Brands like Rolex and Omega will often tout their deepsea capabilities with the Rolex Deepsea Challenge rated to 11,000 meters (36,090 feet) and the Omega Ultra Deep coming in at a lesser but still ridiculous 6,000 meters (20,000 feet) of theoretical water resistance. But what about a cheap Casio often associated with terrorists and hipsters? With around $15 and some engineering know-how, can an affordable watch also venture into the deep ocean?
I’ve taken mine surfing and snorkeling many times without ever thinking twice about getting it wet and it still looks and functions perfectly after something like 16 years. I’d say no oil is needed for any practical purposes, but it’s still interesting to test the limits.
If it ever does break, they’re cheap to replace. I’ll be sad when they finally stop making them though.
