G-SHOCK IS A TOUGH WATCH THAT WON'T BREAK EVEN IF DROPPED, AND SINCE ITS DEBUT IN 1983, G-SHOCK HAS ENHANCED ITS SPECIFICATIONS AND INTRODUCED NEW TECHNOLOGIES SUCH AS "TOUGH SOLAR," WHICH COMBINES SOLAR PANELS AND RECHARGEABLE BATTERIES, "MULTI BAND 6," WHICH AUTOMATICALLY CORRECTS THE TIME USING STANDARD RADIO WAVES, AND A FUNCTION THAT LINKS IT TO A SMARTPHONE.
TODAY, THE SQUARE 5600 SERIES, WHICH HAS CONTINUED FROM THE FIRST MODEL, REMAINS POPULAR. INCLUDING THE GMW-B5000, THE FIRST FULLY METALIZED VERSION OF THE SAME FORM, THE HIGH-END MR-G, AND THE SOPHISTICATED MT-G, A FUSION OF RESIN AND METAL, TOTAL SHIPMENTS ARE EXPECTED TO REACH 130 MILLION UNITS BY 2021.
