The world-proof diver watch
NO MIRROR REFLECTION UNDER WATER
As for all Ressence watches the expression of Time is fundamental. To achieve the best-ever readability underwater, the complete ROCS 5 module is immersed in 3.57 ml of oil. The use of oil 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. The use of oil inside the TYPE 5 ensures complete legibility whatever the angle of view. A first for a mechanical watch.
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. 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.
The remarkable capabilities of TYPE 5 do not sacrifice the pleasures of a traditional fine-watchmaking mechanism. The watch is able to withstand extreme conditions - but to do so with the modernist refinement characteristics of Ressence, right down to its seamlessly integrated uni-directional bezel.
It takes 324 components and Ressence’s state-of-the-art innovations for the TYPE 5 to express Time in such a pure and natural way. From our magnetic transmission to the bellow system, explore on our innovation page the technologies that are embedded.
However, to ensure maximum water resistance, a new case-back has been specially developed for the TYPE 5. Dubbed the Ressence Compression Lock System, or RCLS, it has a system for the locking and compression of the gasket, with two positions, ‘lock’ and ‘set’.
The organic design of the TYPE 5 takes its inspiration from nature. Evolution has given sea turtles a distinct aqua-dynamic shape to propel themselves easily through water - so what better shape for an amphibious watch? Strapped onto your thermal suit, the TYPE 5 will conform to your wrist to guarantee optimum hydrodynamic properties.
The TYPE 5 has been designed to be wearable every day, both in and out of the water. The TYPE 5 is made 100% from grade 5 titanium, ensuring that it is lightweight - a mere 87grams - and extremely comfortable to wear. The result is both more ergonomic and considerably lighter than any traditional diver’s watch.
HOW DOES IT WORK?
The patented ROCS 5 is driven by the minute axle of a customized self winding 2824/2 base calibre. Our "Ressence Orbital Convex System" is a state of the art horological complication module composed of 142 parts including the main and sub discs. The result is a 3 dimensional dial entirely in motion and ever changing.
