Bell & Ross Hydromax Professional 11100m Quartz

The Hydromax is equipped with some impressive technical features.

Bell and Ross use a watch case completely filled with a special type of transparent silicone oil called Hydroil to protect the watch from the huge pressures.

Since temperature fluctuations cause this oil to expand and compress, Bell and Ross developed a special patented watch case designed to compensate for this by using a rubber section in the case back that automatically adjusts (see image below)

A nice added benefit of using an oil filled design is that the refractive index of the oil makes the watch viewable from any angle underwater.

Bell and Ross in co-operation with the French Marine Institute carried out deep water immersion simulations in order to study the Hydromax’s water resistance and develop a watch capable of reaching great depth.
