800 CHF

1 in stock

The Calibre 1887 is TAG Heuer’s first movement built “in-house”, based on the Seiko TC78 chronograph movement. TAG Heuer acquired the rights to the European production of the TC78 from Seiko Instruments and then began the process of re-engineering and putting together the resources and skills to produce this high-precision “in-house” watch movement.

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.

The Calibre 1887 is made of 320 components, and it’s equipped with a High Efficiency Rewinding (HER) system, acknowledged by watch experts as the world’s most efficient rewinding system because of its bidirectional automatic system, which delivers 30% more efficiency than the traditional inverter system used in most Swiss chronographs. The HER is also famous for its superior reliability and sturdiness.
