Tourbillon-Power Reserve

Any watch enthusiast dreams to get in his collection a tourbillon watch - a fascinating watch fabricated by precision work and high production technology.

The first tourbillon was developed in 1795, by the French-Swiss watchmaker Abraham-Louis Breguet. It was his aim to counter the effects of gravity by mounting the escapement and balance wheel in a rotating cage and thus, to negate the effect of gravity when the timepiece (and the escapement) is stuck in a certain position.

In the past, it has taken the watchmakers many months of manual working to fabricate those first tourbillons because they used to make every small part by hand. Nowadays, this work is done by CNC machines. Nevertheless, the assembling of these high-precision watches means a challenge for the master watch makers.
