## Caption

In 1943, Jacques Cousteau and Émile Gagnan patented the Aqua-Lung — the first open-circuit #SCUBA system.

Since then, an estimated 9 million certified #divers worldwide have descended beneath the surface, unlocking an entirely new frontier of human exploration.

The original #divecomputer wasn’t digital. It was mechanical. A watch built to measure the one variable you couldn’t afford to lose. That lineage runs straight through the tool watches of today.

Marathon’s #SAR line was engineered for military and professional divers, built to international dive standards, pressure-tested, and legible at depth.

Long before screens and sensors, there was steel, lume, and a bezel.
