Omega on Wednesday introduced the De Ville Tourbillon Numbered Edition, the luxury watch brand’s first timepiece with a Master Chronometer certified manual-winding central tourbillon.

Master Chronometer certification is a testing regimen for chronometers exclusive to Omega that was introduced in 2015. It goes beyond the CSOC chronometer certification that is standard in the Swiss watch industry. In fact, a watch first has to receive CSOC certification before being tested as a Master Chronometer. A watch must go through eight tests in 10 days to ensure superior precision and magnetic resistance before being certified as a Master Chronometer. The tests are overseen by the Swiss Federal Institute of Metrology (METAS), which has a lab at Omega’s headquarters in Biel/Bienne.

The tourbillon cage for this new timepiece is able to keep rotating under a magnetic field of 15,000 gauss, which is far more antimagnetic protection than you will likely ever encounter. Omega watchmakers set the tourbillon’s speed to one revolution per minute allowing the display of seconds, which is essential for achieving METAS certification. Omega in a statement described the two innovations as “extraordinary feats in tourbillon creation.”

The tourbillon is the focal point of the watch technically and literally as it sits in the center of the sun-brushed dial in PVD-treated 18k Sedna gold, which produces a darkened finish. Sedna gold is a rose gold alloy exclusive to Omega. The tourbillon cage is finished with hand polished bevels in black “ceramized titanium” — titanium with a ceramic coating.
