Prendendo spunto da una segnalazione di fabri5.5 su un calndario completo vorrei chiedervi opinioni in merito:
l'orologio è il MIH Watch:

The calendar complication devised by Ludwig Oechslin is reduced to its essential elements; nevertheless, with its ability to display the day of the week, month and date and keep track of the different numbers of days in the months, it extracts maximum benefit from the smallest number of moving parts. Master watchmaker Paul Gerber brought the calendar mechanism to series maturity and constructed the watch prototypes. This exceptional watchmaker also chose the basic move-ment for the watch: an ETA-Valjoux calibre 7750, which possesses sufficient torque to drive the calendar’s disks reliably. The calendar mechanism is entirely manufactured at Paul Gerber’s ateliers, which is also where every MIH Watch is assembled and activated. The day/date, displayed in a wide window located at 3 o’clock, consists of three concentric disks, the innermost disk showing the day of the week, the middle one the month and the outer one the date. The date disk is given an impulse at midnight by means of a mechanism incorporated in the watch’s movement. The other two disks – and, at certain junctures, the date disk – are propelled by a separate mechanism that is coupled to the hour pipe via a multifunctional intermediate gear, which makes two entire revolutions in each twenty-four hour period. This means, perforce, that two impulses are given per day, which in turn means that every day of the week is inscribed twice on the inner disk. This feature enabled the provision of a separate AM-PM display. In a month of thirty-one days, the outer date disk moves the middle disk on by one month. In thirty-day months, the middle disk’s 31st day is bypassed by receiving, in turn, an indirect impulse from the hour pipe. Due to the minimalist nature of the mechanism, the day disk is designed to change with a very slight delay.
Che né pensate?
Secondo me è molto bello semplice e con una bellissimo contatore 30 minuti (l'immagine non la trovo) sul fondo il movimento è base ETA 7750 modificato con in più la complicazione del calendario completo.
