Is GMT a diver watch?

Could you elaborate on whether GMT watches are considered to be diving watches? I understand GMT watches are designed for travelers to keep track of multiple time zones, but do they possess the necessary features and durability to be used as a diving watch? Are they waterproof to a certain depth? Do they have a rotating bezel for easy timing underwater? Or are GMT watches more suited for daily wear and travel purposes, rather than for diving activities? Clarifying this distinction would be valuable for potential buyers looking for a multi-functional watch.
