The automatic movement is highlighted by the astral skeleton structure and the micro‑rotor, offering a spectacular view on the mechanism. Not only aesthetics, the micro‑rotor offers a winding ratio as good as the best single‑direction big oscillating weight. Manufactured in Gold and titanium, the timepiece is the perfect match between a sporty and refined look. What is interesting with this timepiece is that you really have the perception of a precious gold watch (enhanced by the level of finishings, as sharp that on the movement), but with the lightness of a skeleted case combined with a titanium bezel.
