The basic design remains the same as the quartz model, but a see-through back is used to fully enjoy the mechanical pleasure. The brand logo is engraved on the crown, making it an exquisite piece with thorough attention to quality. The mechanical movement of the hands has a romance that cannot be found in the 1-second movement. When fully charged, it will run for about 41 hours (if you wear it, the pendulum movement will further extend the drive time).
