Speake-Marin puts a new spin on the One&Two Openworked

The One&Two Openworked introduced a new aesthetic at Speake-Marin. Two years after the launch, the brand is extending the line with a 60-seconds flying tourbillon.

The new SMA05 Calibre is part of the SMA proprietary movement family and follows the “Openworked collection” construction approach with a strong element at 1:30, the flying tourbillon. Speake-Marin’s objective is to break-away from the traditional watchmaking codes. It is actually a real constraint in terms of movement development since the tourbillon cage at 1:30 has to go through the time setting module. It is even more complicated than a small second at that place because the tourbillon cage requires more space in length and depth.

The tourbillon cage is covered by the iconic Speake-Marin rotor shape in black. The main plate has a microblasted black finish which brings depth to the dial. The regulating organ is especially accurate, with a precision of +/- 4 second per day, which is a very good performance for mechanical movements with a flying tourbillon. For this new movement, Speake-Marin chose to develop a 3Hz movement (21,600 alt/h) to easily see the movement alternations on the tourbillon. Last but not least, the SMA05 Calibre displays a power reserve indicator at 7:30 (72 hours). It creates a visual balance between the barrel, the oscillating mass, the tourbillon and the power reserve, while the sharp edges of the bridges are counterbalancing the classical shape of the case. This movement is nestled in a new version of the Piccadilly, allowing the straps to be integrated closer in the case. This limited edition is proposed in 10 pieces only.
