SINGAPORE (Nov 19): Two leagues under the sea or 11,100m, rather — that is the unfathomable depth achieved by the Hydromax, the diver’s watch Bell & Ross debuted in 1997 to survive the most extreme conditions of deep-sea diving. Surface light penetration expires at 200m, after which there is nothing but pitch black darkness and a hostile environment in which only the hardiest of bacteria can survive.

Able to withstand a phenomenal nine tonnes of pressure per square inch, the Hydromax broke a world record with water resistance of up to 11,100m. With its extraordinary specifications, it could theoretically be used to explore the Challenger Deep in the Mariana Trench, the deepest known point in the Earth’s oceans.

Most diver’s watches would implode at a fraction of the depth and pressure the Hydromax is capable of withstanding. A case filled with patented transparent oil, known as Hydroil, protects the timepiece underwater without interfering with the operations of the calibre 955.162, a quartz movement with a five-year battery life. While impressive, few divers will ever achieve the depths that would necessitate such specs. Having proved its expertise and catered for elite deep-sea explorers, Bell & Ross has since refined its diving releases to practical and increasingly sophisticated collectibles.
