A NEW MEASURE OF EXCELLENCE AND A NEW GENERATION OF HIGH-QUALITY MECHANICAL CHRONOGRAPH MOVEMENTS Vibrating 28,800 times per hour, the Calibre 1887’s 39-jewel, 29.3mm x 7.13mm movement is made of 320 components and has a 50-hour power reserve. A powerful, robust and easy to maintain engine, it houses an audaciously re-engineered version of its inspiration, the brand’s 1887-patented oscillating pinion, along with a matching column wheel. The oscillating pinion, patented in 1887 by Edouard Heuer, works in tandem with the column wheel, in much the same way as an automobile transmission. The column wheel, which coordinates the start, stop and return-to-zero functions of the chronograph hand, functions like a gearbox. The smoothness and precision of its super-soft click start is a recognized element of high-end watchmaking excellence.
