Horological Machine No6 SV (SV for “Sapphire Vision”) adds an extra three-dimensional layer to the biomorphic beauty of the HM6 ‘Space Pirate’ by revealing the mechanical marvels of the unique Engine within. The complex curves of two transparent sapphire crystal plates sandwich a precious metal "streamliner" case band, creating two horological amphitheatres dedicated to the appreciation of exquisite, hand-finished micro engineering.
A central dome houses a 60-second flying tourbillon, the precision regulator of the HM6 Engine. However, high-precision regulators are especially sensitive to changes in oil viscosity, and ultra violet radiation gradually breaks down lubricating oils. This is why HM6 features a retractable, semi-spherical, titanium protective shield; when closed, it blocks harmful radiation from prematurely oxidising the lubrication oils in the regulator. A crown at 9 o'clock opens and closes the cover in – and like–the blink of an eye.
Horological Machine No.6 ‘SV’ is a limited edition of 10 pieces in platinum/sapphire crystal and 10 pieces in red gold/sapphire crystal.
