Numerous connoisseurs have suggested that the exquisite characteristics of the manufacture calibres should be showcased in a particularly exposed position. Thanks to the inventiveness of Grossmann’s engineers, this was consummately accomplished with the calibre 107.0 movement. Here, pure watchmaking artistry has gained a new presence.

So far, highlights such as the Grossmann balance, the hand-engraved balance cock or the ratchet wheel with three-band snailing could only be admired through the display back. Now, with the development of the mirrored calibre, they can be shown on the dial side. This model presents the “back page” of the movement in an unusually large dial aperture that doubles as a prominent stage. The BACKPAGE comes in an 18-watch limited edition in platinum as well as in rose gold.
