Type 5 Ressence Watch “Grey”

TYPE 5 is the first mechanical watch to be perfectly readable underwater regardless of the viewing angle. Unlock the Gentlemen Diver in you.

As for all RESSENCE watches the essence of TYPE 5 is its main function – the expression of Time. To achieve the best-ever readability underwater, the complete ROCS 5 – all 142 components, including the dial – is immersed in 37.5 ml of oil. Indeed the use of oil has one ultimate advantage. It cancels out what is known as Total Internal Reflection. Typically, under water, a traditional diver’s watch needs to be viewed straight on in order to be read properly – otherwise refraction turns the glass into a mirror. But not with the oil-filled TYPE 5 . The use of oil ensures complete legibility whatever the angle of view. A first for a mechanical watch.
