Among the independent brands officially exhibiting at Watches & Wonders, Ressence was a standout. The design-forward Belgian independent took a major step forward with the Type 11, powered by the brand’s first proprietary calibre, the RW-01. The Type 11 is tangibly appealing and priced well considering both its unique design and technical content.

Initial thoughts

When I first saw images of the Type 11 and its RW-01 movement, I had the same feeling as when Urwerk launched the EMC back in 2013. At the time, the EMC felt like the start of a new era for a brand that had, up to that point, primarily put its proprietary modules atop widely available off-the-shelf calibres. The EMC proved Urwerk was willing to rethink the movement in its entirety to realise a specific vision.

The RW-01 reveals Ressence is moving in that same direction. After 15 years of adapting its Ressence Orbital Convex System (ROCS) modules to ETA-derived calibres, the brand has taken the next step in its development and partnered with an adept supplier to construct a proprietary movement uniquely suited to its signature design.

The new calibre was engineered with Ressence’s ROCS module in mind. The movement layout appears purpose-built for winding and setting via the case back, lacking an ordinary stem, and dual serially coupled mainspring barrels extend the power reserve to 60 hours — quite long considering the mass of the ROCS module.

While I would have been delighted to see a free-sprung balance, I’m satisfied with the trade-offs that were made in construction, which focused efforts on the areas most likely to provide a tangible benefit to the user — namely the power reserve and user interface. The attractive, industrial finishing is also more than adequate for this segment in general, especially considering the RW-01’s raison d’être lies elsewhere.

It helps that the movement debuts in a trio of attractive liveries, and in an appealing 41 mm size that feels just right — easily wearable, but big enough to let the brand’s unusual regulator-style dial room to breath. The grey/brown, green, and blue colourways — Latte, Pine, and Sky — are each appealing in their own way.

The straightforward palette is sensible, as is the choice to offer a selection. It must have been tempting to launch the RW-01 in a limited edition with a higher price tag to accelerate the return on investment for the new movement, especially in today’s market that supports lofty valuations for watches from independent watchmakers. Instead, Ressence has priced the Type 11 competitively at just CHF23,000, offering a trio of well-priced hits.

A pebble on the wrist

The Type 11 is constructed from a lightweight combination of grade 5 titanium and sapphire crystal, shaped into a pebble-like case that’s 41 mm and 11 mm thick. Thanks to its bezel-less design — which also lacks a crown — the case effectively disappears on the wrist save for the simple polished lugs protruding at the corners.

Without a traditional crown, the movement is wound and set via a rotating case back. On some Ressence models, this is not so easy — at times it can be hard to get a good grip. But the Type 11 is among the models with a flip-up tab built into the case back, which makes winding and setting a breeze — each action is accomplished by rotating the case back in a different direction.

The winding tab helps overcome the resistance of the gaskets, which now support a depth rating of 30 m. This is up from just 10 m for prior Ressence models without screw-locked case backs. While the brand’s other watches are capable of exceeding their 10 m test depth, the conservative rating is intended to account for a degree of gasket decline and the loosening of tolerances over time.

In this context, the Type 11’s 30 m rating is both believable and welcome, and should widen the brand’s appeal among collectors looking for an original design from an independent watchmaker that they can wear daily.

Though most of the movement is concealed behind a solid case back, a small kidney-shaped porthole allows a peak at the RW-01 movement, and the rim of the rotor as it races past the window.

A familiar face

The signature Ressence dial can take some getting used to, but once accustomed it becomes highly legible. The entire dial is a rotating panel with a fixed minute hand, making one revolution per hour. The sub-dials for the hour, seconds, and power reserve float in the ROCS planetary gear set, staying level at all times.

It’s a fascinating look truly unlike anything else in watchmaking, and the ‘travelling’ aspect of the sub-dials gives the watch a different personality throughout each hour.

Both of the smaller sub-dials are notable for different reasons. Starting with the seconds, some earlier Ressence models lacked the ability to display running seconds, opting instead for a six-minute ‘running’ indicator. The running indicator on the Type 11 is a little more lively with a 90-second rotation.

The power reserve indicator is even more interesting, with a first-of-its-kind display that uses a continuous series of ceramic balls — in three colours — to indicate the state of wind. Only a segment is visible at any given time, and the excess is channeled through a hidden maze behind the centre of the gauge.

The ceramic ball race brings a degree of three-dimensionality to a design that can, at times, look almost as flat as an electronic smart watch screen. The state of wind is indicated by the colours of the visible balls — when almost all the balls are white, the movement is fully wound. As the movement unwinds, the white balls disappear and grey ones take their place.

The power reserve itself is also notable for its length. For the sake of comparison, the Ressence Type 3 Marc Newson offers a mere 36 hours of power reserve, making the Type 11’s 60 hours seem like an eternity. This type of gain fully justifies the move up to a proprietary calibre, to say nothing of the simplified process for winding and setting.
