MAIN PLATES
More than 50 processes go into
making a single main plate
The main plate is the base to which all the different
components of a movement are attached. A large
number of processes, from pressing and washing,
go into the manufacturing of main plates.
The main plate of the MIYOTA 82 Series
mechanical movement is a good example.
It requires over 50 separate processes.
(Some other main plates require as many as 70!)
As the framework that holds together all the other
high-precision parts, the main plate itself need to be
highly precise. That is why we make both the dies for
pressing and the tools for milling our main plates in-house.
Like a master chef presenting
a signature dish with exquisite plating,
creating amovement that keeps
accurate time requires arranging
multiple delicate and precise parts in
just the right position. That is why
zero-defect quality is an absolute must.
