This Tag Heuer Carrera Calibre 1887 Chronograph replica model is dased on the bestselling Calibre 16 design but outfitted with the superlative Calibre 1887 movement and a host of other new technical elements – ceramic bezel with tachymetre scale, fine brushed and polished steel case and innovative H-shaped steel bracelet. The Arabic numerals – inspired by vintage counters–and the date window are hand applied.
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 Calibre 1887 is an integrated column-wheel Tag Heuer copy watch movement that vibrates 28,800 times per hour and has a 50-hour power reserve. Among it’s 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 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.
