Calibre 1887 is TAG Heuer replica watch‘s first home movement, which was released in December 2009. Based on Seiko 6s37 timing movement, TAG Heuer transformed it into a mechanical movement equipped with vibrating gear and integrated guide pillar wheel.

This automatic chain movement has 40 hours of power storage and can vibrate 28800 times per hour. The movement has a diameter of 29.3mm (13 French points), which is composed of 320 parts, a total of 39 bearing rubies, and the surface is decorated with Geneva ripple.

In 2010, TAG Heuer replica watches released the first watch equipped with calibre 1887 movement – Tag Heuer Calibre 1887 Replica Watches. The 9 o’clock, 12 o’clock and 6 o’clock positions of the dial are respectively equipped with second, minute and hour timing plates, in which the hour timing plate is also equipped with date display. Since then, the Carrera chronographs released by TAG Heuer replica watches are also equipped with calibre 1887 movement. This short film shows us the production process of this movement.
