Price available upon request
The MB&F HM5 RT (55.RL.B) is a horological marvel, seamlessly blending vintage inspiration with avant-garde design. Crafted in 18k red gold and titanium, its distinctive case measures 51.5 x 49 x 22.5mm. While its exterior pays homage to 1970s supercars and the Amida Digitrend, its inner workings surprise with a water-resistant container, shielding the intricate mechanical engine. The bi-directional jumping hours and trailing minutes are ingeniously displayed by a sapphire crystal prism, magnifying numerals by 20%. Waterproof louvres and exhaust pipes add functionality to the futuristic design. Limited to 66 pieces, the HM5 RT is a unique fusion of nostalgia and cutting-edge craftsmanship.

After decades conforming to the rules of corporate watchmaking, Maximilian Büsser broke the chains and started a rebellion in 2005; a rebellion called MB&F – Maximilian Büsser & Friends.

MB&F Watch Brand History

Maximilian Büsser started his rebellious move in the world of fine watchmaking in 2005, deciding to go against all rules of traditional, corporate watchmaking. He wanted to create something so utterly different that they wouldn’t even be called watches, they’d be called Machines. Despite the futuristic designs of the brands, Maximilian Büsser’s concept was about warmth, and friends, a concept that ran so deep, it’s part of the brand’s name: Maximilian Büsser & Friends. The artistic concept was based around the simple idea of developing radical horological masterpieces. The desire was never to disrespect tradition, and the long, imposing heritage of haute horlogerie, but rather to reinterpret it, to bring it to modern times, and take it even further, into the future. In 2007, MB&F unveils its first Horological Machine, HM1, a record breaker in the world of luxury watches, followed by new, revolutionary models each and every year.
