Fresh to the market, the present watch is an outstandingly rare and attractive variation of what can arguably be considered the most sophisticated chronograph wristwatch ever designed: the Lange double split. The hefty platinum case - now discontinued - is furthermore lavishly fitted with 48 baguette-cut Top Wesselton VVS diamonds for a total of 5.2 carats. The icy beauty of the white metal and the brilliance of the diamonds create a perfect contrast with the black dial, for a breathtaking aesthetic effect. The technical side of this piece is no less momentous than its aesthetic impact.

When the Double Split was presented to the public in 2004, it was hailed with unbridled acclaim by industry experts, serious collectors, and simple enthusiasts alike. Hardly ever has a new model been so positively received, and such a response was indisputably more than deserved.

Split seconds chronographs are used to time two events happening simultaneously - such as two cars racing in a circuit - and are extremely deceptive in their complexity. One might legitimately ask him/herself: is it so difficult to put two chronograph hands one on top of the other? The answer, simply and beyond any argument, is yes! As a matter of fact, the split second complication (or "rattrappante") is one of the most daunting complications in watchmaking, comparable to the minute repeater. The mechanical complexity of having the second hand re-set properly and precisely on top of the running first one when released presents enormous technical challenges. In the case of the Double Split, however, Lange pushed the boundaries of portable watchmaking even further, and added a split minute counter as well. This overcomes one of the great limitations of the "classic" rattrappante: the fact that the two events being timed could not have a difference in length superior to one minute. The Double Split allows to record separate times with a difference of up to 30 minutes instead.

The inspiration for this movement comes from an historical Lange watch, a pocket timepiece dating to the end of the 19th century; of course the research and development involved in adapting the complication to a wrist piece are more than remarkable. The result of such an effort is what is considered by many the ultimate chronograph movement, not only for its technical complexity, but also for the flawless finishing and sheer aesthetic beauty.
