MB&F HM12 The Guardian Gives the Horological Machine a Moving Face

MB&F has never treated the wristwatch as a flat instrument, and the HM12 The Guardian pushes that idea into properly theatrical territory.

This new Horological Machine looks less like a conventional timekeeper than the head of a small mechanical sentinel, with a spaceship-like titanium case, an animated face-shield and a companion body created with L’Epée.

It’s strange, technical and deliberately characterful, which is exactly where MB&F tends to be at its best.

At a glance

A Horological Machine with a character of its own

The HM12 The Guardian reconnects with the sci-fi energy that helped define MB&F’s earliest Horological Machines.

Rather than hiding its mechanics inside a traditional case profile, the watch builds a personality around them.

The grade 5 titanium case has the feel of a compact spacecraft, with the time display arranged symmetrically through jumping hours and trailing minutes.

At the top, a flying tourbillon takes visual command, while a micro-rotor carrying MB&F’s battle-axe motif sits within the mechanical architecture.

The effect is deliberately anthropomorphic without becoming cartoonish.

Seen head-on, the HM12 reads like a robot’s face, with its displays, case geometry and protective shield forming an expression rather than a simple dial layout.

The moving face-shield is the real theatre

The most distinctive element of the HM12 The Guardian is its mobile face-shield.

It can be activated on demand through a second crown, changing the watch’s expression and giving the object a sense of interaction rarely found in high-end mechanical watchmaking.

MB&F developed an independent mechanism for this shield, using more than 200 components for the animation alone.

That sits alongside an in-house-designed movement made from 646 elements, a project refined over four years of development.

For collectors who follow MB&F, that separation matters.

The shield isn’t just a decorative cover attached to the case, but a mechanical system with its own logic, purpose and tactile reward.

L’Epée turns the watch into a full mechanical guardian

The HM12 becomes more theatrical when paired with its L’Epée companion structure.

Standing 38.2 cm high and weighing 15 kg, the articulated architecture functions as far more than a display stand.

Place the watch at the top and it becomes the head of a larger mechanical creature, shifting the object from wristwatch to kinetic sculpture.

The L’Epée creation also integrates a mechanical thermometer, a magnifying loupe and a UV torch designed to reveal the watch’s luminescent decorations.

That mix of horology, display and interaction gives the HM12 a second life off the wrist, which feels particularly aligned with MB&F’s long-running interest in mechanical objects that don’t fit neatly into one category.

Details & Specifications

The HM12 The Guardian is aimed squarely at the collector who wants MB&F at its most imaginative, where engineering, sculpture and playfulness are treated as parts of the same machine.

It’s not a watch trying to disappear under a cuff, but a mechanical character built to be handled, displayed and remembered.
