The **Horological Machine no. 1** is a watch of very unusual design from [[MB&F]].

Introduced in [[2006]], the HM1 was the first product of MB&F and established the company's credentials as the preeminent producer of avant garde timepieces. It is at once unique in form and advanced technically, setting the stage for future products from [[Max Büsser]] and friends.

Technically speaking, the HM1 is a [[four barrel]] watch with two independent dials meeting in a figure eight at a centrally-mounted [[flying]] [[tourbillon]]. The [[movement]] was developed by [[Laurent Besse]] and [[Peter Speake-Marin]] and is unlike anything previously produced. It features two pairs of [[barrel]]s, with those on the left [[automatic]]ally wound and those on the right [[manually wound]] using the [[crown]]. The four operate in parallel, connected through a beryllium gear train and producing seven days of power reserve.

On the dial side are a 12 hour dial on the left and 60 minute dial on the right. The minute-side dial includes a concentric [[power reserve indicator]]. The dials "communicate" using an ultra-thin mirror-polished gear beneath each face which is supported by jeweled bearings rather than the central hub.

Just 100 examples of the Horological Machine no. 1 were produced.
