Official description

With the One Hertz Fire, the One Hertz dial has been radiantly reinterpreted in a more casual/muscular layout, with flame-coloured touches that contrast against the dark 
grey background and blackened hand. 
 
The hour and minute subdial at 2 o’clock features an electrifying orange crosshair and number 12 and bright white chapter ring. The raised seconds sapphire subdial – transparent over the hour and minute subdial – features metallised indices on a resplendent orange background, with a striking inner ensemble of white circles and arcs.
 
In a scorching shade of orange, the power reserve indicator at 11 o’clock – now outside of the large seconds – and the setting-winding indicator at 3 o’clock look like 
two leaping sparks. The stark orange-on-black Grönefeld logo at 5 o’clock neatly complements  the orange stitching on the hand-sewn matte black strap.
