Experience Unrivaled Precision and Grandeur: The Duometre Heliotourbillon Perpetual in Platinum.

The Grand Return: A Modern Interpretation of a Masterpiece

Following a series of intricate timepieces showcased at Watches & Wonders 2026, including the Master Hybris Inventiva Gyrotourbillon and the Master Hybris Mechanica Ultra Thin, Jaeger-LeCoultre revisits its distinguished Duometre Heliotourbillon Perpetual. This renewed edition merges the brand's distinctive Duometre principle with a revolutionary triple-axis tourbillon and a comprehensive perpetual calendar, further enhanced by a large date display and a precise moon phase indicator, all presented in an opulent platinum construction.

Gravity-Defying Innovation: The Heliotourbillon's Complex Dance

Jaeger-LeCoultre's enduring legacy in crafting tourbillons reaches new heights with the triple-axis Heliotourbillon. This remarkable regulator defies gravity by rotating on three distinct axes. Constructed from lightweight titanium, two of its cages complete a rotation every 30 seconds, while the third revolves once every minute. Supported by ceramic ball bearings to minimize friction, this intricate mechanism comprises 163 components and weighs under 0.7 grams, showcasing unparalleled engineering.

Dual Power Systems: The Ingenious Duometre Mechanism

At the core of this timepiece lies Jaeger-LeCoultre's patented 2007 Duometre technology. This innovative system features two independent barrels and gear trains, seamlessly connected to a single regulating organ. One gear train diligently powers the time and calendar functions, ensuring consistent energy flow, while the other is dedicated to driving the complex tourbillon regulator, guaranteeing optimal performance and precision.

Unwavering Accuracy: The Integrated Perpetual Calendar

Addressing both precision and power supply, the manual-winding Calibre 388 integrates a sophisticated perpetual calendar. This mechanism automatically adjusts for varying month lengths and leap years, requiring no manual correction until the year 2100. Furthermore, it boasts the ability to be set both forwards and backwards without disrupting the calendar's synchronization, and includes a Grand Date display alongside a moon phase indication that maintains accuracy for the next 122 years.

A Glimpse into Artistry: The Meticulously Crafted Case

The impressive 44mm platinum case, standing at 14.7mm in height, draws inspiration from Jaeger-LeCoultre's 19th-century savonette pocket watches, offering a contemporary reinterpretation. Comprising 40 individual components, its elegant curves are adorned with a harmonious blend of polished, brushed, and micro-blasted finishes. The lugs, featuring recessed interiors, are securely fastened with screws, emphasizing the watch's robust yet refined construction.

Visual Spectacle: The Tourbillon's Unveiling

To highlight the mesmerizing spinning motion of the triple-axis tourbillon and its distinctive cylindrical hairspring, the watch's case incorporates a sapphire crystal window on its left side and a thoughtfully designed cut-out area on the dial, extending from 7 to 11 o'clock. Adjacent to the tourbillon, a deep blue lacquered starry sky backdrop features a 20-second track, subtly indicated by three red arrow pointers on the cage, creating a celestial display. A gracefully curved platinum bridge separates the dial from the regulator, unveiling this horological marvel as if drawing back stage curtains.

Harmonious Design: The Dial's Informative Layout

The pristine grey surface of the dial masterfully conveys all calendar information with remarkable conciseness, balance, and sophistication. Employing varied finishes to accentuate each indication, the dial adopts a rounded triangular form. Its apex is marked by the prominent big date window at 3 o'clock, elegantly integrated into the larger sub-dial for hours and minutes. The base of this triangle is defined by the day of the week and moon phase sub-dial at one end, and the month and year indications at the other. Additionally, two power reserve indicators are strategically positioned above and below the time display. A unique feature, patented by Jaeger-LeCoultre, highlights the final digit of the leap year in red, adding a touch of distinctive detail.

Precision Engineering and Elegant Wearability: Calibre 388 and Platinum Bracelet

The exhibition caseback provides an unobstructed view of the manual-winding Calibre 388, revealing its dual barrels and the exquisite radiating Geneva stripes adorning its bridges. A newly designed, flexible five-row platinum bracelet imparts a subtle hint of athleticism and enhances the watch's suitability for everyday wear. This exceptional timepiece is available in a limited edition of just 20 pieces, with pricing available upon inquiry.
