Ulysse Nardin Tellurium Johannes Kepler

Ulysse Nardin's Classico Tellurium Johannes Kepler, reference 889-70, comes in a platinum case measuring 43 mm across. The case stands 15 mm thick, a size dictated by the astronomical display it houses. Inside is the calibre UN-87, a movement built with 64 jewels for this specific complication. A sapphire crystal covers the dial, allowing an unobstructed view of the tellurium mechanism beneath. This is a limited edition, restricted to 100 pieces worldwide. An alligator leather strap completes the piece, fitted to the platinum case. Water resistance is modest given the complexity on display, with the case rated to 30 metres.
