1. G-shock watches are made of expensive material. Nowadays, g-shock watches are made of titanium which can not only reduce the weight of the watches but can withstand extreme conditions like water pressure and heat up to 200 degrees Celsius (392 degrees Fahrenheit), which in turn, makes watches more durable.

The model of your G-Shock watch will determine the internal packaging of your G-Shock watch to be either cardboard or tin encased. Check for a barcode on the outer cardboard packaging, as all original G-Shock watches will have a barcode displayed on their packaging that also matches the model number of the watch.

Electronically, they should be the same, unless you are paying extra for advanced features like barometer or altimeter, etc. All Casio watches are rugged and should last for years of continuous use. G-Shock takes the concept a step further by adding additional rugged features and elevating build quality.
