Three JUVEIL bangles on a desk showing blue, ivory and yellow signal states.

JUVEIL PREMIUM V1

Light and touch, made personal.

A screenless bracelet for the signals you choose.

DESIGN AND FORM

The technology follows the jewellery.

The Soft Meridian form contains light, connection and mechanics within one asymmetric silhouette.

GRADE 2 TITANIUM
A restrained satin finish gives the surface its character.
TWO-PIECE FORM
Two arcs meet as one continuous form.
MECHANICAL CLASP
Two discreet pushers open the bangle while keeping the interaction entirely mechanical.
RELAXED FIT
Designed to sit naturally around the wrist.

LUMINOUS SIGNAL SURFACE

A continuous surface, not a display.

Neutral and opaline at rest. Luminous when a signal appears.

Colour and movement emerge beneath the surface, without exposed emitters, segmented windows, icons or text.

LIGHT BENEATH THE SURFACE

A signal can have a place as well as a colour.

Five concealed positions determine where a signature appears within the arc.

A signal can appear in one place, span several or travel through the arc.

COLOUR AND MOVEMENT

Colour gives identity. Movement gives form.

White, Green, Yellow, Red and Blue form the core palette.

Pulse, Double, Travel and Breath shape the way each signature appears.

PULSE
One rise. One return.
DOUBLE
Two close beats.
TRAVEL
Movement through the arc.
BREATH
A slow expansion and release.

SIGNAL & TOUCH

Learn a few. Know them well.

A signature can combine colour, position, movement, direction and touch.

Light and touch can arrive together, or a signal can be felt without light.

CHOSEN PERSON
A familiar signature for someone you choose.
IMPORTANT MOMENT
A cue for something you want to notice.
NEXT MOMENT
A quiet signal when it is time to move, prepare or join.
HOME
A selected event at home, given a signal of its own.
YOUR OWN RULE
A signal for a rule you define yourself.
ARRIVAL
A quiet cue when something you have been waiting for arrives.

JUVEIL COMPANION

Shape the signal around the moment.

Choose who or what can reach JUVEIL. Build the signature. Test it. Set how it should behave in different contexts.

WHEN
something selected happens
IN
a context you allow
THEN
JUVEIL delivers the signature you chose

From focused hours to quieter evenings, the same signal can adapt to the context you set.

LOCAL BY DEFAULT

Personal signalling, kept local.

For basic signalling, notification content is designed to remain off JUVEIL servers by default.

QUIETLY CONNECTED

Bluetooth carries the ongoing connection without interrupting the luminous surface. NFC supports deliberate steps such as onboarding.

Optional cloud services may support backup, sync, remote automation and service under explicit controls.

POWER AND SERVICE

Power without becoming the point.

JUVEIL is designed around brief signals and a continuous connection, without an always-on display.

RUNTIME TARGET
Development is targeting at least 10 days of normal use, with 14 days remaining the stretch objective.
MAGNETIC SADDLE CRADLE
A compact saddle cradle is designed to meet two recessed contacts beneath the bracelet and connect through USB-C.

MATERIALS AND SPECIFICATION

Character at rest.

A fine directional satin defines the titanium exterior, with a softer finish against the wrist.

The signal surface returns to neutral opaline when inactive.
