An amazing watch from the Manufacture.
One of only 75 made, so you're indeed fortunate to have the chance to see it in real life, Bruno! (ps - when are you getting yours?! ;))

Here's the Press Release from its introduction at SIHH in 2006:
-----------------------------------------------------------

Displaying three dimensions of time on three faces, the Reverso grande complication à triptyque is a world first and a unique expression of the Manufacture's total mastery of both traditional finewatchmaking tradition and avant-garde technology.

A few years ago Jaeger-LeCoultre set itself a challenge: to bring together civil, sidereal and perpetual time in the legendary reversible case. But the Reverso grande complication à triptyque's achievements go beyond this: its manually wound mechanical movement offers some unique subtleties of construction as well as extraordinary horological complications.

On its front face, it has a tourbillon endowed with an ellipse isometer escapement, a masterpiece of design and execution whose transmission system does away with the traditional Swiss pallet. Inspired by marine escapements, it offers peerless precision.

Its back face features a zodiacal calendar with an astronomical chart, an equation of time and sunrise and sunset times.

The watch's third face is remarkable for its unique location: a perpetual calendar in the Reverso carriage. A highly original patented mechanism makes it possible to transmit energy from the movement to the carriage. In total, the timepiece boasts 18 complications, and has six patents pending.

The Reverso grande complication à triptyque is an exceptional watch in every respect - creatively, aesthetically and technically. Only the Manufacture Jaeger-LeCoultre could have conceived of and delivered such a brilliant mechanism. A team of engineers, technicians, designers and watchmakers invested some three and a half years of intensive effort in the project before being able to present it to the world.

No fewer than six patents protect the various constituent mechanisms, from the tourbillon connected with the detached escapement to the ingenious lever movement that connects case and carriage. Excellence of this kind is always a rarity. As such, only 75 examples, housed in distinctive platinum cases, will be produced.

The watch retails for about $375,000 USD. For just a bit more, I'd look at some type of discreet Patek Phillipe like a YG or RG Tourbillon Minute Repeater.:)

Well, I think I have 5K left, so if you donate me about 300K ... it could happen pretty soon LOL

This could be sacrilegeous, but I've never been persuaded by the charms of a minute repeater. I mean, I grew out of watches that made sounds when I was 11 and my Casio digital chimed at midday (did that piss my teachers off! :)) and played a bunch of other tunes.

Or perhaps it's the small matter of the several hundred thousand $$ I don't have which makes me hard to persuade...;)

I agree with you completely, Harb. As I'm sure like you, I can appreciate the artistry and admire the work and dedication that goes into making a wonderful time piece, but I would not wear a minute repeater even if I could afford one. IMO those are collector's pieces, or designed for wealthy blind people.

Besides, I didn't see anything about water resistance. Is it at least pool-safe? ;)

I would like to know how they transfer energy from the movement to the calendar in the back there.... Very clever.
