It's a tool that also helps you keep track of time underwater or above it, under limiting conditions. It's corrosion-resistant stainless-steel throughout, so soak it as much in saltwater or alcohol as you want. Off the sea, this freediver watch even fits in with the most elegant of white suits. The helium valve is associated with compressions/decompressions at varied depths.
