THIS IS THE SECOND G SHOCK MTG900 THAT I HAVE OWNED, AND I FIND THAT THE BANDS WEAR OUT BEFORE THE WATCHES. I'VE BEEN IN THE CONSTRUCTION INDUSTRY FOR 33 YEARS AND HAVE LOST A MIRIAD OF WATCHES TO CONCRETE AND FLYING COME -ALONGS.THIS WATCH IS AS TOUGH AS ANY I HAVE OWNED AND QUITE FRANKLY, I AM AFRAID TO BUY ANY OTHERS. I HAVE USED IT IN SEWAGE AND HAVE BURNT IT IN A 3 PHASE ELECTRICAL PANEL(NEITHER ARE RECOMMENDED) MY 6 YEAR OLD WATCH BAND HAS BROKE 4 TIMES IN THE LAST MONTH AND I'M TOO BUSY TO GET A NEW BAND FROM A LOCAL WATCH SHOP. IF YOU NEED A WATCH THAT PERFORMS IN ANY CONDITION AND CLEANS UP QUITE WELL, THIS IS A GREAT CHOICE
