Maurice Lacroix - Masterpiece Square Wheel Retrograde 43 mm - MP7158-SS001

A square wheel? It sounds a crazy concept, especially when
you consider that it was expected to turn and interface
with another wheel located adjacent and that second wheel
was clover-shaped. However, Michel Vermot, a watchmaker
and engineer at Maurice Lacroix, invented this concept.

The teeth on the two unusually shaped wheels would have
to mesh perfectly to ensure reliable operation. Each tooth
would require a unique angle to engage faultlessly without
any loss in power transmission. Initially, the technology
to create the unusually shaped, and very com- plex, wheels
did not exist and the idea was simply recorded on paper.

LIGA, a German acronym for Lithographie Galvanoformung Abformung,
a state-of the art process, provided the solution for creating
the small unusually shaped wheels. In collaboration with
the Haute Ecole Arc, based in Le Locle, the ground-breaking
design became a reality.
