The mirror image calibre 107.0 makes the mechanism of the Backpage visible on the dial side. Through a large aperture, the characteristic movement details such as the Grossmann balance wheel, the hand-engraved balance cock or the ratchet wheel with three-band snailing can all be observed while on the wrist. The fully surrounding minute scale and an hour display from eleven to five o’clock serve as a framework for the moving ­calibre presentation. The imposed hour indexes and numerals in gold correspond to the colour of the case which is in rose gold. The lowered screwed ring of the small second hand displays the sophisticated bearing of the second hand shaft with a screwed gold chaton.
