THE ULTIMATE DIVING UTILITY Before scuba gear ever existed, the only way to explore the depths of the ocean was by holding one’s breath. Free diving without oxygen tanks is the ultimate expression of freedom and the pinnacle test of lung strength. As a nod to the fortitude of free divers, we named this model the Iron Lung. When designing, we wanted to embody the rawness of free diving by giving it a high lume dial with minimal markings. Oversized hands finished with Swiss Super-LumiNova make reading this watch with just a glance, totally effortless. Keeping the seconds separate from the hour and minute hands by utilizing a sub seconds ensures there are no mistakes reading the dive bezel while 30 feet under. Finished with an anti-glare curved sapphire crystal, the Iron Lung is the ultimate expression of diving freedom.
