Like the rest of the legendary family, the 2010 IWC Portuguese Tourbillon Mystere Retrograde (Ref. IW5044) sports an oversized case and is powered by a huge automatic movement that offers you as long as a whole week of guaranteed power supply.
Compared to a trifle less expensive 2010 Portuguese Tourbillon (Ref. IW5447) that is powered by a hand-wound mechanism, the Tourbillon Mystere Retrograde (Ref IW5044) features a much more balanced (although still a bit too busy) dial.
Available both in anthracite and silver, the former goes with an ultra-expensive version with platinum case (Ref. IW504401) and the latter comes with a more affordable (if you can use the adjective when it comes to top-of-the-range watches from IWC) body crafted from rose gold (Ref. IW504402.)
As I have already mentioned, the cases are large for what is essentially a dressy timekeeper. Being more than 44 millimeters in diameter and 15.50 mm thick they look bold and even defiant, drawing too much attention from other people, but, let’s admit that, giving the customers what they want: a large, ultra-expensive timekeeper that is supposed to draw attention to its owner.
Well, I must admit that the watches are still a pleasure to look at, although I prefer timekeepers with more symmetrically aligned dials.
Besides the tourbillon that took place of the usual small seconds sub-dial, the IW5044’s main points of attraction are the retrograde date indicator with contrasting bright-red numbers between 7 and 8 o’clock and the 7-day power reserve display. As usual, there is no Superluminova on any of the indicators, but that’s okay: after all, it’s a watch you are supposed to wear at cocktail parties and business meetings and there is usually plenty of light there.
The IWC Calibre 51900 that animates this piece is manufactured in-house and is based on their less sophisticated cal. 5011 workhorse movement. Being essentially a three-hander with a complication module stacked atop of it, the mechanism may not be as sophisticated and unique as those calibers that are created from scratch, but, given how small is the market for ultra-luxury watches, it also allows the Swiss manufacturer to limit the timekeeper’s development costs at more or less manageable levels not letting it skyrocket out of control.
Still, the collection is very expensive. Limited to only 250 and 500 pieces for the model in platinum and rose gold respectively, the Portuguese Tourbillon Mystere Retrograde will retail for around $135,000 and $115,000 US dollars.
