Let there be light

HYT’s FLOW watches mirror the brand’s relentless quest to bring innovation that resonates with its contemporary context. Literally speaking, light brightens what already exists; figuratively it brings deeper understanding. The latter describes these timepieces’ purpose in the watchmaking arena. They are about the possibilities that emerge when performance enters new territories. Triggered by a pusher, a specially developed micro-generator stores and dispels the energy to activate 8 or 13 meticulously positioned LEDs, according to the version. These then visibly spread light evenly across the dial, mimicking a natural wave. Element by element, the illumination reveals the various “stories” that make up the piece’s time-telling capacity, never allowing us to lose sight of time’s unstoppable flow.


Two variations on the FLOW theme, both limited editions, play very different games with the emitted light.

On one, a dome of 73 baguette-cut 1.7-carat diamonds dances spectacularly to rhythms derived from the 13 LEDs below it. Just as time’s flow is constant, this unique horological light show is a theatre for continual, energized change uniting jewelry and light thanks to the dynamic reflection and refraction. Innovation meets beauty and quite literally dances the night away.

Another execution addresses the concept of infinity through a precisely tapered vortex shape. Here the imagination is invited to visualize a revolving, apparently never-ending flow down towards the bellows, as a side-aperture welcomes the light emitted by 8 LEDs. The limitlessness of infinity fits neatly into the focus on time’s inevitable transience.


Tension please

In the HYT FLOW, opposites do far more than attract – they form a rich source of design energy. An apparently contradictory combination of liquid and electric light set the scene; the bold asymmetrical shape of the 51 mm case and vibrant color choices pick up the thread. A visual wave sweeps around its side, reminding that stopping time’s momentum is never an option. This well-considered curve tempts the eye to explore new perspectives on time, a vital element of modern life.

Sophisticated electro-erosion

A ring of Super-LumiNova® documents the antithesis of night and day. Polished accents on the circular-brushed case underline specific elements such as bezel angles. This is an appropriate overture to the three-dimensional character of the opaline-finished grey dials, where “metallic” and “velvety” sit together comfortably in the descriptive dictionary. Sophisticated electro-erosion adds a further signature to the theme of tension with its use of electric current to physically cut out strips of metal to obtain the wave illusion. The high-energy appearance of the dials’ backgrounds contrasts with the calmer, more minimalistic time indication. Concave and convex surfaces tease each other, as the eye peeps behind the waves to catch a glimpse of the intriguing mechanical mechanism below.

It’s flow time. 24/7.
