The new Tag Heuer Carrera Calibre 1887 Chronograph Jack Heuer Edition watch combines the bullhead asymmetrical case design of the 2012 Mikrogirder with some of the distinctive design elements of the 80th Birthday Jack Heuer Carrera. The result is a spectacular watch clearly inspired by the two-part construction Heuer stop watches that were once used on pro racing circuits around the world.
Jack Heuer’s coat of arms and signature decorate the smoked sapphire caseback, through which can be seen the audacious 39-jewel Calibre 1887 movement, 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 case diameter is 45 mm. Water resistant to 100 metres.
