Descrizione
Stepped case lugs emphasize the play of light and shade for a sharp look, and the indices are separate metal parts for a better texture. The hands have been redesigned and fitted with LumiBrite for better visibility, including at night, and the sapphire crystal has a Super Clear coating that reduces reflections and resists smudges. An electronic crown makes time zone correction easier, and the watch receives standard time signals from 6 stations in 5 areas (Japan, China, the US, Germany and the UK).
