Echoing the pocket watches converted into wristwatches in the early 1920s, the new perpetual calendar by H. Moser & Cie. Moser & Cie. It features a round case, a notched crown, and a deep blue dial in grand feu enamel punctuated by Roman numeral hour markers and swallow-tailed hands. The hand-wound HMC 800 manufacture movement with double barrel for a 7-day power reserve can be admired through the transparency of the sapphire porthole on the back. It can be set forwards or backwards at any time of the day, and thanks to the Flash Calendar system, the date changes instantly at midnight, taking into account 30- and 31-day months and leap years. In a limited series of 20, the Heritage Perpetual Calendar Midnight Blue Enamel features a white gold case with blue enamel inserts on the case middle and a midnight blue alligator strap. Price: 99,000 Swiss francs.
