Yamamoto Manufacturing has, for many years, been a leader in the field of watch casings, covering every step from the creation of dummy samples to mass production.
Drawing on the know-how accrued through this experience, we can support your metalworking operation from prototyping to mass production.
We can be involved from the component design stage and can meet your needs with a one-stop solution that encompasses everything from design and manufacture to surface finishing and embedding.

Before
•The management of outsourced processes is cumbersome.
•Quality is unstable because processes are managed individually.
|
Streamlining with a single source for multiple processes •Outsourced processes are more easily managed.
