Ressence is one of the lesser known, very small independent watchmakers who have been making waves within the cognoscenti. The watches are catagorised by Types – the Type 1, the Type 3 and the most complicated (to date) the Type 5. This release for SIHH 2017 is the new grey dial for the Type 5.
The Ressence Type 5G
The case remains all titanium and like the other members of the Type 5 family is has true underwater capability…the catch phrase from Ressence is “for the gentleman diver, whether he’s in the water or in town.”
The Type 5 is the only mechanical watch to be perfectly readable underwater regardless of the viewing angle. Sinn makes an EZM 2, which makes the same readability claim, but the Sinn is equipped with a quartz movement.
Typically, when under the 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 an oil-filled watch: this gives it complete legibility whatever the angle of view. To enable readability under water at all angles, the Sinn EZM2 fills the entire space inside the case with a silicon oil. This brings the added benefit of a big depth rating…Sinn calculates it to be 11,000ft without having to use a huge case and crystal like the Rolex Deep Sea Challenge does.
In the case of the Ressence, the case is divided into parts, the upper part which includes the dial and module, is completely filled with oil (37.5ml), making use of total internal reflection to enable the full dial to be visible underwater at any angle. The lower part houses a regular ETA 2824/2 modified to drive a magnetic transmission system to connect the two separate sealed chambers. And though the dial sits some distance from the upper sapphire glass, the liquid makes it look like the dial is on the underside of the glass.
There are other advantages too: the oil keeps the 142 components of the ROCS (in-house patented complication module) constantly lubricated. And since they are suspended in a liquid, they are lighter and hence require less power to move, which in turn improves time-keeping. The result is a watch both functional and more ergonomic than traditional diver’s pieces.
The Type 5G is designed to be able to withstand extreme conditions.
Dial and case become one. The titanium discs, rings and bezel are all microbilled and amplify the visual impact of the unique all grey look. The watch’s appearance is fresh and modern Extra strong blue SuperLuminova ensures the readability of the Type 5 in all lighting conditions.
The organic design of the Type 5 takes its inspiration from nature, specifically sea turtles. Their distinct aqua-dynamic shape means they are best able to propel themselves easily through the water. An apt design inspiration for an amphibious watch.
Type 5 capitalises on the 6 Ressence technical solutions based on physical principles: Display by discs, No crown, Oil-filled, Bellow system, Magnetic transmission and Hydraulic shock absorber (sea above for more details).
The Type 5 is available in three executions:
-Type 5B, black dial and polished/satin titanium finish.
-Type 5BB, black dial and black DLC finish.
-Type 5G, grey dial and polished/microbilled titanium finish (this release).
