JUVEIL PREMIUM V1
A new language of presence
Light and touch for the few things you choose to keep close.
DESIGN AND FORM
The technology follows the jewellery.
JUVEIL’s long, asymmetric Soft Meridian form is shaped around what sits inside it — not built around a visible module.
- GRADE 2 TITANIUM
- Light in wear. Strong in form. Finished with restraint.
- TWO-PIECE FORM
- A principal arc and slimmer opening arc meet as one continuous silhouette.
- MECHANICAL CLASP
- Opposed side pushers release the bangle without adding a digital control.
- RELAXED FIT
- Designed to rest like jewellery rather than grip like a sports band.

LUMINOUS SIGNAL SURFACE
A continuous surface, not a display.
Neutral and opaline in stillness. Luminous only when needed.
Concealed illumination creates controlled colour and movement without exposed emitters, segmented windows, icons or text.




LIGHT BENEATH THE SURFACE
A signal can have a place as well as a colour.
Five invisible positions give JUVEIL a sense of location and direction.
A signature can appear in one place, gather across 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.
JUVEIL COMPANION
Choose the signal. Leave the rest behind.
Choose who and what can reach JUVEIL. Build a signature. Test it. Decide 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, your signals can be tailored to suit the moment.

LOCAL BY DEFAULT
The signal can stay close to you.
For basic signalling, notification content is designed to remain off JUVEIL servers by default.
QUIETLY CONNECTED
Bluetooth is integrated without interrupting the luminous jewellery surface. NFC can support deliberate steps such as onboarding, while ongoing event communication remains with Bluetooth.
Optional cloud services may support backup, sync, remote automation and service under explicit controls.

POWER AND SERVICE
Made for days between charges.
JUVEIL uses power for a continuous connection and brief signals rather than an always-on display.
- RUNTIME TARGET
- At least 10 measured days of normal use, with 14 days retained as a stretch objective.
- MAGNETIC SADDLE CRADLE
- Two recessed underside contacts meet a keyed USB-C charging cradle.
MATERIALS AND SPECIFICATION
Made to be looked at in stillness.
The titanium follows a fine directional satin around the exterior and softens against the wrist.
The signal surface returns to neutral opaline when inactive.
