The all-new G-Shock AWG-M520 series will launch in March 2021 in Japan with three models: the origin-inspired AWG-M520-1AJF (23,000 JPY plus tax), the all black AWG-M520BB-1AJF (24,000 JPY), and the black and rose gold AWG-M520G-1A9JF (24,000 JPY). Like the updated AW-500 series, the AWG-M520 is based on the first G-Shock with an analog-digital display, but with upgraded features like Tough Solar and Multi-Band 6. Feature-wise, it is the same as the full metal AWM-500 series (both use Module 6540), but the AWG-M520 is housed in a resin case with a resin bezel and band (and does not have a screw-back like the AWM-500).
Features include shock resistance, 200-meter water resistance, Tough Solar power, Multi-Band 6 auto radio-sync timekeeping, hand shift function, 1/100-second stopwatch (60 minutes total, with split), countdown timer (100 minutes), 5 alarms, hourly time signal, battery level indicator, power saving function, button tone on/off, and Super Illuminator double LED light with afterglow (1.5/3 seconds). Although they look very similar in design to the updated AW-500 models, the AWG-M520-1A has gray markers instead of white and also an inverted LCD display, and the other two AWG-M520 models also have the 15, 30, and 45 numbers on the dial.
The AW-500 series was only released in Japan, Asia, and the Middle East, so we are not expecting the AWG-M520 series to be released worldwide.
Update: The AWG-M520 series is not being released in other Asian countries in March, so it looks like it will remain a Japan-only release.
