FREESDIAL

The FREESDIAL name, which the watch bears, on the one hand describes that the watch has dials that are not fixed in place (FREE DIALS) and on the other hand that the hands and dials of this watch move in “FREESTYLE”. The special minute hand, which also changes in length, moves over the moving dials (FREE DIALS). On the back of the watch, 3 additional, freely rotating indicator discs (FREE DIALS) are integrated in the winding rotor. These 3 indicator discs are each installed centrally with a ball bearing and rotate freely around their respective axis of rotation. The hand and dials of the minute indication move in a specific “FREESTYLE” manner and fundamentally differ from other watches, which usually feature a fixed watch face and hands that continuously rotate from the centre of the watch. The NORD N4 movement contains 30 ruby jewels and 14 precision ball bearings.

MINUTE
INDICATION

The indication of the minutes is performed via the hand controlled by the eccentric cams, as well as by the 2 movable dials. (FREE DIALS) The entire hand assembly group is comprised of a total of 27 individual components. The hand is powered by 2 counter-rotating gear wheels with fitted eccentric cams. The hand changes its length over the course of the 60 minutes by means of the additional eccentric lever. The additional eccentric lever is connected via a connecting rod with the hand tip that shifts. As a result, the tip of the hand moves and slides up and down on the main hand, in which the tip of the hand achieves the greatest lift per minute at approx. 15 minutes and 45 minutes. In turn, the main hand reaches its greatest lift and highest speed per minute in the area of 60 minutes and 30 minutes and moves slower in the area of 15 minutes and 45 minutes. The two movable dials (FREE DIALS) are each driven per 1 gear wheel with a fitted eccentric cam and are designed in such a manner that they have their greatest lift in the area of 15 and 45 minutes. The dials move in the opposite direction to the hand, which increases the resolution of the time display and improves legibility. The mechanism of the minute indication is generally comprised of 2 groups. Group 1, the movable dials and group 2, the special hand. Due to the use of eccentric cams, which drive the hand and dials, in the course of 60 minutes, they move at varying speeds. The interaction between the hand and dials is designed in such a manner that at the point of high lift per minute of the hand, the dials move with a small lift per minute and vice versa. Each of the 2 dials is mounted on a separate support, which has a ball bearing mounted pivot point. The support to which the respective dial is secured has a weight on the opposite side and is designed in such a manner that the centre of gravity of the entire dial support group is located exactly above the ball bearing mounted pivot point.


HOURS
                                      DATE

The date is indicated through a large window at the top left. An additional date window is located on the opposite side on the right, which however is covered by a grill and has only been placed here in order to achieve visual symmetry.

GMT

The 24h ring (A) of the GMT display can be adjusted wit the left crown
in both directions at any time and completely independently.
The inner ring with the arrow (B) make 1 revolution in 24 hours
The dot (C) is positioned opposite the arrow and helps during the
GMT Display is covered by the minute mechanism. e.g. On the picture
the real GMT Time is 17H the dot shows 5h +12 = 17H)
  DAY & NIGHT


The fixed day&night disc (D) is located in the centre of the GMT
display with the indications for day and night. When the arrow
(of the GMT display) moves in the upper half of the disc, it is
day and when it moves in the lower half, it is night.
