For sixteen years, every Ressence on a wrist has been driven by an ETA base. The Antwerp brand, founded in 2010 by Belgian industrial designer Benoît Mintiens, built its identity on the Orbital Convex System (ROCS): a module that replaces watch hands with three rotating discs, each orbiting the dial like a planet, each remaining flat to the surface so the markers always line up. The discs are graphic and beautiful. They are also expensive to drive. A 2824 or 2892 base, however heavily modified, was never quite designed to spin a convex titanium plate.
That changes with the Type 11. The new Werk RW-01 is the brand's first proprietary movement, designed in Antwerp and produced by Concepto in Switzerland. Ressence has been working toward this for years; the launch makes the Type 11 the first Ressence not built on borrowed architecture.
Werk RW-01: a triangular automatic, made for ROCS
The RW-01 has two visible departures from the modified ETAs that came before. The first is its shape. As Monochrome reports, the movement abandons the standard round architecture for a triangular plan, organised around three circles: two mainspring barrels and a centred balance. The two-barrel system delivers 60 hours of reserve, against 36 on the prior generation. The escapement runs at 4Hz with 40 jewels and 67 gears. The ROCS module now glides on 18 titanium ball bearings, integrated rather than bolted on top.
The second departure is the winding interface. Ressence has never had a crown. The brand's earlier watches asked the wearer to wind and set the time by rotating the entire caseback, with a set of instructions about speed and the risk of overwinding that became a recurring point in reviews. The RW-01 simplifies this with a hinged lever on the caseback. Lift the lever, wind the movement; lift it further, set the time. There is no more "winding zone" to find by feel.
The watch: 41mm of titanium with a new indicator on the dial
The Type 11 case is the familiar Ressence pebble: 41mm wide, 11mm thick, 45mm lug-to-lug, polished Grade 5 titanium, with a double-domed sapphire crystal that sits flush with the case. The convex titanium dial carries three rotating satellite sub-dials for hours, minutes and seconds. The brand quotes 30m water resistance.
The new movement enables a new indication on the front of the watch. Because the RW-01 has more energy to spare, the dial now carries a power reserve display, executed as Ressence does most things, by working around the medium rather than borrowing from it. Instead of an arc-and-pointer gauge, the indicator is a horseshoe of contrasting ceramic micro-balls. As the movement winds, the lighter balls advance into view; as the reserve drains, they retreat. It is the first dial-side complication on a Ressence in years.
Three colour options launch together: Pine, a deep green; Sky, a pale blue; and Latte, an off-white. Each dial is sunburst at the centre, circular-grained inside the hour and second sub-dials, and grain-finished on the outer minute track and the power reserve horseshoe. Buyers choose between four straps: leather, rubber, a leather and rubber hybrid, and a titanium Milanese mesh.
Where this lands
The Type 11 is the most complete Ressence the brand has shipped. It also closes a gap that has been part of every Ressence review since the brand's first Type 1: the watch is quietly remarkable on the wrist, but the movement underneath is borrowed. By doing the movement work in-house and shipping it with a longer reserve, a simpler winding interface, and a power reserve that respects the brand's design language, Ressence has gone from "design studio with great execution" to "design studio that owns its own architecture."
As SJX notes, the move also matters commercially. Independent brands at this price point face pressure from collectors who want to know the movement is theirs and not a generic base, and the timing aligns with Ressence's 16th anniversary. CHF 23,000 places the Type 11 above the discontinued Type 1 (CHF 16,500) but well under the limited-edition Type 8 carbon series that pushed past CHF 50,000.
The Type 11 reaches selected retailers worldwide and the Ressence e-shop from May 2026. Three references, three colours, one new movement. The brand's pebble silhouette is unchanged. Everything inside it is new.
