One&Two Openworked Tourbillon 38mm

Speake-Marin 2020

ref. 413811250
Women's

Following on from the One&Two Openworked watches introduced two years ago, Speake-Marin extends the collection with a new model, produced as a limited edition of five pieces each in two sizes (38mm or 42mm), in a titanium Piccadilly case. The eye is immediately drawn to the 60-second flying tourbillon at 1:30 – an unusual position for which the time-setting module had to be moved. One line of symmetry in the Calibre SMA05 movement is formed by the micro-rotor and the barrel, which has the name of the watch engraved on it. A second line of symmetry runs from the power-reserve indicator to the tourbillon regulator, timed at 21,600 vibrations/hour so each pulsation is more distinctly visible. Whether viewed from front or back, the movement architecture has been carefully orchestrated, as admirers of fine mechanisms will appreciate.
