Furthermore, the natural oscillation of the silicon 1.1.1 balance spring – which
beats at the high frequency of 28,800 vibrations per hour (4 Hertz) – is only
very slightly disturbed. In fact, the contact between the balance and the
escapement takes place over a 32° arc, whereas this lifting angle is 48° on a
Swiss lever escapement. The amount of disturbance is therefore reduced to
a minimum.
But these are not the only secrets of the incredible manual-wind caliber UN-205,
which generously reveals all through the sapphire case-back. Stripped of its
crown, the Freak Cruiser is adjusted in a phenomenal way. Located between
the lugs at 6 o'clock, a safety catch is used to liberate the rotating bezel. This
adjusts the hours and minutes when turned in either direction. As for winding
the barrel – designed to offer a power reserve of more than seven days – this
is done using the rear bezel mounted on ball bearings. These two bezels, front
and back, are an integral part of the movement.
So simple and user-friendly, the Freak Cruiser can be wound by turning the
lower bezel, and the time can be adjusted by turning the upper bezel; while
the direct gear link crafted between the three "hands" averts dephasing, or
the throwing of hours, minutes and seconds out of step when adjusting or
readjusting time.
Not only brilliant in function, the Freak Cruiser is also stunning in aesthetic
with its clean lines, robust black and charcoal tones and is the ultimate symbol
of unwavering imagination and unusual style, staying true to the inventive
character that defines the Freak timepiece collection.
