Speake-Marin One&Two Openworked Tourbillon – 42mm

After the successes of the “One&Two” Openworked Hours& Minutes and the “One&Two” Openworked Dual Time launched in the last two years, which marked a new aesthetic trend for the brand, Speake-Marin now extends its Openworked collection with a new complication: a 60 seconds Flying Tourbillon.

The new SMA05 Calibre is part of the SMA proprietary movement family and follows the “Openworked collection” approach with a strong element at 1:30: the flying tourbillon. By displaying a Tourbillon cage at 1:30, the Speake-Marin objective to break-away from the watchmaking codes is achieved: Speake-Marin is the only watchmaker who positions its tourbillon there. 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 red gold as a reminder of the Speake-Marin logotype. 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 flying tourbillon. For this new movement, Speake-Marin chose to develop a 3HZ movement (21,600 alt/h) so as to easily see the movement alternations on the tourbillon.
