Look again at the highlighted hour markers...the dial _is_ tilted. I think possibly that's due to the movement mods required for the two sub-dials, but I'd have to check another example to be sure.It gives the illusion that the entire dial is tilted. IIRC, the description of the Raketa was 'motorcycle watch' i.e. it is tilted to make it easier to read while riding a bike. I doubt if that is the true reason for it, but it makes a good conversation starter.
