IWC Schaffhausen continues to celebrate its 150th anniversary in 2018. Most recently a new edition was added to their “Portugieser” model line. At first glance this platinum model, looks almost identical to previous editions. But, they’ve swapped calibers for this new “IWC Portugieser Perpetual Calendar Platinum”.
One of the main novelties on this “Portugieser” is it being the first in the current collection to be paired with Kurt Klaus’s perpetual calendar mechanism. We must recall that the Klaus perpetual calendar was engineered to track the: days, date, and month without needing to be reset until the year 2100. It was originally conceived and included in the more modest Valijoux 7750 caliber movement, but IWC now presents it as their in-house caliber 52615.
The 44.2mm case that houses the novel caliber is made out of platinum with a transparent case back, which allows to view the inner workings of the mechanical movement. Behind the exhibition case back are visible scattered jewels and an 18k rose gold rotor with the IWC logo and a “7 DAYS POWER RESERVE” engraved inscription.
It comes equipped with a setting-crown that has also been pre-programmed to be in sync with the calendar, but it can only wind forward. So, if the calendar is advanced beyond the current date, resetting it will require a trip to the service center. A convenient feature that can also become a costly hassle if the user were too mistakenly over wind. All topped by a sapphire crystal that assists with water-resistance on this watch reaching up to 30 meters (98 feet).
Time is exhibited on a silver dial with platinum applied Arabic numerals and central hands; plus a rail-road motif ring of smaller minute index markers, with a slightly larger marker for every 5-minute increment. There are also four sub-dials: a calendar with a 7-day power reserve in its midst at the 3 o’clock position; a month dial at the 9 o’clock position; a day of the week dial with a sub-seconds in its midst; and a double Moonphase indicator at the 12 o’clock position.
The Moonphase here is represented in a darker blue with platinum colored stars and two synchronized Moonphases, one for each hemisphere with an “N” and “S” marking for “North” and “South” by them. There is also a four-digit year display located between the 7 and 8 o’clock positions.
