MB&F has decided to auction one of the initial Legacy Machine No.1 (LM1) prototypes in celebration of the collection’s 10th anniversary. This one-of-a-kind timepiece marks the birth of the LM1 series, first presented in 2011. The end of the series was announced in 2017 with a Final Edition of 18 pieces, giving the MB&F team the time to explore other creative horological avenues. Since all the LM1 editions have now been sold, the only way to commemorate this important anniversary was one of the original prototypes. This LM1 “Longhorn” follows on from the HM4 Thunderbolt prototype, which was also sold on the 10th anniversary of the HM4 collection (in 2020) to one of the brand’s most avid collectors in a private sale. To make this second prototype sale fairer for all MB&F aficionados, MB&F founder Maximilian Büsser has decided to auction the piece at the sale organised in Geneva on November 7th (2021) by Phillips in Association with Bacs & Russo – and to donate a significant portion of the proceeds to Save The Rhino International.
