A no-nonsense, helium-safe 1000-meter diver built to survive anything.
The Ratio Freediver V02 is a massive, overbuilt dive tool designed for people who want real capability for real adventure. With 1000M water resistance, a helium escape valve, sapphire crystal, and a rugged 46mm steel case, this thing is a tank. Powered by the Seiko NH36 with day/date and Diashock protection, it’s a reliable workhorse built to handle abuse. Not subtle — just tough.
