Overview

Built in the Micro Artist Studio in Shiojiri, the small workshop Seiko reserves for its most involved work. The 9R01 runs eight days on one barrel arrangement, and it manages that partly through a torque return system that captures energy the mainspring would otherwise waste and feeds it back to the glide wheel.

Notable
  • Eight days of reserve, with the remaining power shown on the dial rather than the movement side.
Common questions

Before you ask.

What movement does the Grand Seiko SBGD201 use?

The Grand Seiko SBGD201 runs the 9R01, a spring drive movement.

How do I check a Grand Seiko SBGD201 with Watch Safe?

Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
