The first barrel is fitted with a slip spring. When the user winds the movement, the two barrels charge simultaneously. As the main barrel discharges, the auxiliary barrel transmits its energy to it, recharging it, according to the principle of communicating vessels.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\"><strong>ISTANTANEOUS DAY AND DATE JUMPS<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For the instant-jump day and date mechanism, Patek Philippe returned to the principle introduced in the Cubitus Instantaneous Grand Date, Day and Moon Phases Reference 5822P-001, unveiled in October 2024 (self-winding caliber 240 PS CI J LU) \u2013with a 24-hour wheel comprising a cam fitted with a dual- function spring. This system makes it possible to overcome a higher torque, while guaranteeing precise jumps. Each night, at midnight, the large lever equipped with two beaks falls on the 24-hour cam, and in falling, engages direct with the day star and the date star. The two indications then jump simultaneously and instantaneously, thanks to the energy accumulated throughout the day.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_10.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"682\" height=\"1024\" src=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_10-682x1024.jpg\" alt=\"Patek Philippe Calatrava 8 Days Ref.5328G\" class=\"wp-image-25799\" srcset=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_10-682x1024.jpg 682w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_10-200x300.jpg 200w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_10-768x1152.jpg 768w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_10-1024x1536.jpg 1024w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_10-600x900.jpg 600w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_10.jpg 1181w\" sizes=\"auto, (max-width: 682px) 100vw, 682px\" \/><\/a><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_09.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"682\" height=\"1024\" src=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_09-682x1024.jpg\" alt=\"Patek Philippe Calatrava 8 Days Ref.5328G\" class=\"wp-image-25800\" srcset=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_09-682x1024.jpg 682w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_09-200x300.jpg 200w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_09-768x1152.jpg 768w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_09-1024x1536.jpg 1024w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_09-600x900.jpg 600w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_09.jpg 1181w\" sizes=\"auto, (max-width: 682px) 100vw, 682px\" \/><\/a><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The day display is performed by a disk that was lightened and pierced to reduce its weight and its inertia at the moment of the jump \u2013 and thereby avoid any undesirable double jump. The date is indicated by a hand positioned on a counter concentric with the small seconds at 6 o\u2019clock. Thanks to the beveled shape of the dual-function spring,\u00a0<strong>the new caliber makes it possible to set the time at any hour of the day or night, backwards or forwards, even during the passage of midnight, with no risk of damaging the movement<\/strong>. Furthermore, the caliber is equipped with a \u201cstop-seconds\u201d function enabling the time to be set to the nearest second. The date requires correction five times a year, on the first day of the months of March, May, June, October and December, using the corrector positioned on the caseband between 3 o\u2019clock and 4 o\u2019clock.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\"><strong>NEW DIAL AND EMBLEMMATIC CASE<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to its special functions and increased autonomy, the new Calatrava 8 Days stands out by its originality as regards the displays. The power reserve indication, transfer printed along an arc (is visible on a subdial at 12 o\u2019clock, while the day aperture, the date hand and the subsidiary seconds dial form a group at 6 o\u2019clock. This arrangement along a vertical axis, particularly legible, also endows the watch with a unique personality. The&nbsp;<strong>textured dial in blue with a black gradient rim<\/strong>&nbsp;presents syringe-style applied numerals and hour and minute hands, all in white gold, emphasized by a white luminescent coating.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_03.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_03-1024x682.jpg\" alt=\"Patek Philippe Calatrava 8 Days Ref.5328G\" class=\"wp-image-25803\" srcset=\"https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_03-1024x682.jpg 1024w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_03-300x200.jpg 300w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_03-768x512.jpg 768w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_03-1536x1024.jpg 1536w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_03-600x400.jpg 600w, https:\/\/www.watchinsanity.it\/wp-content\/uploads\/2025\/04\/Patek_Philippe_Calatrava_8Days_5328G_Watch_Insanity_03.jpg 1772w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The caseband of the&nbsp;<strong>41mm round case in white gold<\/strong>&nbsp;is decorated with&nbsp;<em>guilloch\u00e9&nbsp;<\/em>work in the&nbsp;<em>Clous de Paris&nbsp;<\/em>or hobnail pattern.
