“You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.”

Buckminster Fuller

I hardly ever look at my watch to tell the time. I look at it to be amazed. Amazed by the design, the technical achievement and our most successful innovation; the capturing of time. HYT takes the journey to an other dimension, beyond time. With HYT the journey goes deep into space.

HYT 1
An encounter between Fine Watchmaking and fluid mechanics. One might say a utopia. Shattering all certainties, steamrollering conformity, the idea that led to the H1 was simple and consisted of two flexible reservoirs fixed to each end of a capillary. In one was an aqueous liquid filled with fluorescein, and in the other, a transparent viscous liquid. To keep them separate: the repulsive force of the molecules in each liquid, with a meniscus to mark the boundary between the two.

As the hours go by, the fluorescent liquid advances. The meniscus, in the shape of a half moon, marks the breaking point with the other fluid in the tube, indicating the time. At 18:00, the fluorescent liquid comes back to its original position, going backwards. The secret that gets the reservoirs going? Two bellows made of a highly resistant, flexible electro-deposited alloy, each driven by a piston. And this is where watchmaking comes in to activate the system.

A MECHANICAL MOVEMENT
TO ACTIVATE THE HYDRO SYSTEM

Orchestrated by Bruno Moutarlier, alongside Jean-François Mojon and his Chronode SA team, a mechanical movement is situated in the upper part of the watch, and propels a cam, which pushes the piston and activates the bellows.

The main challenge lay in finding an interface between the mechanical movement and the hydro system in a closed, waterproof circuit – a task further complicated by the limited space available to house them both. They had to be assembled separately to keep them independent, and then made to operate simultaneously. This is a highly delicate modular integration, which involves other constraints, such as the installation of the dial in two parts, through the sides.

BELLOWS
The secret force driving the reservoirs is two bellows made of a highly resistant, flexible electro-deposited alloy, each driven by a piston. And this is where watchmaking comes in to activate the system.

RESERVOIRS
The two reservoirs at 6 o’clock. While the first compresses, the second expands, and the other way round, resulting in the movement of the liquid in the capillary. The two bellows made of a Highly resistant, flexible electro-deposited alloy, each driven by a piston.

CAPILLARY & FLUID
Every microlitre counts, and the total volume in the closed circuit is extremely precise, as the system has to have a nanotechnology-worthy level of water resistance. Due to the unusual link between the crown and the liquid, a special time-setting system was designed in order to avoid the liquid moving around too fast and damaging the meniscus
