Another reason why the Antoine Martin tourbillon is difficult to miss is the fact that Martin Braun has positioned it so prominently under the glass. Between the tourbillon (which also serves as a small seconds) and the glass, there is just enough space to accommodate a slim minute hand. This necessitated a number of design modifications, and the end result is a regulator-like display. Minutes are shown by the large central hand, while the hour display is found in a self contained subdial.
