A new dimension in timekeepingSIHH 2018: The new TRIPLE SPLIT by A. Lange & Söhne

On 17 July 2016, German triathlete Jan Frodeno achieved a new world record for the triath-lon long distanceIn an amazing seven hours, 35 minutes and 39 seconds, he mastered the combination of swimming 3.8 kilometres, cycling 180 kilometres and running 42.2 kilometres.

It took 20 minutes and 44 seconds longer for the runner-up, Joe Skipper of Britain, to reach the finish line. Among all mechanical rattrapante chronographs, only one would have been able to precisely record the times of the winner and the second-placed competi-tor in hours, minutes and seconds: the new TRIPLE SPLIT by A. Lange & Söhne.

The only split-seconds chronograph in the world that can measure additive and compara-tive times for as long as twelve hours is in a league of its own. At the same time, it has bro-ken the house record of the DOUBLE SPLIT, which in 2004 allowed the first comparative measurements with an aggregate duration of 30 minutes and since then has defended its unique position. With a precisely jumping rattrapante minute counter and a continuous rattrapante hour counter, the TRIPLE SPLIT multiplies the measuring range of the rat-trapante function by a factor of 24. This covers many more diversified and interesting ap-plications: for instance, the TRIPLE SPLIT can compare the times of two opponents in a For-mula 1 race, a Tour de France leg or a marathon. It can also record the times of consecu-tively starting events, such as the outbound and return legs of a long-haul flight. Also, it is possible to add the times of multi-hour events, such as the duration of individual Ironman disciplines. Any number of lap times can be stopped during an additive time measurement.

In the passive mode, the respective hand pairs – sweep seconds, minute- and hour-counter hands – are superposed. As soon as the measurement is started, they all begin to run simul-taneously until the rattrapante pusher is pressed to freeze intermediate times. The three blued-steel hands stop to display lap times while the seconds hand as well as the minute- and hour-counter hands continue to run and measure the total time. A second actuation of the rattrapante pusher causes the three stopped hands to catch up and synchronise with the running hands that continue to measure the duration of the event.

Limited Edition of 100 timepieces

The TRIPLE SPLIT – which comes in a limited edition of 100 pieces – is endowed with a fly-back function that involves all three hand pairs as well. Thus, the chronograph can be reset and instantly restarted by pressing the lower chronograph pusher even during an ongoing measurement. A power-reserve indicator based on Lange's typical UP/DOWN display shows how much of the 55-hour reserve remains available. The well-organized grey dial in solid silver is colour-coordinated with the 18-carat white-gold case that has a diameter is 43.2 millimetres. The three rattrapante hands in blued steel clearly set themselves apart from the rhodiumed chronograph hands. The hands that display the time and the applied baton hour markers are made of rhodiumed gold. The hour and minute hands are luminous.

The TRIPLE SPLIT asserts Lange's ambition to enrich precision watchmaking with useful innovations. The development of a triple rattrapante mechanism that controls the three hand pairs collectively or separately confronted the engineers with enormous technical challenges. Even a simple rattrapante mechanism has two hands attached to arbors that run one inside the other. In the case of the triple rattrapante mechanism, this arrangement is three-fold: two seconds hands as well as two hands each for the minute and hour coun-ters. For the watchmaker, the multiple arbor configurations require the ultimate in dexteri-ty and extreme patience in adjusting the endshakes.

The design of the movement assures that neither the measurement of lap times nor the pro-gression of the precisely jumping minute counter has a negative effect on rate stability. The normally unavoidable loss of amplitude is prevented by a disengagement mechanism devel-oped and patented by A. Lange & Söhne. Without this device, friction losses would occur when the rattrapante function is activated. Because it rotates slowly and continuously, the hour counter does not need such a mechanism.

The manufacture calibre L132.1 is a newly developed movement that significantly distinguishes itself from the calibre L001.1 of the DOUBLE SPLIT. The power-reserve indicator has been shifted down to provide more display space for the rattrapante hour counter in the upper part of the dial. Despite the extended functionality, the engineers succeeded in integrating the additional components in the movement so ingeniously that the case did not have to be enlarged in comparison with the DOUBLE SPLIT. A glance through the sapphire-crystal caseback reveals the chronograph movement finished to the highest Lange standards as well as the painstakingly choreographed interaction of wheels, levers, springs, clutches and jumpers that illustrates the stunning complexity of the project.
