Patek Philippe Reference No. 6105G-001 Celestial Sunrise and Sunset

Patek Philippe Reference No. 6105G-001, Celestial Sunrise and Sunset – A Starry Night on Your Wrist

 
Patek Philippe's First Complicated high quality replica watches Displaying Sunrise and Sunset Times
As a distinguished successor to Patek Philippe's astronomical timepieces, Ref. 6105G-001 offers a fresh perspective on the Celestial Ref. 6102. It is Patek Philippe's first watch capable of displaying Geneva sunrise and sunset times. Its movement features a sophisticated patented system that simultaneously corrects the time and sunrise/sunset times during daylight saving time and standard time transitions. The movement also incorporates a precise patented system that allows for easy and quick time correction, including simultaneous correction of sunrise and sunset times during daylight saving time and standard time transitions. Ref. 6105G-001, developed over five years and patented with six patents, is sure to captivate astronomy and watchmaking enthusiasts with its groundbreaking mechanics and striking modern design.
The Great Tradition of the Mechanical Universe
The connection between time measurement and astronomy has a long history. The stars have always fascinated watchmakers, inspiring them to measure time, mechanically reproduce it, and awaken their inner dreams. At Patek Philippe, creating complicated watches with astronomical displays is a long-standing tradition. Among the many masterpieces that have established its reputation, Patek Philippe has recently demonstrated its exceptional skill in this field again, launching a series of watches that incorporate celestial and moon phase displays to show the orbits of celestial bodies and our natural satellite—the Moon.
Therefore, the celestial moon phase display appears among the 21 additional indicators and functions of the Caliber 2000 pocket watch. This super-complication watch was launched in 2000 to welcome the new millennium. In 2001, the astronomical module from the Caliber 2000 was miniaturized and placed on the case back of the iconic Celestial Moon Tourbillon watch. This tourbillon watch boasts 12 complications, making it a breathtaking high-complication that encapsulates all the mysteries of the universe within a single timepiece. Finally, since 2002, with the introduction of astronomical replica swiss watches, the magnificent view of the starry sky has become the focus of the watch case back, powered by the 240 series ultra-thin automatic movement equipped with a micro-rotor.
Among the many astronomical watches created by Patek Philippe, only a very few models feature sunrise and sunset time displays. This rare function is mainly used in unique or limited-edition timepieces. For example, the legendary ultra-complication pocket watches created in 1927 and 1933 at the request of James Ward Packard and Henry Graves II, respectively. In recent years, this function has also appeared in the legendary Calibre 89 movement, Patek Philippe's most complicated timepiece to date (with 33 complications), released in 1989 to commemorate the brand's 150th anniversary. Furthermore, the renowned Star Caliber 2000 movement also features this function, launched in 2000 to welcome the new millennium.
To coincide with Watches & Wonders 2026, Patek Philippe is introducing this complication to a wristwatch for the first time, launching the new Ref. 6105G-001. This complex timepiece, equipped with a celestial display, is the culmination of over five years of development and six patent applications. This new interpretation of the "celestial display" adds the display of Geneva sunrise and sunset times to the existing complication. The ingenious mechanism driving this display automatically adjusts the time when daylight saving time and standard time change (standard time reflects the sun's natural cycle—the basis of civil time—while daylight saving time is artificially advanced by one hour).

A Paradise on the Wrist
Patek Philippe presents the new Celestial Reference 6105G-001, paying homage to astronomical watches in a poetic, precise, and modern way.
This newly reinterpreted Patek Philippe Celestial Watch retains its classic design, presenting a dynamic star chart in real-time of the night sky over Geneva or other cities at the same latitude (46°12′N) in the Northern Hemisphere, showcasing the apparent motion of stars, the angular motion of the moon, and the phases of the moon. The hands on the outer edge of the dial indicate the date, further enhancing the overall display. To further push the boundaries of haute horlogerie, Patek Philippe has incorporated a real-time display of Geneva's sunrise and sunset times into this celestial spectacle, and this display is constantly changing.
To breathe life into this breathtaking celestial movement, Patek Philippe has conceived an ingenious display system based on the delicate interaction of three superimposed transparent discs (made of sapphire crystal or mineral crystal). These three discs rotate at different speeds according to carefully calculated proportions. For the celestial dome, its rotation period corresponds to a sidereal day; that is, the average time interval between two consecutive transits of a star (such as Sirius) through the meridian of a specific location is slightly more than 23 hours, 56 minutes, and 4 seconds (with an exact value of 4.09892 seconds). A lunar day, the time interval between two consecutive transits of the moon through a specific meridian, has an average period of 24 hours, 50 minutes, and 28.328 seconds. A lunar month (the time between two full moons) lasts an average of 29 days, 12 hours, 44 minutes, and 2.82 seconds.
The date disc on the outer edge of the dial completes this astronomical mechanism. The numbers on the date disc not only display the date but also indicate sunrise and sunset times. Therefore, the number "1" in the date indicator is not aligned with noon as is usually the case. Engineers conceived and implemented a symmetrical layout of the information displayed on both sides of the dial to ensure that the two scales showing sunrise and sunset times appear balanced and harmonious to the reader.
Two skeletonized baton hands, made of 18K white gold and coated with white lacquer, indicate the hours and minutes of mean solar time (i.e., civilian time). A red hammer-shaped hand indicates the date, with a 31-day scale, printed on the outer edge of the dial using a transfer method. In addition, two white-lacquered baton hands indicate sunrise and sunset times respectively: the right hand indicates sunrise, and the left hand indicates sunset. This ingenious design allows the 1-31 markings on the date disc to simultaneously display the date and sunrise/sunset times. HYT S1 Titanium DLC Millésime Edition
Celestial Phases
The celestial dome is made of transparent sapphire crystal. Its upper surface is decorated with stars, forming a star map; the lower surface features a transfer-printed Milky Way, creating a magnificent sense of depth. As mentioned earlier, the dome completes one rotation in 23 hours and 56 minutes, matching the length of a sidereal day, and is driven by laser-cut gears along the edge of the sapphire crystal.
An oval pattern printed on the inside of the watch's sapphire crystal indicates the areas of the sky visible from Geneva (or any city at the same latitude in the Northern Hemisphere). When a star printed on the celestial disk enters this ellipse, it appears in the Geneva night sky.
Below the celestial disk, another disk made of mineral crystal rotates. For lightness and precision, it is mounted on an aluminum wheel. The disc's surface is coated black using physical vapor deposition (PVD), creating a deep, night-sky atmosphere. Its 24-hour, 50-minute rotation cycle simulates the moon's rotation as we observe it. A circular hole in this mineral crystal allows a view of a third disc, also made of mineral crystal. This disc is driven by planetary gears, and its rotation indicates the lunar phase. This extremely precise lunar phase display mechanism only requires one day of adjustment every 3000 years.
Sunrise and Sunset Time Indication
The new Celestial 6105G-001 is the first watch in Patek Philippe's current collection to display sunrise and sunset times. Furthermore, it employs an innovative patented system that automatically corrects for daylight saving time or standard time without affecting other astronomical displays.
Sunrise and sunset times vary seasonally, depending on the tilt of the Earth's axis of rotation relative to its orbital plane around the sun. This annual cycle is reproduced by a mechanical device with two oval cams, the geometry of which reflects the seasonal changes in the Earth's axial tilt. A patented dual-stylus mechanism reads the position of two cams via two flexible arms that always follow the cam profile. The two flexible arms of this component are always positioned on the cams and secured by a flexible guiding system. Their movement is linear, driven by two racks guided by a structure with two pairs of four-spring arms, thus accurately reproducing the movement of the stylus mechanism. The stylus mechanism's extremely small size (0.48 mm) allows for highly precise motion reproduction. Finally, the gear train transmits the information from this highly complex mechanism to the hands indicating sunrise and sunset times.
The two cams for sunrise and sunset rotate once per year. Driven by a rotating shaft, they move slowly and incorporate a mechanism with a patented eccentric finger, achieving optimized gear transmission within a confined space.
A patented daylight saving time and standard time conversion synchronization correction system
As a watch displaying sunrise and sunset times, Ref. 6105G-001 features a convenient mechanism that allows the wearer to easily and intuitively switch between daylight saving time and standard time without worrying about damaging the movement. Traditionally, these watches are set to civilian solar time, i.e., standard winter time. Therefore, when switching to daylight saving time, the sunrise and sunset times displayed on these watches will differ from standard winter time by one hour.
Therefore, the 6105G-001 model is Patek Philippe's first watch that can directly display sunrise and sunset times year-round. Twice a year, during the transition between daylight saving time and standard winter time (depending on the country), the wearer can simultaneously adjust the civilian time and sunrise/sunset times.
There are adjustment buttons at the 9 o'clock and 10 o'clock positions on the side of the case for switching between daylight saving time and standard winter time. Pressing the adjustment button at 9 o'clock advances the time by one hour to daylight saving time; pressing the adjustment button at 10 o'clock advances the time by one hour to standard winter time. The sunrise and sunset times will also be adjusted accordingly. A safety system prevents the user from pressing the same adjustment button multiple times. Therefore, switching between daylight saving time and standard winter time is very simple and convenient. replica tudor watches
Therefore, users can easily manage time changes related to daylight saving time or standard time. Technically, pressing one of the adjustment buttons triggers three actions: the hour star hand advances or retreats one hour to adjust the hour display; the date disc rotates forward or backward 1/31 of a turn, equivalent to one hour; the date star hand also rotates forward or backward 1/31 of a turn to synchronize with the date disc; and the sunrise and sunset hands remain in their positions. Thus, it is the rotation of the date disc (which also serves as the sunrise and sunset time scale) that allows the display to so cleverly adapt to daylight saving time and standard time!
The new 240 C LU CL LCSO
The new sunrise and sunset display mechanism and its ingenious adjustment mechanism (for daylight saving time and standard time) presented a challenge to watchmakers. Their task especially required keeping the new movement compact and minimizing the increase in thickness. The task was successfully completed: the 240 C LU CL LCSO movement has the same diameter as the Celestial movement, 38 mm. Despite the addition of 121 parts (out of a total of 426), the new movement is only 1.12 mm thicker, reaching 7.93 mm.
This movement boasts a power reserve of 38 to 48 hours, and its automatic winding function employs an elegant solution: an off-center 22K gold mini-rotor, a signature feature of the 240 series movements. Although the mini-rotor is small, the high density of 22K gold gives it sufficient mass and strength to ensure optimal winding of the mainspring barrel. This also allows this complex movement to remain remarkably thin and cleverly housed within an equally slim and elegant case.
As a derivative of the iconic ultra-thin 240 movement, the new self-winding 240 C LU CL LCSO movement features a Spiromax® hairspring made of Silinvar® and a Gyromax® adjustable balance wheel with a frequency of 21,600 vibrations per hour. This exquisite micromechanical watchmaking meets all the stringent standards of the Patek Philippe Seal, including superb craftsmanship and precise timekeeping, the latter further improved in 2024 to a daily error of no more than -1/+2 degrees.
The 47mm case boasts a striking, modern design.
To house this extraordinary movement, Patek Philippe opted for a white gold case. Measuring 47mm in diameter and 12.39mm thick, the case stands out with its bold, modern design. Its distinctive X-shaped pattern evokes the tubular structure of a space capsule. This pattern is presented directly in relief on the sides of the case, the contrast between polished and satin-brushed finishes creating a striking three-dimensional effect. Unlike most modern Patek Philippe mechanical watches, this decoration extends to the solid gold case back, adorned with a Calatrava cross.
This timepiece features two crowns. The first crown, located at 4 o'clock and decorated with the Calatrava cross, is used for winding and setting the time. The second crown, located at 2 o'clock, as indicated by its star-studded decoration, is used to set astronomical indicators: annual rings, sunrise and sunset times, star chart, lunar angle, and moon phase. It features a patented bayonet-style disconnect mechanism to prevent accidental operation: the user must press down on the crown and then rotate it to activate the setting function. Releasing the crown and rotating it counter-clockwise sets the sunrise and sunset times. This activates a hand to synchronize daylight saving time and standard time according to the annual cycle. Pulling the crown out to its second position and rotating it clockwise sets the moon phase, while rotating it counter-clockwise sets the star chart. Finally, the date can be corrected by repeatedly pressing the button between 7 and 8 o'clock on the side of the case. https://www.chronowrist.ru
To further demonstrate the meticulous attention to detail, a patented crown centering system ensures the crown is optimally positioned within the case's side height range. This not only maintains the harmonious unity of the case lines but also ensures a perfect integration of the crown with the X-shaped design.
A black, ultra-durable composite strap completes the watch's elegant look. It connects directly to the case via an invisible connection system, eliminating the need for traditional lugs. The strap naturally conforms to the shape of the wrist, providing stunning wearing comfort for this size timepiece. The openworked X-shaped pattern on the strap echoes the decoration on the side of the case, adding to the watch's modern and dynamic charm. Finally, the 18K white gold triple-folding clasp ensures both comfort and security when worn.
