MB&F returns to the Only Watch charity auction in 2011 with another emotionally charged piece – this time in collaboration with Chinese artist Huang Hankang.

HM4 Only Watch features a solid gold panda bear riding on top of the HM4 jet, which he controls with reins made of twisted gossamer filaments made of gold.

The panda was hand-carved and then cast in 18k white gold using the “lost wax” technique.

And while the HM4 Only Watch is a celebration of the fantasy of children’s dreams, there is also a feature for those obliged to ground their feet in reality from time to time.

The panda and his reins have been micro-engineered to be completely detachable so that HM4 transforms from a flying machine into a Horological Machine.
