About the Defy Zero G family

The Defy Zero G was introduced in 2018 with a smaller version of Zenith's Gravity Control module, a gyroscopic cage that keeps the regulating organ horizontal whatever the position of the watch.

The catalog lists references in titanium, rose gold and yellow gold, and sapphire versions were made later. Dealers check that the module moves freely, the edition details and the papers.
