Casio G-Shock GMW-B5000 Watches

Simplified version of the notorious GMW-B5000 series – steel flagship with Bluetooth synchronization. Cult square case with modern advanced stuffing is a gift for G-Shock fans. Bluetooth is used to synchronize the time and set the functions of the watch, control is performed on a smartphone in a special application G-Shock Connected. A redundant way to correct the time is Multiband radio synchronization, which is based on receiving radio waves from towers located around the world. No need to worry about a dead battery – the GW-B5600 has a solar battery, which is recharged from daylight. Day of week is displayed on the digital display in 5 different languages: English, Spanish, French, German, Italian, Russian. Basic functionality is also available – timer, stopwatch, alarm, world time, calendar and backlight.

Official Marketing Focus from Casio

Ever since the first DW-5000C, G-SHOCK has been constantly setting new standards in innovative design, tough structure, and powerful modules. Now to mark the 2018 35th Anniversary of the G-SHOCK come the GMW-B5000, a full-metal G-SHOCK with a Connected engine.
This model is full-metal version of the DW-5000 base model which represents a refinement of the hollow case structure to achieve an even higher level of shock resistance. Fine resin shock absorbers between the metal bezel and case created a shock resistant structure for a full-metal case. Innovative new band connections, which are components subjected to the strongest shock levels, add additional center lugs that lessen the load on the band pins. The screw back case, with a highly wear resistant diamond like coating (DLC), gives the watch a feeling of heft.
