Considering that Antoine LeCoultre – founder of the company – invented the first machine capable of measuring a micron, it's safe to say that Jaeger-LeCoultre have a deep connection with precision. Precise measurements may be important for all watchmaking, but there's a vast chasm of difference between even mid-range luxury and the levels of JLC's upper echelon. Watches and Wonders 2024 has seen the launch of Jaeger-LeCoultre's annual theme, and that's a thorough exploration of what precision means to the brand, and there’s no better person to explain this than CEO Catherine Renier, who took our own Andrew McUtchen on the journey.Duometre Heliotourbillon PerpetualThe Jaeger-LeCoultre Duometre Heliotourbillon Perpetual proves just how much the Duometre system can cope with.In addition to a perpetual calendar with a grand date display, the new calibre 388 movement boasts a heliotourbillon which rotates like a spinning top thanks to three cages.Each of the mainspring barrels provides 50 hours of power supply.BrandJaeger-LeCoultreModelDuometre Heliotourbillon PerpetualReference NumberQ6202420Case Dimensions44mm (D) x 14.7mm (T)Case Material18k Pink goldWater Resistance30 metersCrystal(s)SapphireDialSilver opalineStrapBrown alligator leatherMovementCalibre 388, in-house, manual windingPower Reserve46 hours per barrelFunctionsHours, minutes, seconds, heliotourbillon, perpetual calendar, moonphase, two power reservesAvailability20 piecesPrice484,000Duometre Chronograph MoonThe first Duometre in 2007 was a chronograph, so here the range's reinvention is most clear.Measuring sixths of a second is cool enough as is, but having the constantly-spinning foudroyante hand makes for an amazing party trick.In contrast to the speed of the 1/6th second chronograph, the new calibre 391 can also accurately track the slow phases of the moon.BrandJaeger-LeCoultreModelDuometre Chronograph MoonReference NumberQ622252JQ622656JCase Dimensions42.5mm (D) x 14.2mm (T)Case Material18k pink goldPlatinumWater Resistance50 metersCrystal(s)Sapphire front and backDialSilver opalineCopper opalineStrapAlligator leatherMovementCalibre 391, in-house, manual windingPower Reserve50 hours per barrelFunctionsHours, minutes, seconds, chronograph with 12-hour counter, 30-minute counter, 1/6th-second counter and central chronograph seconds, moonphase, night/day indicator, two power reserve indicatorsAvailabilityNowPriceA$119,000, 79,000 (pink gold)A$146,000, 97,000 (platinum)Duometre Quantieme LunaireJLC's Duometre technology provides two separate mainsprings and gear trains for the timekeeping and complications, heightening the possible accuracy and negating the stresses of power demand.A foudroyante hand careens on the dial, rotating once per second with 6 intervals to measure 6ths of a second.Its blue opaline dial provides a gentle glow, complimenting the moonphase display.BrandJaeger-LeCoultreModelDuometre Quantieme LunaireReference NumberQ604848JCase Dimensions42.5mm (D) x 13.05mm (T)Case MaterialStainless steelWater Resistance50 metersCrystal(s)Sapphire front and backDialBlue opalineStrapAlligator leatherMovementCalibre 381, in-house, manual-windingPower Reserve50 hours per barrelFunctionsHour, minutes, central seconds, 1/6th of a second, moonphase, date, two power reservesAvailabilityNowPriceA$71,500Jaeger-LeCoultre Master Ultra Thin Perpetual CalendarThe Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar collection has been given a gorgeous update with 18k pink gold and midnight blue.This new colour combination brings one of JLC's most highly-respected watches into a welcome realm of smart casual.The 39mm diameter and 9.3mm thick makes it one of the more compact perpetual calendar watches out there.BrandJaeger-LeCoultreModelMaster Ultra Thin Perpetual CalendarReference NumberQ114258JQ1142510Q1142501Case Dimensions39mm (D) x 9.3mm (T)Case Material18k pink goldWater Resistance50 metersCrystal(s)Sapphire front and backDialMidnight BlueEggshellStrapAlligator leatherMovementCalibre 868Power Reserve70 hoursFunctionsHours, minutes, seconds, perpetual calendar with red security zone, moon phasesAvailabilityNowPriceA$65,500
