Since 2015, Speake-Marin has initiated a movement strategy to fully develop and assemble proprietary movements within its atelier in the Neuchatel area, Switzerland. This new strategy gave birth to the “SMA” collection, which includes Openworked, closed dials and Haute Horlogerie movements. Firstly, Speake-Marin focused its efforts on Haute Horlogerie 3 Hz movements (Minute Repeater and Double Tourbillon). Then, Speake-Marin developed Hour Minutes Seconds 4Hz movements, which were featured in the new One&Two design as an Openworked movement named SMA01. This movement is particular due to the small second counter being positioned at 1:30 and its integrated micro-rotor.
