Following the release of the all-new GW-B5600 Series in Japan and Asia, Casio America announced the G-Shock GWB5600BC-1B for a November 2018 release with a list price of $200 USD. The GWB5600BC-1B is a basic black origin-inspired model with stealth bezel lettering, a clean symmetrical face design, a reverse LCD display, and a resin-link composite band with a 3-fold clasp.
The GWB5600BC-1B has the same internal features as the popular full-metal GMW-B5000 series including Tough Solar power, Multi-Band 6 radio wave timekeeping, and Bluetooth mobile link. Externally, this model has a resin exterior and does not have the upgraded STN LCD display of the GMW-B5000 series. An advantage of the GWB5600BC-1B is its lighter weight at 85 grams versus 167 grams for the full-metal GMW-B5000.
By linking to the G-Shock Connected app on a smartphone, the Bluetooth link offers automatic time adjustment, 300-city world time with 5 settable world time cities, reminder alerts with text description (for certain dates, a range of days, or days of the week), a time & place mapping log, and a phone finder function. Other unique features over other square 5600 models include the ability to change the month/date order (such as to DD/MM) and the day of the week abbreviation is available in six languages.
The watch can be operated with or without using Bluetooth at all. We recently covered the Bluetooth features of the GMW-B5000 and GW-B5600 and highly recommend using Bluetooth, as using the G-Shock Connected app makes adjusting the settings a lot simpler and offers additional features. If battery usage is a concern, automatic time adjustment can be disabled so that any feature requiring Bluetooth must be initiated by the user. Other features include shock resistance, 200-meter water resistance, 5 daily alarms with 1 snooze alarm, 1/100 second stopwatch, countdown timer, power saving mode, low battery alert, and full auto Super Illuminator LED light with adjustable afterglow.
