I'M IN THE PROCESS OF ORDERING ANOTHER OF THESE WATCHES,JUST IN CASE I EVER WEAR THIS ONE OUT. I HAVE TRIED. I AM A PROFESSIONAL DIVER. I'M IN AND OUT OF THE OCEAN AND WORK WITH LOTS OF AIR-DRIVEN IMPACT TOOLS. I AM OVERLY TOUGH ON WATCHES AND MOST DO NOT LAST MORE THAN A YEAR ON MY WRIST. I'VE HAD THE MTG900DA G-SHOCK TOUGH SOLAR FOR FIVE YEARS NOW AND IT HAS NEVER FAILED. I REGULARLY DIVE TO 100 FT AND THE WATCH HAS NEVER LEAKED OR CLOUDED. THE CLASP WITH ITS LOCKING FEATURE IS VERY RELIABLE AND RUGGED. THE TIME IS ALWAYS CORRECT AND THE AUTO LIGHT FUNCTION HAS BEEN A LIFE SAVER. I RARELY IF EVER TAKE THE WATCH OFF AND IT HAS BECOME PART OF ME. I RELY ON THIS WATCH EVERY DAY.I HAVE OWNED LOTS OF RUGGED WATCHES; ROLEX, SEIKO DIVE WATCHES,TAG-HEUER AND NONE OF THEM CAN HOLD A CANDLE TO THIS WATCH FOR RUGGEDNESS AND RELIABILITY. IT IS A GREAT PIECE OF ENGINEERING. YOU SIMPLY CANNOT GO WRONG WITH THIS WATCH.
