FrontRunners: Split Personality

<< Back to Robb Report, Private Preview

The movement of the new Lange Double Split from A. Lange & Söhne (310.317.9852, is so stunning that it is tempting to wear the watch with the transparent caseback facing up. A true delight for a mechanical-watch purist, this piece is one of the most technically advanced rattrapante chronographs (a watch capable of recording intermediate—or split—times, such as those for different legs of a race). Most rattrapante models can record split times of 60 seconds or less. The Double Split ($97,800), however, can track split times of as long as 30 minutes because of the additional split hands on the minute subdial. Lange also has developed a disengagement mechanism to prevent the loss of efficiency that plagues most rattrapante chronographs when the split hand is stopped.


While aficionados will be fascinated by the movement’s technical artistry, they will find playing with the three pushers and seven hands hard to resist, ensuring that this piece will be worn right side up.
