Ressence Type 3W White Limited Edition of 100 Pieces.
The Ressence Type 3 transports time from the dial to the crystal. The orbiting indications are bathed in a fluid that refracts light like air, so that the indications appear to be displayed directly onto the sapphire crystal closer to the eye of the beholder. The high-contrast white indicators against the black dial appear to be projected onto the top crystal as if onto a screen. Type 3 offers a tangible feeling of being able to touch time itself.
The indications and their mechanisms are mounted inside a bubble crafted from extremely tough, anti-reflective sapphire crystal. The complication and indications follow the shape of the crystal. The mechanism (44 gears, 77 jewels and 347 components) is enclosed in an upper compartment filled with a naphtha-type liquid that has a more similar index of refraction to the sapphire crystal than air does. Refraction bends light when it passes from one material to another, e.g. air-to-glass or glass-to-air. With the fluid-filled dial indications, refraction is greatly minimised, which tricks the brain into seeing the dial in two-dimensions rather than three. A thermal valve automatically adjusts for any expansion or contraction of the fluid.
This version includes a mechanical thermal gauge to indicate the optimal running temperature for the oil. The 0.5 millimeter bi-metal spiral is mounted 0.1 mm under the discs to capture the slightest temperature changes inside the oil, which can range from -5 C to 55 C (23F to 131F).
