I have decided to test to the limit a poor G-Shock , the model I have choosen for this test is the DW-9052
Frozen during 48 hours at -18°C
Boilled in hot water (100°C) for 10 minutes
Temperature cycle test : -40°C/+70°C rapid variation and 1 hour to top/min temp : 5 cycles :
Vaccum test : watch in a vaccum chamber (normally used for thin film coatings) for 24 hours and return to ambiant pressure
Gas pressure test : the watch is pressurised at + 2 Bars, then return to ambiant pressure
Cryogenic test : the watch is vaporised with a coolant agent giving peak temperatures at -65°C
Washing machine test : the watch get a full cycle in a waching machine :
Diving test : the watch is regulary test during my dives, max depth -40 meters (picture here taken in a diving pool at -20 meters)
compression test : I drive my range rover over the G-Shock (click to read the video)
and guess what ?
The G-Shock perfectly survive to ALL thoses tests !
