A company called Swiss Military Watch – I’ve never heard of them – ran their heavy duty diver through a few clever tests including a blast from a fire hose and a close, personal connection to a stick of dynamite.
The model in question, the 20,000 feet looks pretty hefty and includes a nice 7750 Valjoux movement with COSC certification. It has a large crown, heavy side cards, and is made mostly of titanium. Also it’s like $4428, not amazingly bad for a Valjoux COSC-certified chrono. Plus you can shoot it.
