An elegant watch
At the first glance, it is a feeling of elegance that stands out of this IWC.
The very beautiful alligator strap, the grey gold casing, the very dark and changing blue dial as well as the dial finishing are perfectly controlled.
The grey gold bears its name wrong…
It indeed offers very warm reflects, distilled with parsimony thanks to the brushing of the straight parts of the casing as well as the rounded parts of the bezel or the back of the casing.
This finishing, combined with the design of the lugs, lives down the thickness of the watch.
This impression is confirmed once the watch is around the wrist, where it finds its place and could even be forgotten, as long as the wrist is not too small !
A harmonious dial
The dial happily plays on the finishing and the aspect.
Trademark of the brand, the opening of the dial is very wide and the time is perfectly readable.
The sub-dials allow a complete display of the calendar, the power reserve, and the moon with its phases as well as the number of the days before the next full moon.
In order to allow a good readability of all the available information, IWC worked very finely on the contrasts of the hands and the sub-dials.
Only drawback : the aperture of the year and its discs lack of discretion inside of a very harmonious dial.
On the other side of the watch, the caliber 51614 unveils itself very widely with a sapphire back that seems huge – for our great pleasure.
Once more, the realization is beautiful and well accomplished.
It allows seeing the oscillating weight with the Probus Scaffusia locket, the automatic Pellaton self-winding system, and the barrel that allows a 7-day power reserve as well as the vibrating balance of 21.600 alternations per hour.
Little regret : the modular conception of the caliber puts indeed the complication on the dial side and make thus invisible the specificity of this wonderful model.
Finally, the perpetual calendar is a very accomplished and delicate complication that IWC completely controls insomuch that it provides a substitute aperture that allows the display of the year until 2499 !
Accompanied like here by a 7-day power reserve, by a calendar setting by the crown, it nearly allows to believe that it is a normal watch.
Be careful nevertheless when setting the date : the system does not allow going back.
What to remember
With this new Perpetual Calendar Portuguese, IWC gives a rare watch.
Despite important sizes, the interest of the complication, the pleasure to wear it around the wrist and to watch it prevail to a large extent.
