Ressence Type 3 B

The Type 3 is the first ever oil-filled mechanical watch. A true achievement in Fine Watchmaking, the Type 3 is designed with a “water drop” dial effect in order to achieve crystal clear dial legibility for the wearer. Because oil and glass share very similar responses to light refraction, the eye is tricked into momentarily losing its depth perception. The result is that the watch’s dial seems ever closer, vision of it apparently unimpeded by glass at all.

The creation of the Type 3 was not without its challenges. One such example was the escapement ability to oscillate properly in a viscous fluid. Ressence ingeniously designed a two-chamber system inside the Type 3 to keep the mechanical movement and oil separate. As such with the two-chamber system, there is no direct mechanical link between the watch’s movement and the ROCS. To accommodate this, the Type 3 uses a magnetic transmission to tie the modules together. In order to compensate for oil volume fluctuation (dependent on temperature), the watch is also fitted with a system of seven small bellows that expand and contract dependent on the increase and decrease of the oil’s volume.
