The Satellite hour watch features rotating numeral disks that orbit like satellites, combined with fixed markers to indicate the time. It has a MIYOTA movement with an in-house satellite hour module. To prevent the backlash characteristic of the satellite hour mechanism, the hour disk is driven by a double reduction gear. Additionally, to highlight the static satellite hour mechanism, careful design has been utilized to ensure the movement of the mechanics is clearly visible. First, the hour disk directly engages with a ball bearing roller at the 8 o’clock position, allowing for instantaneous switching twice per hour, similar to a jumping hour mechanism. The seconds disk at the 5 o’clock position constantly moves regardless of the hour disk’s position, providing a continuous view of its mechanism.

To emphasize the three-dimensional shape of the satellite hour mechanism, a high-profile box sapphire crystal is used, with the case edge lowered to the maximum extent. The case thickness is 7.6 mm, while the height of the box sapphire crystal is 4.6 mm. Each component housed within the sapphire crystal, including the “minute index plate” and “hour disk”, is designed to cast distinct shadows.
