Nice watch, but I still don't get this watch completely,
Hi Suitbert, all,
From the press kit:
Real solar time and mean solar time coincide only four times per year, at approximately the 16th April, 14th June, 1st
September and 25th December. On these days the blued steel minute hand and the yellow gold hand will converge.
The first is true only for standard meridians. So on those 4 days if you are not located on a standard meridian the yellow gold 'sun' hand wil not indicate true solar time for your location, in fact it will never indicate the true solar time correctly for any location off the standard meridian.
Provided the blued steel hands of the watch are set on the local solar mean time i.e. the official time corrected according to the longitude deviation, one can intuitively read at a glance the real solar time by means of the hour blued steel hand and the gold sun hand.
This part I don't understand. What is meant by the local solar mean time i.e. the official time corrected according to the longitude deviation? Do you have to set the blue hands such that the only difference between the blue hands and gold sun hand is the EOT? If that is the case the sun hand indeed indicates true solar time, but the blue hands indicate a non-existent time (if not located on a standard meridian) i.e. it will not indicate mean solar time nor true solar time.
Now if you could set the sun hand yourself the watch could indicate both true and mean solar time, but the difference between both hands will, for most locations, not be the EOT (which, imo, would be the best solution. Perhaps then it could also indicate the EOT on the back).
So, what is going on here? 
Regards,
Joram
