Why it is interesting

Perhaps the most unusual object here: case architecture becomes the way the wearer interacts with the movement.

Things to consider

The 23 mm height and 20 m water resistance limit everyday versatility; production is limited.

The model in detail

Introduced in 2023, HM11 Architect resembles a miniature building. A flying tourbillon turns beneath a central sapphire dome, surrounded by four rooms containing displays and a crown.

One room shows time, another power reserve, a third temperature, and the fourth houses a transparent sapphire crown. The owner rotates the case to bring the desired room into view.

That rotation also winds the movement: instead of the usual winding through a crown, the entire construction moves. The stated power reserve is 96 hours.

The Grade 5 titanium case is 42 mm in diameter but 23 mm tall. The original two Architect versions were limited to 25 pieces each; 20 m water resistance underlines its character as a collector’s piece.
