It is the main talking point when it comes to perpetual calendars. The upgrade here isn\u2019t just the new Code 11.59 Perpetual Calendar itself. It is actually the self-winding calibre 7138. After being engineered during 5 years and receiving 5 patents, the manufacture has reimagined thoroughly the ergonomics of this complication. This project relied on both a simple and ambitious aim: allowing the wearer to adjust every function, using the crown only.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.my-watchsite.fr\/blog\/wp-content\/uploads\/2026\/06\/ap1.jpg\" alt=\"\" class=\"wp-image-49392\" \/><figcaption class=\"wp-element-caption\">The Perpetual Calendar on this Code 11.59 by Audemars Piguet is adjusted entirely thanks to a &#8216;single-crown&#8217; system.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Managing everything just with the crown<\/strong><\/h3>\n\n\n\n<p>No more case-side correctors, but a 4-position crown instead. Depending on its position and the way it is turned, you can sequentially set the date, month, leap year, day, week number, moon phase, and time. Your daily wear becomes smoother, and the risk of desynchronising the calendar or damaging the movement because of a stray adjustment is starkly lowered. This setup also gives a cleaner feel to the 41mm white gold case. Without case-side correctors, the Code 11.59 features a much refined look. Furthermore, it is water-resistant to 30 metres.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.my-watchsite.fr\/blog\/wp-content\/uploads\/2026\/06\/ap3.jpg\" alt=\"\" class=\"wp-image-49398\" \/><figcaption class=\"wp-element-caption\">The smoked blue embossed motif highlights the dial, thanks to the PVD treatment.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Enhanced legibility<\/strong><\/strong><\/h3>\n\n\n\n<p>Upgrading movement\u2019s ergonomics was only the first step for the manufacture. Indeed, the dial has also been revamped for enhanced legibility. The displays now follow a more intuitive order, with the day at 9 o\u2019clock, the date at 12 o\u2019clock, and the month at 3 o\u2019clock. A 24-hour display, part of the day sub-dial highlights the 9 pm to 3 am window in red. It shows the period during which the self-winding calendar change occurs. Besides, the moon phase takes up a perfectly centered position at 6 o\u2019clock.<\/p>\n\n\n\n<p><strong>A technical showcase above all<\/strong><\/p>\n\n\n\n<p>Beneath the sapphire case back lies the calibre 7138. Measuring a mere 4.1mm thick, even with 422 components, it beats at a frequency of 4 Hz, for roughly a 50-hour power reserve. A worthy successor to the developments spearheaded on the Royal Oak RD#2, the movement highlights a design which displays all calendar functions onto a single level to preserve an exceptionally slim profile.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.my-watchsite.fr\/blog\/wp-content\/uploads\/2026\/06\/ap2.jpg\" alt=\"\" class=\"wp-image-49397\" \/><figcaption class=\"wp-element-caption\">The crown features 4 special positions.<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-pullquote has-border-color has-text-color has-medium-font-size\" style=\"border-color:#749fbc;border-width:4px;color:#749fbc\"><blockquote><p><strong><strong>The &#8216;single-crown&#8217; system<\/strong><\/strong><br><strong><br><\/strong>\u2013&nbsp; <strong>Position 1:<\/strong> Winding the timepiece clockwise.<br>\u2013&nbsp; <strong>Position 2:<\/strong> Pulling the crown out by one notch allows for clockwise date adjustment, alongside anti-clockwise adjustment of both the month and leap year.<br>\u2013&nbsp;<strong>Position 3: <\/strong>Pulling the crown out once more allows the time to be set in either direction.<br>\u2013&nbsp; <strong>Position 4:<\/strong> Pushing the crown back in by one notch allows for clockwise correction of the day and week, and moon-phase adjustment in the opposite direction.<\/p><\/blockquote><\/figure>\n\n\n\n<p>The smoked, embossed blue dial \u2014 crafted from a hand-engraved motif by Yann von Kaenel \u2014 brings the hallmark aesthetic touch of the Code 11.59.

Back in 1985, IWC made waves with Kurt Klaus\u2019s ingenious system, which allowed all indicators to be set easily thanks to the crown. Four decades on, the manufacture is going the extra mile with the IWC-ProSet\u00ae Perpetual Calendar, a complete revamp of the timepiece settings.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.my-watchsite.fr\/blog\/wp-content\/uploads\/2026\/06\/iwc1-3.jpg\" alt=\"\" class=\"wp-image-49413\" style=\"aspect-ratio:0.6206896551724138;width:600px;height:auto\" \/><figcaption class=\"wp-element-caption\">The Big Pilot\u2019s Perpetual Calendar ProSet Edition &#8220;Le Petit Prince&#8221; is fitted with a 43mm white zirconium oxide ceramic case.<\/figcaption><\/figure>\n\n\n\n<p>The real breakthrough lies in its fully synchronised, gear-driven architecture. For the first time in an IWC timepiece, the calendar is adjustable both forwards and backwards simply by turning the crown. No more correctors, no more convoluted setting sequences: the date, day, month, year, and moon phase all follow the crown&#8217;s movement in perfect harmony. This upgrade makes living with this complication day-to-day much smoother. This mechanism still automatically accounts for 30- and 31-day months, as well as leap years. It was also the opportunity for the brand to update the Double Moon\u2122 display, which has now reached such a level of thoroughness that it will only deviate by a single day after 1,040 years. The 4-digit year display \u2014 a historic hallmark for the manufacture \u2014 remains in place as well.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.my-watchsite.fr\/blog\/wp-content\/uploads\/2026\/06\/iwc3-2.jpg\" alt=\"\" class=\"wp-image-49421\" \/><figcaption class=\"wp-element-caption\">The deep blue gradient dial is punctuated by white-printed numerals and hour markers, paired with rhodium-plated hands filled with luminescent material.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>A new generation of Perpetual Calendars<\/strong><\/h3>\n\n\n\n<p>The Big Pilot\u2019s Watch now highlights this innovation. It is available in steel, red gold, or a white ceramic &#8220;Le Petit Prince&#8221; edition, presented by Frank Sans C. The model is powered by the manufacture\u2019s self-winding calibre.

Forty years on, Vacheron Constantin proves that a perpetual calendar doesn\u2019t need a large case to remain perfectly legible. The day, date, month, leap-year cycle, and moon-phase indications preserve a well-balanced layout.

After all, ultra-thin watchmaking isn&#8217;t just about shaving off a few tenths of a millimetre. It strikes the perfect balance between slenderness, rigidity, and reliability. The perpetual calendar, which automatically accounts for varying month lengths and leap years until 2100, further upgrades this technical feat.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.my-watchsite.fr\/blog\/wp-content\/uploads\/2026\/06\/vc3.jpg\" alt=\"\" class=\"wp-image-49446\" \/><figcaption class=\"wp-element-caption\">This Traditionnelle Ultra-Thin Perpetual Calendar highlights a bezel and lugs set with 76 brilliant-cut diamonds.<\/figcaption><\/figure>\n\n\n\n<p>These three versions bring distinctive aesthetics: a pink gold edition with warm colourways, a white gold one enhanced by pink gold hands and hour markers, and a third reference set with diamonds.
