The Planetarium Table Clock: Magnificent 1775 Timepiece Tracks the Passing of Time & the Travel of the Planets

If you’re in Zurich, head over to the Bey­er Clock and Watch Muse­um, which presents the his­to­ry of time­keep­ing and time­keep­ing instru­ments, from 1400 BC to mod­ern times. On dis­play, you’ll find sun­di­als, water and tow­er clocks, Renais­sance automa­ta, and pen­du­lum clocks. And the Plan­e­tar­i­um Table Clock fea­tured above.

Made cir­ca 1775, the plan­e­tar­i­um clock keeps time … and so much more. Accord­ing to the Muse­um of Arti­facts web­site, the earth (look in the glass orb) “rotates around the sun in per­fect real time.” And the “oth­er five plan­ets rotate as well–they “go up, down, around, in rela­tion to the etched con­stel­la­tions of pre­cise­ly posi­tioned stars on the crys­tal globe, which if you are smart enough will reveal what sea­son it is.” This fine time­keep­ing piece was the joint cre­ation of Nicole-Reine Lep­aute, a French astronomer who pre­dict­ed the return of Hal­ley’s Comet, and her hus­band, Jean-André Lep­aute, who presided over a clock­mak­ing dynasty and became hor­loger du Roi (clock­mak­er to the king).

It’s hard to imag­ine that the Plan­e­tar­i­um clock did­n’t some­how inspire a more mod­ern creation–the Mid­night Plané­tar­i­um, an astro­nom­i­cal watch that shows the rota­tion of five plan­ets — Mer­cury, Venus, Earth, Mars, Jupiter, and Sat­urn. It has a price tag of $220,000 (exclud­ing sales tax). See it on dis­play below.
