Here's an icon of the 1960s that you don't see in this excellent condition very often: An Aquadive 100 Atmos diver.
Big. Blue. Awesome.
Check out the ocean-blue and turquoise bezel, the azure Scotchguard dial, those white hands and markers...
And not for the faint of wrist: this is a massive 50mm wide, excluding the unsigned, screw-down crown. The bezel is unidirectional.
The unsigned stainless steel diver-style band fits a 7.5 inch wrist comfortably.
The automatic movement keeps excellent time. Quickset date works fine.
Strap it on and prepare for stares.
