An advanced micro magnetic transmission to connect the two separate sealed chambers of TYPE 3 and TYPE 5.



The ROCS's are driven by the minute axle of a customised 2824/2 base calibre.

As, in the TYPE 3 and the TYPE 5, the ROCS is physically separated from the rest of the watch - because it is suspended in oil - we developed a unique magnetic transmission. Several micro magnets, connected to each other, are positioned inside the upper half and the lower half. That way the minute information can be transmitted from the base calibre to the ROCS even if the magnets are separated by a titanium grade 5 membrane.


We use extra small magnets measuring only 1 mm diameter and 0.5 mm thick. They are physically positioned far from the regulating organ.

We developed extra strong magnetic conductors to reduce the spread of magnetic fields. They concentrate the fields in loops around the magnets.

The residual fields are deflected by a specially designed alloy protecting the regulating organ in the same way that a Faraday cage would do for electro-magnetic fields.
