The HM4 ‘Razzle Dazzle’ is quite simply one of the most radical Horological Machines ever; it belongs to the HM4 ‘Thunderbolt’ series, first launched in 2010 to the shock of the watchmaking world. The twin jet-engine design, inspired by airplanes, is unlike any other watch – and is echoed by the totally unconventional movement inside. Incredibly complex, it’s disarmingly user-friendly: one dial displays the time, the other the power reserve; just like a cockpit’s speed and fuel gauges.
The ‘Razzle Dazzle’ edition pushed the aircraft-inspiration to the max. Special features set it apart and make it a tribute to legendary WW2 aircraft: tiny titanium rivets on the fuselage, vintage-look dials, a strap crafted from vintage Swiss military bags… But most importantly, a hand-painted miniature of a pin-up, just like the nose-art painted on military aircraft by their crews – the result of weeks of work by miniature painter Isabelle Villa.
