A shield for Omega's Central Tourbillon

Omega unveils the new De Ville Tourbillon Numbered Edition, the first Master Chronometer certified manual-winding central Tourbillon Not only does this certification assure high standard of precision and performance, but it certifies that the tourbillon cage is able to keep rotating even under a magnetic field of 15,000 gauss At the centre of the dial is the tourbillon cage with hand polished bevels in black ceramised titanium.

Other historical highlights include the first-ever wristwatch Tourbillon calibre, which was created by Omega in 1947 and entered into the precision competitions at three major European Observatories Almost 50 years later, in 1994, Omega introduced the first self-winding Central Tourbillon wristwatch, with the Tourbillon carriage positioned in the middle of the watch A decade later, in 2004, Omega would produce the first Tourbillon wristwatch to be Chronometer certified.
