In 2008, Glashütte Original debuted the PanoInverse XL, which presents the duplex swan-neck fine adjustment on the dial side of the watch.
The elaborately engraved balance bridge with its fine adjustment mechanism was presented for the first time on the dial side of a watch. This was made possible by the inverse arrangement of components that would normally be visible only through the sapphire crystal caseback. The off-center design of the Pano collection gives pride of place to the duplex swan-neck fine adjustment, the manufactory's own innovation. This device enables exceptionally precise adjustment of the watch's rate and centring of the oscillation system.
The obvious beauty of this perfectly realised functional element had inspired the engineers and designers to undertake a thorough re-design of the manual winding movement: they laid out the movement in such a way as to make the "butterfly", as the duplex swan-neck fine adjustment is also known, the centre of attention on the dial. To turn this idea into reality it was necessary to rework the design at a number of places in the movement, and to develop new components and subassemblies. As a result, of these new developments, all three plates, as well as the wheel train assemblies for the movement and power reserve, had to be reworked and adapted to the new configuration.
The debut versions in 2008 of the PanoInverse XL in white and rose gold were joined in 2010 by a version in stainless steel. Its galvanic anthracite three-quarter plate and butterfly bridge served as an especially splendid stage for the filigreed regulation system with its golden screw balance.
A further two models followed, once again after two years, each equipped with a larger, 42mm case and spacious dials. While the red gold version with blued steel hands was limited to 200 pieces, the PanoInverse in stainless steel with black dial ring, launched in 2012, continues today to offer fascinating views of its caliber 66-06 manual winding movement.
Thanks.
