Sihhpremiere: Portuguese Annual Calendar by Iwc

The IWC Portugieser year calendar reference IW503502 rests dial and stainless steel case. By 2015, it celebrates premiere at the SIHH.

So far there were Portuguese watches from IWC with date display or with a perpetual calendar. A yearly calendar of missing watches fans so far. On the Geneva Watch fair in 2015, the Swiss will close this gap.

The Gregorian calendar with its different month lengths is a challenge for the watchmaker.Earlier the clock makers had to manually correct the display always at the end of the month, if the month had fewer than 31 days. Thanks to several discs in the movement this more monthly is not necessary of IWC watch in the annual calendar of the new Portuguese.

IWC on the SIHH 2015

In contrast to the eternal calendar the IWC must be set February hand Portuguese with annual calendar – 2015 celebrating premiere at the Geneva Watch fair - but once a year at the end of the month. The complication that knows no leap years and months with less than 30 days. Fortunately, the correction mechanism designed but pretty easy over the Crown, it could be dispensed with even the push at the edge of the housing, which would have affected the clear appearance of the Portuguese.

Three Windows are centered at the twelve o’clock position on the dial of the Portuguese annual calendar placed, one for the month, one for day and one for the year. The order American-style is deliberately chosen: it should be a tribute to A. Jones, the American founder of IWC. By their white deposit and its relatively large size, the readability is very good. The indexes ’11’ to ‘1’ were replaced by however for reasons of space.

Lush: a week duration

A factory works with a very lush course duration of seven days in the annual calendar of IWC Portugieser. Two barrels provide enough power. The work of the caliber of 52850 can be observed through the sapphire glass back of the clock. The construction of the calendar took by the way about five years; also, because the IWC could fall back on no in-house experience here.
