The Upside Down is as upside down as a watch can get ! However, no need to have your head screwed on backwards to read its time. Indeed, all the numerals are reversed, except the one showing the current hour.
As soon as one hour has run its course, the numeral flips backwards, whilst the following hour instantaneously turns right side up. Therefore, 11 numerals will always be upside down, whilst the one relating to the current hour will always be right side up ! In order to render the reading of the hour even more intuitive and intantaneous, a black dot (or index) appears in front of the 59th minute of each hour.
The Upside down has only two hands, a center one for the minutes and a small second at 6 o'clock. You can't get a lot more upside down !
