Both presented at the Salon International de la Haute Horlogerie, the two timepieces protagonists of this article are not only united by the belonging to the category of chronographs , but also by the opportunity to admire their movement at work through the sapphire crystal case back . The first, signed A. Lange & Söhne , boasts the world’s first mechanical chronograph record with a split-seconds hand that can measure additional and comparative times up to twelve hours. This means that, for example, it allows you to measure the times of two opponents of a race (from Moto Gp to the Tour de France), those of events that start in succession, and add times of events that last several hours.
The second, proposed by Montblanc instead , pays homage to none other than the inventor of the category, namely Nicolas Rieussec , who in 1821 conceived the ink chronograph, the first patented in the world. Reinterpretation of a model proposed in 2008, strongly re-elaborates its appearance without forgetting its distinctive characteristics.
Triple Split / A.Lange & Söhne
With this limited edition of 100 copies, the Manufacture breaks the record so far held by another model of his, the Double Split. How does it work? With the chronograph stopped the central seconds hand, the minutes and hour counter are overlapped. As soon as the measurement starts, they start simultaneously, until they are separated by the button action. The three browned hands stop and detect the intermediate time, while the seconds, minutes and hour counters continue to advance and detect the total time. Pressing the rattrapante button a second time, the three hands stop the chronograph hands and shoot together to measure the time. Furthermore, by pressing the lower button, the chronograph can be reset and restarted immediately, even during a measurement in progress. The gray dial is coordinated with thecase in 18 carat white gold and the three hands of the rattrapante in burnished steel stand out from the rhodium-plated ones of the chronograph.
Montblanc / Star Legacy Nicolas Rieussec Chronograph
The reinterpretation of the monotonous chronograph Nicolas Rieussec, presents the distinctive off-white silver-plated dial completely reworked to ensure greater visibility and enhanced by an elegant guilloche processing. The MB R200 manufacturing caliber that animates it, and guarantees a 72-hour power reserve, can be admired through the sapphire crystal case back with its components decorated in Côtes de Genève with shiny bevelled edges, rubies and blued screws with golden finish. Reminiscent of Minerva’s pocket watches, it features a new 44.8 mm rounded case, curved finishes on the sides and side-to-side handles, as well as the characteristic onion crown decorated with the Montblanc emblem. It is waterproof up to 30 meters .
