The 5000 composite band model is a brand new, specially crafted. Inspired by the first G-SHOCK model, DW5000C, this upgraded original boasts a modern upgraded approach while maintaining a vintage aesthetic. The watch also incorporates one of the first and most iconic G-SHOCK case designs, featuring a vintage, square shape case. The GMWB5000BC-1B incorporates a super illuminator LED light and solar battery – rendering it capable of self-charging, as well as a special STN LCD. Two-way time sync is made possible via Bluetooth Connectivity and the G-SHOCK app, as well as G-SHOCK’s Multi-Band 6 Atomic Timekeeping technology, which provides accurate timekeeping virtually anywhere via radio signals from up to six different transmitters worldwide.
