Jaeger-LeCoultre Reverso Tribute Minute Repeater: A New In-House Striking Movement
The Reverso Strikes Again with a New Calibre
Jaeger-LeCoultre has unveiled a spectacular Reverso Tribute Minute Repeater in 18k pink gold, powered by a newly developed fully integrated rectangular-shaped minute repeater movement. Limited to 30 pieces at USD 299,000, this watch represents the latest chapter in the Manufacture's 150-year legacy of striking mechanisms dating back to 1870.
Two Faces, One Movement
The front dial is decorated with a radiant hand-guilloché barleycorn pattern enhanced with Grand Feu enamel in a striking teal blue colour, executed in the brand's Métiers Rares atelier. The reverse dial offers a radically different view — an openworked display revealing the new rectangular calibre 953 movement with its hammers and gongs in full mechanical action.
Faceted gold indices on the reverse side are cantilevered from a blue lacquered railway minutes track, appearing to float above the movement. A bridge spanning the movement from 7 to 5 o'clock, supporting the hammers, is decorated with blue lacquer to match the front dial's teal tones.
Seven Patented Innovations
The new calibre 953 incorporates seven of Jaeger-LeCoultre's patented striking innovations:
- Crystal Gongs (patented 2005) — attached directly to the sapphire crystal for enhanced resonance
- Trébuchet Hammers (2009) — catapult mechanism that strikes gongs with less energy without reducing volume
- Silent-Interval Elimination — ensures seamless chime sequence
Despite the energy-intensive minute repeater complication, the movement offers an impressive 48-hour power reserve.

Engineering Excellence
The rectangular-shaped minute repeater is one of the most challenging complications to engineer. Jaeger-LeCoultre's original 1994 Reverso Minute Repeater was the first rectangular-shaped minute repeater in history. This new iteration builds on three decades of refinement, with the integrated calibre 953 representing the most advanced version to date.
The adjustable pink gold folding clasp features a double-wheel mechanism for micro-adjustments to the nearest 0.5mm — a small but significant detail for a watch that weighs approximately 30 grams on the strap.
Frequently Asked Questions
Q: How does a minute repeater work?
A: A minute repeater chimes the time on demand using hammers that strike tuned gongs. The sequence sounds the hours, quarter-hours, and minutes — allowing the wearer to hear the time in the dark.
Q: What is the crystal gong system?
A: Patented by Jaeger-LeCoultre in 2005, crystal gongs are attached directly to the sapphire crystal, which acts as a resonating chamber to amplify the chime's volume and clarity.
Q: How does the silent-interval elimination work?
A: This patented system eliminates the brief pause between the hour and minute strikes, creating a seamless chime sequence without the traditional silent interval.
