Lang & Heyne Calibre IX

Calibre IX is Lang & Heyne's in-house manual-wind flying tourbillon, introduced in 2018 as the manufacture's first tourbillon movement. Operating at 2.5 Hz with a 55-hour power reserve, it features steel cocks secured with blued screws and is paired with a Grand Feu enamel dial. The movement's angular architecture was designed specifically for the rectangular Anton case. It remains in production.
