Ressence spent four years on the TYPE 10 Dark Night, and the result is a watch in which the joins have been designed away. The case runs into the strap, the sapphire follows the curve beneath it, and case, dial and integrated rubber strap share a single deep shade, Dark Night Blue. The edition is limited to 100 pieces.

The ROCS discs turn in oil, so close to the crystal that they look printed on it, while the RW-04, Ressence's in-house self-winding calibre, beats in a dry chamber behind. Magnets link the two through the titanium case without them ever touching. The display gives a second time zone, a 120-second runner that doubles as a shock absorber, and a colour-coded indication of the oil's temperature.

Inside, 538 components make up the watch; on the wrist, it weighs 82 grams. Benoît Mintiens' studio in Antwerp calls the principle Simplication, which in practice means keeping all the complexity inside and leaving only the time to read.
