Belgian independent watchmaker Ressence has unveiled the TYPE 10 DN, a striking new timepiece that combines its signature oil filled display with a proprietary automatic movement for the first time. Named Dark Night, the limited edition pairs a deep blue finish with futuristic design and some seriously clever engineering, delivering a fresh take on the brand’s unconventional approach to telling the time.
Limited to just 100 pieces, the TYPE 10 DN is a bold evolution of Ressence’s distinctive design language, where traditional watchmaking conventions are replaced by fluid shapes, rotating displays and an almost uninterrupted visual surface.
A Seamless Design In Deep Blue
At first glance, the TYPE 10 DN looks more like a futuristic instrument than a conventional mechanical watch. Its 41.5mm case is crafted from Grade 5 titanium and finished with a deep blue, hard DLC coating, creating a monochromatic appearance that extends across the dial and integrated rubber strap.
The result is a cohesive, almost sculptural design that feels as though it has been shaped from a single piece of material. Ressence has paid particular attention to the details, too, with a fixed bezel constructed from 24 individual titanium segments. Alternating brushed and sandblasted finishes create subtle variations in the way light catches the surface, adding texture without disrupting the watch’s clean aesthetic.
The convex dial is where things become particularly interesting. Rather than relying on conventional hands, the TYPE 10 DN uses Ressence’s distinctive rotating display system, with indications that orbit across the dial to present the time in an unconventional yet visually intuitive way. The engraved markings are filled with Grade A Super LumiNova, ensuring the display remains legible when the lights go down.
Oil Filled Innovation Meets An In House Movement
The headline development is the combination of Ressence’s oil filled display with its proprietary RW 04 automatic movement. While the brand has already established its reputation for unconventional dial architecture, the TYPE 10 DN marks the first time one of its oil filled watches has been powered by a movement developed specifically for the brand.
At the heart of the watch is the RW 04 calibre, comprising 252 components and delivering a 60 hour power reserve through two barrels. Operating at 28,800 vibrations per hour, the movement drives the patented ROCS 10 module, which contains a further 196 components within the oil filled display chamber.
The engineering challenge lies in bringing these two environments together. The mechanical movement operates in air, while the display operates in oil. Ressence connects the two using a magnetic transmission system, allowing the movement to drive the display without a physical connection passing between the separately sealed chambers.
The oil filled architecture helps reduce light refraction, making the display appear closer to the surface of the crystal. The effect is one of depth and fluidity, with the rotating indications seemingly suspended beneath the glass rather than sitting on a conventional dial.
A temperature indication also monitors the oil’s operating range, while an expansion membrane compensates for changes in oil volume as temperatures fluctuate. It is a clever solution to a particularly unusual watchmaking challenge, and one that allows Ressence to retain the visual effect that has become central to its identity.
A Different Way To Read Time
The TYPE 10 DN displays hours and minutes alongside a second time zone and a 120 second running indicator. The latter also plays a role in the watch’s technical architecture, helping protect the magnetic transmission system against shocks.
As with other Ressence creations, the absence of conventional hands and a traditional dial layout gives the TYPE 10 DN a distinctly contemporary character. The rotating indications make the passage of time feel more like a moving graphical display than a series of familiar markers, reinforcing the impression that this is a watch designed from the ground up rather than adapted from an established template.
Despite the complexity beneath the surface, the watch weighs just 82 grams. Its integrated rubber strap and titanium pin buckle continue the deep blue aesthetic while keeping the overall package relatively lightweight.

Winding Things Up
The TYPE 10 DN is a fascinating next step for Ressence, bringing together two of its most distinctive strengths: an unconventional approach to displaying time and a willingness to rethink the mechanics behind it. The introduction of the RW 04 movement into an oil filled design is more than a technical milestone. It demonstrates how the brand is continuing to develop its own watchmaking capabilities while staying true to the visual identity that sets it apart.
With its deep blue finish, lightweight titanium construction and remarkably intricate display, the Dark Night is unlikely to appeal to anyone looking for a traditional dress watch. That, of course, is rather the point. Limited to 100 examples and priced at CHF 45,000 before taxes, this is a highly exclusive piece for collectors who prefer their horology with a healthy dose of experimentation.
And while the price will put it firmly into serious collector territory, the TYPE 10 DN offers something that money cannot easily buy elsewhere: a genuinely different perspective on what a mechanical watch can be.
