I only see two but I'm a beginner....last month I probably wouldn't have seen any.

 

What it says Railmaster on the front and Constellation on the back

 

so, is that 2 or 1

 

I'm going for completely wrong movement, the dial says co-axial the clear caseback shows something that isn't

 

just taken a look at a real one and maybe I was wrong there....

 

I counted the Railmaster-Constellation as one. Front says 150m, back says 100m.

 

It is a little bit strange. while the front looks fine, the back is something different.
Mine shows Aqua Terra instead of Constellation, and the movement Cal 2403 looks slightly different. I'll take picture when I could.
