To mark its 25th anniversary, Hermes has released the 'Arceau Petite Lune'. A new interpretation of a watch first designed by Henri d'Origny all those years ago, the modern style has a shiny white mother-of-pearl dial and elegant Arabic numerals. As well as telling the hours and minutes, it also has two further complications: one for telling the phases of the moon and lunar cycles. This one has a deep indigo alligator strap.
