Full-Cataloguing
Good To Know:

- Made in a limited edition of 33 pieces
- Preserved in excellent condition

Founded in 2005 by Maximilian Büsser, MB&F has established itself at the forefront of independent watchmaking, producing some of the most technically ambitious and visually arresting horological creations of the 21st century. Blurring the boundaries between engineering and art, the brand’s Horological Machines consistently challenge conventional notions of form, mechanics, and display.
Inspired by the fluid dynamism of mid-century automotive and aviation design, the HM9 Flow evokes the architecture of a jet engine, featuring a fully in-house movement of remarkable sophistication. Two independent balance wheels beat on either side of the watch, their rates mechanically averaged by a central planetary differential to deliver a single, stable time indication.
Limited edition of 33 pieces only, the present HM9 Flow Titanium Road Edition features a complex case composed of sapphire crystal, titanium, and pink gold movement, representing a significant leap forward in case construction and redefining both structural and aesthetic possibilities in contemporary watchmaking. Despite its striking external appearance, MB&F founder Maximilian Büsser described the engine inside HM9 as “the most beautiful movement we’ve created to date”.
Please note that MB&F generously offers a complementary servicing of the watch to the winning bidder within a period of 6 months after the sale.
