Pe voi amanti degli "impossible watch",per voi sboroni che non sapete piu cosa esibire al bar,per voi che vi accingete a passare il capodanno ad un corso di orientamento notturno nei boschi artici,ecco un orologio solare che non vi può mancare in collezzione.Prodotto da Nomos costa 80-100 euro max.
Ps non ho tempo di tradurvi le istruzioni per cui,perdonatemi e adottate il "fai da te"
Ps2 l'orologio è stato concepito per essere utilizzato a latitudini di 50 gradi nord e dintorni.Per cui se abitate a Lampedusa....non compratelo eh eh eh[

To read the time it is necessary to know the approximate declination of the sun above the horizon. Therefore set the small hole in the ring to the current month on the outer scale of the ring. Then hold the ring hanging with the hole directing to the sun so that a small dot of light is being projected to the inside of the ring where time can be read off.
This handy little timekeeper shows the true local time for all places found along the same latitude as Glashütte, 51° North. For all other places around this latitude, the time shown is approximately correct, the deviation is only a few minutes per degree latitide, this is below the accuracy of reading on this timepiece so if you are not too accuracy fanatic (in this case this timepiece won´t be eight for you anyway) you can pretty well use it on the Northern Hemisphere in a belt of ca. 40°-60°N Latitude North to stay within a tolerance of about 2 light points = ca. 1/2 hour.
On the Southern Hemisphere it is working correspondingly in the belt of 40°-60°S Latitude South - all one has to do is adding 6 months one the month scale, i.e. January = Setting Juli etc.
