The new Fifty Fathoms features a large date complication – a first for this contemporary line, launched in 2007. The date, in two windows at 6 o'Clock, is set by the crown and changes instantaneously at midnight without draining energy from the running train. There is also a unidirectional bezel. The in-house movement is powered by three series-coupled barrels which provide an impressive five days of power reserve. The non-magnetic silicon balance spring protects the movement from magnetic fields without the need for a soft iron inner case.
