Accurate timekeeping is assured by the installation of three advanced time-correction systems: terrestrial radio wave reception (Multi Band 6),
GPS satellite signal reception and Bluetooth® transmission.
The most appropriate system is selected automatically depending on the conditions,
and the correct time is displayed for the current time zone anywhere in the world.
Standard time radio wave reception
GPS satellite signal reception
Standard time radio waves are received by a tiny built-in antenna in Japan (Fukushima and Kyushu transmission stations), the United States, the UK, Germany and China, and the time is corrected automatically.
The GPS function enables the watch to acquire positioning and time-calibration data from GPS satellites. It analyzes the current time zone and Daylight Saving Time information and displays the correct time automatically.
The built-in Smartphone Link function uses (Bluetooth®) communications to connect to a smartphone and correct the time automatically four times a day. When crossing time zones, the watch displays the local time with one push of a button. It also uses information acquired via smartphone to update the global time difference and time zone information contained in the watch’s internal data.
A magnetic-resistant plate installed in the module prevents stoppage or shifting of the hands due to magnetic forces.
The introduction of a fiber insert resin band.
A functional layout of phosphorescent 3D hour markers along with three inset dials and two windows gives the multi-layered dial excellent visibility.
A high-transparency, abrasion-resistant sapphire crystal with a non-reflective coating is installed to ensure clear visibility.
Use of a carbon fiber material with low specific gravity for the second hand made it possible to enlarge it while maintaining its impact resistance.
A second disk capable of displaying various functions such as the current mode and day of the week is installed in addition to the date display disk.
The dial is illuminated by a high-brightness LED that ensures visibility in the dark.
A CASIO-original thin analog movement made possible by hybrid mounting protects against damage and enables auto home position correction that helps keep you on time all the time.
An electronic crown switch and the use of multiple motors combine to enable conflict-free simultaneous operation of multiple functions, and smooth switching between functions.
When GPS satellite signals are received, the current location’s latitude is displayed on an inset dial at 9 o'clock and the longitude in a window at 6 o'clock. The latitudes and longitudes of selected cities are also displayed when switching among World Time cities.
With the push of a button, the time display is switched to an inset dial at 6 o'clock and UTC (Coordinated Universal Time) is displayed in a window.
A shadow-dispersing solar panel realizes superior power-generation efficiency.
Six motors achieve nimble operation by driving the hands and disks independently. A disk at 6 o'clock and a disk in an inset dial are driven by two dual-coil motors, a system that enables original hand movements with speedier display times and varied hand movement speeds.
Developed exclusively for GRAVITYMASTER, the app updates information of time zones and DST.
- Flight Log function [Smartphone App]
Time point memories are input by button operation (time stamp). Location information is obtained by simultaneous connection to the smartphone and the point is marked on the map. The Flight Log is useful for reviewing travel history, including the point of departure, interim and final destinations, and return destination.
