IWC Portuguese Tourbillon Mystère Rétrograde Watch perfectly combines the magic of a floating tourbillon with the logic of a date hand that automatically reverts to its starting position at the end of the month. With this exquisite Portuguese, you will surely attract inquisitive glances wherever you go.
The watch is powered by the IWC-manufactured Caliber 51900 mechanical movement with Pellaton automatic winding system. The 44 jewels movement provides amazing 168 hours of power reserve when fully charged.
The Dial that Instantly Draws Attention
The extra-large dial of the Tourbillon Mystère Rétrograde Watch features a graduated scale for the additional fly-back date indicator which occupies over one quarter of the dial’s surface. The fly-back date indicator jumps back automatically to “1” at the end of any month with 31 days. In the months that are shorter (February, April, June, September, November) the wearer should adjust the date indicator by activating the rapid adjustment function. In case the watch has not been worn for some time, the date indicator also must be advanced by the rapid adjustment function in order to fly back to the first day of the month. It is worth noting that the time does not need to be adjusted in conjunction with this. A retrograde date display is situated between 6 and 9 o’clock positions.

A true feast for the eyes and feature that will fascinated all watch aficionados is definitely a flying minute tourbillon set at the 12 o’clock position. The flying tourbillon boasts a steel cage with three characteristic star-shaped stays which are in charge of this function.
It is set against a deep black background which creates the illusion that the filigree cage containing the balance is rotating in mid-air. This remarkable mechanism consists of 82 individual parts and its weight constitutes 0.433 grams. On the right half of the dial, the seven-day power reserve display indicates how much energy the spring barrel is holding. The distinctive dial also comprises a railway track-style chapter ring and Arabic numerals as hour markers. The nice touch comes with the originally leaf-styled hour and minute hands.

The expansion of IWC brand has awakened the general confusion in the world of celebrities. Headquartered IWC Schaffhausen is today the site of the former orchard All Saints Monastery in Schaffhausen. Today, there are masterpieces of the top masters.
You’re right, Edward. These Swiss manufacturers produce the impressive models that deserve praise.
The museum looks incredibly good! It should be visited indeed! These are really serious watches that are made with a special technology. IWC Schaffhausen museum will be a highly visited museum.
What is your opinion about this watch ( model IW504401) ? In my opinion, it`s the best model of this watch, and in the entire collection, too. It looks very pretty. I like the watches with big case sizes, like this one.
You have the point, Harry, that model is truly the best example of pure beauty and quality of IWC watches. The designers have done a very nice job with this watch. Of course, the manufacturers have done a good job too, it`s really a quality timepiece.
I like the design of this watch, especially the transparent part of the dial. Also, I like a retrograde date display, it looks very cool, but there is also a negative side and that`s the price of the watch. It`s abnormal – $136,000 for a watch is a real madness.
