Teoricamente sim, os Bell&ROss em questão seriam da linha Hidromax, que foi testada em cameras hiperbaricas a 1.110bar (equivalentes a 11.000 metros); lembre-se que teoria não é igual a pratica, a estanqueidade em altas pressões nem sempre se traduz em estaquiedade sobre baixas pressões. Do site oficial pode-se ler em um PDF da linha: HYDROMAX® THE WATCH THAT STAYS WATER-RESISTANT AT DEPTHS OF 11100 M The Hydromax watch has been designed to perform in the most extreme underwater diving conditions. Tests in hyperbaric tanks have proved the watches’ resistance at 1110 bar, equivalent to 11100 metres. This performance is due to a major technical innovation: a watchcase completely filled with a transparent oil called Hydroil®. This liquid guarantees perfect water-resistance and incomparable readability. In addition, it guarantees extremely reliable and silent operation. To compensate for the Hydroil oil expanding or compressing in extreme differences of temperature, a special watch case system has been developed and patented by Bell & Ross (see diagram). Moulded at the centre of a screw-down back, a flexible rubber button “deflates” or “expands” according to variations in liquid volumes. A metal plate protects the mechanism from the deforming rubber. Exclusive user of Hydroil in watchmaking and the inventor of the special steel and rubber watch back, Bell & Ross has in the Hydromax an exceptional watch that satisfies the extreme requirements of deep underwater diving. *Tests carried out in cooperation with Ifremer (the French Marine Research Institute). ... To study the Hydromax’s resistance to hydrostatic pressure, several deep water immersion simulations have been carried out by Bell & Ross in cooperation with Ifremer (the French Marine Research Institute). The results of these tests have proved the watches’ resistance to pressure of 1200 bar, the equivalent of about 12,000 m, that is the deepest point on the earth, the Challenger Trench in the Pacific Mariana Islands Archipelago – exactly 11,100 m).
