H. Moser & Cie and MB&F unveil new unique watch for ONLY WATCH charity

Edouard Meylan and his team at H. Moser & Cie. are long-term partners and contributors to many MB&F Machines. The friendship already resulted in extremely successful double collaboration in 2020, with the MB&F x H. Moser LM101 and H.Moser x MB&F Endeavour Cylindrical Tourbillon. Today the two independent watchmakers unveil a new watch - this time for charity.

The two brands have created for the 2023 edition of Only Watch charity auction a very rare watch (even more rare than wildlife panda bears that inspire the playful creation and its story). The Pièce Unique H. MOSER X MB&F STREAMLINER PANDAMONIUM will rise funds for Only Watch auction that has been relentlessly raising funds since 2005 for research on Duchenne Muscular Dystrophy, a fatal genetic disease that progressively weakens children’s muscles.

The Streamliner Pandamonium is a mix of both brands’ worlds, with signature elements from both sides: you’ll first notice H. Moser’s Streamliner case and a fumé dial in a brand-new colourway, stripped of logos and indices, in H. Moser’s typical minimalist style. Their minute repeater complication has been significantly modified to host our unmistakable flying balance wheel, floating under a sapphire crystal dome. And last but not least, the chiming mechanism is led by a miniature DJ panda, a creature that has become a mascot of MB&F creations for Only Watch.

MB&F's original panda was created for Only Watch 2011 – as an allegory about the children suffering of Duchenne Muscular Dystrophy, of those children’s dreams... The panda returned in 2021 before making its third appearance now in 2023, this time inviting those children to escape their condition by immersing themselves in music, losing touch with reality for a few beats.

Placed alongside the hammers, the panda seems to be mixing, its turntables rotating as the hammers strike the time. Made entirely by hand from white gold, at a height of just 5.35 mm, the miniature figurine took countless hours of precision work to create, from the design and development phase, to modelling then manufacturing, followed by time at the hands of the engraver, then the jeweller for the final polishing – not forgetting the meticulous painting.

Maximilian Büsser and Edouard Meylan revealed the piece in a press conference today at the Geneva Watch Days for the gathered press and online guests.

The Streamliner Pandamonium will embark in a few days, along with all the other unique pieces, for the Only Watch world tour – culminating at the auction itself on November 5th in Geneva.
