3. V-groove Circular Rail Design
The final in the “Metal Cube Box” uses a V-groove bearing arrangement in which a
stainless steel ring is supported by four small, plastic-covered ball-bearings with V-
grooves to match the outer periphery of the ring. The stainless steel ring is attached to
the chronometer gimbals. The motion is transmitted from a servo motor via a linkage,
as in previous designs. The ring is cut to allow space for the chronometer to be tilted
forward for manual winding. The V-groove design solves the deficiencies of the
previous designs.
