The Portuguese (or Portugieser) observe family currently incorporates a model including huge twofold digit shows for the date and month: the IWC Portuguese Perpetual Calendar Digital Date-Month Edition “75th Anniversary” (Ref. 3972).

The hour and moment chronograph counters are combined in an aggregator at 12 o’clock.

Toward the month’s end, when the strain in the spring has arrived at its most extreme, it is the ideal opportunity for all that energy to be delivered; the brisk activity switch hops momentarily to its beginning position and advances both of the month show circles separately, or together, by one position, contingent upon the month. On 31 December, the jump year circle is likewise exceptional simultaneously.
