The **Reverso Tourbillon** was a limited-edition luxury watch by [[Jaeger-LeCoultre]] introduced in [[1993]]. It was one of the first complicated models in the [[Jaeger-LeCoultre Reverso|Reverso]] range and one of the first series-produced [[tourbillon]] watches.

===== Introduction =====
In [[1991]], Jaeger-LeCoultre re-established itself as a high-end watchmaker, adding a [[complication]] to the iconic [[Jaeger-LeCoultre Reverso|Reverso]] range as a signature piece. The resulting [[Jaeger-LeCoultre Reverso 60eme|Reverso 60eme]] showed what could be done in the tiny reversible Reverso case, adding a [[power reserve indicator]] and [[date by pointer]] to a larger "[[Jaeger-LeCoultre Reverso Grande Taille|Grande Taille]]" case with a [[display caseback]]. These elements were taken to a new level two years later with the Reverso Tourbillon.

The dial of the [[1993]] Reverso Tourbillon is remarkably understated, looking nearly identical to simple time-only Reverso Grande Taille models. Arabic numerals mark the hours, with the "JL" logo at 12 00 and a round [[small seconds]] dial at 6 00. Blued steel hands contrast with a rectangular [[guilloche]] dial surrounded by a [[chapter ring]] with tiny marks for minutes. Only the "Tourbillon" legend above the seconds subdial reveals the secret of this watch.

The case flips over to reveal Jaeger-LeCoultre's [[JLC 828|Cal. 828]], custom designed just for this application. A rectangular movement, Cal. 828 features a central [[tourbillon]] anchored to an open [[bridge]]. The rest of the movement is concealed under engraved gold [[plate]]s, apart from the center wheel. The upper area of the movement is dominated by a [[power reserve indicator|power reserve pointer]] showing 40 hours of power reserve.

The "Grande Taille" ("Large Size") case measures 42 mm tall by 26 mm wide like the 60eme, much bigger than the classic 38 mm by 23 mm Reverso or the square 24 x 23 mm [[Jaeger-LeCoultre Reverso II|Reverso II]]. It was a limited edition of 500 pieces.

This was the first real [[haute horology]] piece from the modern [[Jaeger-LeCoultre]], linking it to the [[Jaeger-LeCoultre Hybris Mechanica|Hybris Mechanica]] line thanks to its custom [[complicated]] movement. It was also one of the first series-produced tourbillon watches. Jaeger-LeCoultre's next innovation followed in [[1994]], the [[Jaeger-LeCoultre Reverso Répétition Minutes|Reverso Répétition Minutes]]. Ten years later, Jaeger-LeCoultre would produce a new Reverso Tourbillon, the [[Jaeger-LeCoultre Reverso Platinum Number One|Reverso Platinum Number One]].
