ll the solutions proposed so far don' meet the criterion that the clock not be software. It's too esy to make a software display. yu just start with UTC and apply a formula from an amanac.
But what was requested was something made with gears and springs I wonder if you really need a special clock? Can't you adjust a normal spring driven clock to run fast (or is it slow?) by about 1/3 of a percent (one day per year)? This should be within the range of adjustment. So take a normal clock and go outdoors at noon and look at your sundial. Set the clock to 12:00 at local noon. Then the next day check again and adjust the lever on the rear of the clock to make it go faster or slower. After a few days it should work.
