TYPE 5N NIGHT BLUE

TYPE 5 is the first mechanical watch to be perfectly readable underwater regardless of the viewing angle. UNLOCK the GENTLEMAN DIVER in you.

NO MIRROR REFLECTION UNDER WATER

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.

LIGHTNESS AND PERFORMANCE
Rather than protecting the TYPE 5 against the pressure of water depth by using a heavy over-sized case and thick glasses, we used our oil technology. Since the laws of hydraulics state that a liquid cannot be compressed, the oil will compensate for underwater pressure. TYPE 5 benefits therefore from a super lightweight titanium construction. Moreover there are other advantages related to the oil technology. The components are constantly lubricated and since they are suspended in liquid, they are lighter and hence require less power to move, which in turn improves accurate time-keeping.
