The company claims that it is the most complicated mechanical pocket watch ever created, followed up by Patek Philippe Calibre 89 assembled in 1989 and featuring 33 complications.[3] The Reference 57260 took eight years to assemble.[4][5][6] The watch has 2,826 parts and 31 hands, weighs 957 grams and spans 98 mm.       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4The Reference 57260 is one of Vacheron Constantin’s tailor-made pocket watches with grand complications.[7][8] Members of the lineage include James W. Packard’s minute repeating pocket watch (1918), which was auctioned for US$1.763 million by Christie’s in New York on 15 June 2011, and King Fuad I’s pocket watch No. 402833 (1929), which ranks as one of the most expensive watches ever sold at auction, fetching US$2.77 million (3,306,250 CHF) in Geneva on April 03, 2005.[9][10] In addition, in 1946 Vacheron Constantin made a customized pocket watch for King Farouk of Egypt, the successor of King Fuad I, and in 1948 the company tailored another pocket watch for Count Guy de Boisrouvray of France.[11][12]The price agreed between the company and the client is confidential and has not been officially disclosed; however, various sources estimate the price to be in excess of $US10 million. It was built for a single customer, whose details are kept confidential and is only described as “A major watch collector”.[13]Table of Contents       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Technical specifications[edit]Fifty-seven complications by function[edit]Time measurement (6 functions)[edit]Perpetual calendar (7 functions)[edit]Hebrew calendar (8 functions)[edit]Astrological calendar (9 functions)[edit]Lunar calendar (1 function)[edit]Religious calendar (1 function)[edit]3-column wheel chronograph (4 functions)[edit]Alarm (7 functions)[edit]Westminster carillon striking (8 functions)[edit]Others (6 functions)[edit]Other complicated pocket watches[edit]References[edit]External links[edit]Technical specifications[edit]Reference: 57260\/000G-B046[14]Material: White goldDiameter: 98 mmThickness: 50.55 mmCaliber: 3750Diameter: 72 mmThickness: 36 mmNumber of components: Over 2,800Number of jewels: 242Frequency: 2.5Hz \/ 18,000 vibrations per hourPower reserve: 60 hoursNumber of complications: 57Fifty-seven complications by function[edit]Time measurement (6 functions)[edit]Hours, minutes, seconds, average solar time (regulator)Three-shaft tourbillonTourbillon regulator with spherical balance spring12-hour time zone, second hours and minutes time zone24-city display for each time zoneDay\/night indication for 12-hour time zonePerpetual calendar (7 functions)[edit]Gregorian perpetual calendarGregorian day nameGregorian month nameGregorian retrograde dateLeap year and four-year cycle displayNumber of the day of the week (ISO 8601 calendar)Week to view (ISO 8601 calendar)Hebrew calendar (8 functions)[edit]Hebrew perpetual calendar and 19-year cycleHebrew day numberHebrew month nameHebrew dateHebrew secular calendarHebrew century, decade and yearAge of Hebrew year (12 or 13 months)Golden number (19 years)Astrological calendar (9 functions)[edit]Seasons, equinoxes, solstices and signs of the Zodiac indicated by the hand on the sunStar chart (for the owner’s city)Sidereal time hoursSidereal time minutesEquation of timeSunrise times (for the owner’s city)Sunset times (for the owner’s city)Length of day (for the owner’s city)Length of night (for the owner’s city)Lunar calendar (1 function)[edit]Moon phases and age (one correction every 1,027 years)Religious calendar (1 function)[edit]Date of Yom Kippur3-column wheel chronograph (4 functions)[edit]Retrograde seconds chronograph (one column wheel)Retrograde split-seconds chronograph (one column wheel)Hours counter (one column wheel)Minutes counterAlarm (7 functions)[edit]Alarm with its own gong and gradual strikingAlarm strike \/ silence indicatorChoice of normal alarm or carillon striking alarm indicatorAlarm mechanism coupled to the carillon striking mechanismAlarm striking with choice of Grande or Petite SonnerieAlarm power-reserve indicationSystem to disengage the striking mechanism when alarm barrel fully unwoundWestminster carillon striking (8 functions)[edit]Westminster carillon chiming with 5 gongs and 5 hammersGrande Sonnerie passing strikePetite Sonnerie passing strikeMinute repeatingNight silence feature (10 p.m. to 8 a.m.)System to disengage the striking barrel when fully woundIndication for Grande or Petite Sonnerie modesIndication for silence \/ striking \/ night modesOthers (6 functions)[edit]Movement power reserve indicatorPower-reserve indication for the striking trainWinding crown position indicatorDual barrel winding systemTime setting in two positions and two directionsSecret mechanism (opening of the button for alarm arbor)Other complicated pocket watches[edit]References[edit]^ Pulvirent, Stephen (September 17, 2015). “Vacheron Constantin Unveils the Most Complicated Watch Ever Made”. bloomberg.com.
