IWC SCHAFFHAUSEN Portugieser Eternal Calendar with Moon Phase accuracy of 45 Million Years. The watch is based on the same design as the existing perpetual calendar. All its displays can be advanced using the crown. However, while the perpetual calendar is programmed for a four-year cycle, the Portugieser Eternal Calendar features an additional mechanism. Every four years at the end of February, a new module informs the calendar about whether the leap year takes place or not. This so-called 400-years gear completes only one revolution every four centuries. It contains three indentations, which cause the calendar to skip three leap years over that period. This module is designed with impressive efficiency and technical elegance and consists of only eight parts, underscoring IWC Schaffhausen’s engineering approach to fine watchmaking.
While the Da Vinci Perpetual Calendar Chronograph (Ref. IW3750) from 1985 featured a moon phase precision of 122 years, the first Portugieser Perpetual Calendar (Ref. IW5021) from 2003 impressed with a moon phase accuracy of 577.5 years. IWC’s engineers have now taken on the challenge to develop a new moon phase display with unprecedented precision.
The difficulty in displaying the moon phase on the dial of a watch lies in the fact that the moon does not follow a daily rhythm in its orbit around the Earth. A cycle from new moon to new moon - one lunation - does not last 30 days, but rather 29 days, 12 hours, 44 minutes, and 2.88 seconds. The duration of one calendar month must therefore be reduced as close as possible to one lunar cycle. This is achieved by placing a reduction gear between the base movement and the moon phase disc. The key to high precision lies in the quantity of wheels used, their proportions and the number of teeth they have. IWC’s engineers have now used a special computer program to simulate more than 22 trillion different combinations. For the Portugieser Eternal Calendar, they came up with a new reduction gear train using three intermediate wheels. Mathematically, the display will only deviate from the moon’s orbit by one day after 45 million years. Another challenge consisted in integrating this new gear train into the confined space of the eternal calendar module.
The moon phase is displayed on the dial using the characteristic Double MoonTM indication, which shows the moon as seen from the Northern and Southern hemispheres. The display consists of two super- imposed discs. A celestial disc with two small circular openings rotates above an immobile lower disc with two dots. This negative representation gives the impression that two small moons are waxing or waning. Here, the lower disc is made of titanium and decorated with a Guilloché pattern. The upper disc is made of glass.
The Portugieser Eternal Calendar features an intricately finished platinum case with polished and brushed surfaces. Another highlight is the glass dial, which is manufactured in a complex process. In the first step, the underside of the dial is frosted and lacquered in white. The subdials are machined and polished separately and subsequently fixed onto the dial. In the next step, the printing is applied, and the appliques are mounted by hand. The depth of the glass lends the print and appliques a floaty lightness. The numerals and the characteristic Portugieser minute scale are printed on a white lacquered flange sitting between the glass dial and the front glass. The box-glass sapphire crystals are machined and polished in an elaborate process. The Portugieser Eternal Calendar is fitted with a black alligator leather strap from the Italian leather artisan Santoni with a platinum folding clasp.
At work inside the platinum case is the newly developed IWC-manufactured 52640 calibre. The high-end calibre features a highly efficient Pellaton winding system. Using movements of the rotor in both directions, it reliably builds up a power reserve of seven days (168 hours) in the two barrels. Parts of the winding system that are subject to extremely high stresses are manufactured using virtually wear-free zirconium oxide ceramic. The movement has been elaborately finished with circular graining and Geneva stripes and can be admired through the box-shaped sapphire glass case back.

This outrageous watch seems to be designed and constructed on an exoplanet by an alien civilization millions of years ahead in technology…….unsurpassable. And if so only by IWC……..supercool presentation as well Alexander…..Christian
Thanks for sharing our passion!
Iwc probably my favorite brand, they just draw me in
❤❤❤Nice
the mainspring would break before it reaches 100 years even
So what?
Not really. There are many pocket watches well over 100 years old that retain their original mainspring and keep good time.
@@thomaslawrence2210 but they aren't made by iwc hahahah
Artwork of technology, mechanically something very special, unattainable until now. Simply simple and endless. Thank YOU IWC
This is a true engineering marvel. Well done IWC!
Thanks for sharing your passion with us!
Unbelieveable eternal calendar. An perfectly done again Alexander. Congrats 2 IWC.
Geniuses don’t do anything different. They do the same things differently and excel.
True! Very true! 😉 Thanks for sharing!
I will never understand why IWC isn’t further up there on the list of most respected watch makers. I love their watches, and their entire catalog. I have two, and a third may well be on the way some time soon.
Some just do and deliver... others just hype what they do... IWC is silent luxury....
They are #11 of swiss watch sales in 2023, so they are very recognized
Love that you had the CEO do the intro.
Alexander, you always have the most informative and passionate videos on the subject. Thank you as always !🍻
Holy smokes! That’s incredible. IWC calendar watches are some of the best….and now has the best. Bravo
I had to come see what Alexander thought of this eternal calendar. Forgive me if I misspelled your name
It’s spectacular of course, but it would’ve been nice to have had a bit of colour to actually make it look as amazing as it undoubtably is…imho..
Tastes are different!
How do you set it?
Love this piece of art
Through the crown as mentioned in the video…
Absolutely incredible. Can’t wait to see it and see you this week in Geneva!
It seems a lot of brands have taken TAG Heuer's glass box design this year. So far I've seen it here on this IWC Portuegeser and the new JLC Duometre.
I recently picked up the Orlebar Brown and it's a stunning piece. Now I want this watch, but I'm afraid the number may be a bit steep.
Hi Alexander. Pleased that you started with IWC and wow what an impressive watch. Hats off to IWC.
Alexander- Nice job here! Very good interview with the right person, and top information exchanged. This watch price, while quite expensive, does improve if you divide by 45 million years of enjoyment!! Keep up your great work and TOP interviews!
Superb watch. Finally some advancement in watch tech
Shear genius. Love the watch.
How much ?
Mentioned in the video… please watch it….
That is very very complicated watch IWC made, like a digital Casio G-shock
Why comparing it to a Casio??????
Nice but too expensive.
Why? How can you judge/know what the appropriate price is for such a watch?
@@WatchAdvisor Are you serious? 150'000.- is the price of a luxury car or a smaller house in the US. This is a watch and none of the materials justify the price. Putting that piece together can't cost much more than building a regular Swiss watch. This watch incl. labor isn't worth more than 2000.- .It's all about exclusivity which makes them think they can jack up prices. They and you lost all sense of proportion.
@@Seeker_of_sense We talk about the upper segment of luxury industry… other rules apply… I am sure you know/realized this
@@Seeker_of_sense This is a work of art, and a reasonably priced watch for what it can do. Don't compare it with a house or country, with this watch you buy a technological work of art
@@WatchAdvisor You are so right..
The pricing is a little steep at least for the movement finish.
Iwc is directionless. They create great dials, but it's like they're trying to sell sports watches (they're big and thick and looks like they should be everyday watches) BUT it comes with 30m water resistance and 40 something hour power reserve. Rolex just came out with the 1908 that's a dress watch that's 3.5mm slimmer, 20m more water resistance, and a day more power reserve. Also think Rolex tends to be more accurate and durable. This is comparing a dress watch that performs better than what iwc is trying to achieve
Tastes are different… I admit the 1908 is a fantastic watch…
@@WatchAdvisor yes tastes are different but if it's a sports watch or everyday watch you really want more than 30m water resistance and it should hit 2 days power reserve (using Portuguese as an example). If it's a sports watch, I think 30m you'll damage it. If it's a dress watch, it's too big. What is it going for? Comparing it to a Rolex, most models are 70 hours reserve and 100m resistance. More faith it keeps dust out too 100v30.
Also the pricing on their new models is crazy for the movement finish. They need to be in line with GS pricing.
@@jire9831 I like their dial, that's why I hope they do better. No other eternal to comp but using their most popular Portuguese (chronograph) to Daytona (which everyone knows) and iwc is 15% thicker, 24 hour lower power reserve, 70 meter lower water resistance, lower resale value AND the movement isn't as proven, finish isn't as nice.
@dannym5468 You don't know anything about mechanical watches.
