Calibre 1887 MOVEMENT
The Calibre 1887 is an integrated column-wheel watch movement that vibrates 28,800 times per hour and has a 50-hour power reserve. Among its 320 components, is an audaciously re-engineered version of its inspiration, the brand’s 1887-patented oscillating pinion, along with a matching blue 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 oscillating pinion works like a clutch.
"The in-house movement that re-engineers one of Edouard Heuer’s greatest contributions to watchmaking: the oscillating pinion of 1887".
