Ulysse Nardin Marine Mega Yacht

Ulysse Nardin's Marine Mega Yacht, reference 6319-305, comes in a 44 mm platinum case. The dial, in grey and blue enamel, sits under a sapphire crystal. Inside is the manual-winding calibre UN-631, offering 80 hours of power reserve. The watch is a limited edition of thirty pieces, fitted with a flying tourbillon and a moon phase display, and a power reserve indicator sits on the dial as well. An alligator leather strap closes the piece. Ulysse Nardin rates the case to 50 metres, modest for a watch built around such elaborate mechanics rather than diving.
