks like a nice clean cut/edge though.
3. The horizontal part of yours directly under the watch holder has the corners cut off on the left side so that it forms a wedge shape. Mine just ends at 90 degrees. (or is that just a shadow ?)
4. Mine looks to be a purple plastic colour, yours looks to be timber or some sort of faux-timber.
Since mine doesn't have a base, perhaps it was intended as a more generic display stand (i.e. the base shows the specific intended model). That is of course if mine never had a base !
I guess it will become clearer when it arrives
