Setup, Compatibility & Care
To begin using the watch, familiarize yourself with the four side buttons to cycle through the digital display modes. Ensure the analog hands are synchronized with the digital time by following the 'hand home position' calibration process outlined in the official manual. Regarding care, the watch is designed to be low-maintenance; however, it should be rinsed with fresh water after exposure to saltwater to prevent long-term corrosion on the bezel or buttons. Keep the watch away from extremely strong magnetic fields, which can interfere with the quartz movement accuracy.
