Thomas Prescher Single Axis Tourbillon
18k white gold Thomas Prescher Tourbillon featuring Thomas' own caliber in the square case. Uniquely designed by Thomas, the flying tourbillon has a constant force mechanism in the cage, to improve time keeping over the different amplitudes of the mainspring as it unwinds.
An unusual trigonal guilloché is found on the caliber back, together with the traditional hallmarks of a finely hand finished mechanical watch, anglage, black polish and a solid silver hand guilloché dial. This watch sports a sub dial for the seconds hand and the tourbillon appears right under the curved sapphire crystal.
