Form factor

Not a watch.
A gauntlet.

A smartwatch is constrained by the size of a watch face. Sola is not a smartwatch. It extends beyond the face — toward the forearm — to give the display the space it needs to do what a phone does.

This is what the next form factor looks like. Not smaller than a phone. Worn differently than one.

The watch face is the wrong constraint.

Every smartwatch that has tried to replace a phone has failed at the same point: the display is too small. The watch face — designed for a clock, adopted for computing — constrains the screen to roughly the size of a large postage stamp.

You cannot read comfortably on it. You cannot type on it. You cannot navigate a map with real context. The form factor that works for telling the time does not work for replacing the computer in your pocket.

Sola breaks from this constraint. The display extends beyond the traditional watch face toward the forearm — treating the wrist not as a clock mounting point, but as a display and interaction surface.

Why the forearm is the right surface.

Flat and stable

The inner forearm is one of the flattest surfaces on the human body — ideal for a display that needs to be read without curvature distorting the image. Unlike the curved outer wrist, the inner forearm provides a natural mounting surface for a screen that needs to be legible.

Naturally oriented toward your line of sight

When you raise your wrist to check a watch, you turn your forearm toward your face. The inner forearm, extended, faces directly toward you in this position — putting a display there means it is oriented exactly where your eyes go when you glance at your wrist.

Proven in the field

Military and industrial users have worn wrist-mounted displays on the forearm for decades — soldiers use them for navigation and comms; field technicians use them for hands-free data access; medical personnel use them for patient information at the point of care. The form factor works. What changes with Sola is who it is designed for.

More wearable than it looks

A device that covers more wrist distributes its weight across a larger contact area. This can be more comfortable than a heavy watch concentrated at a single pressure point. The gauntlet form factor, designed correctly, is lighter on the wrist than a heavy dive watch — because the mass is spread.

Beyond the display

The gauntlet as
control surface.

Sola is not just a display worn on the wrist. Through Kin, the Sola gauntlet becomes the control surface for every device in your life. One surface. Every device. Always on your body.

01

Your devices, from your wrist

Robot vacuum. Thermostat. Washing machine. Security system. Every device connected to Kin responds to Sola. You do not need to find an app, unlock a phone, and navigate to a control screen. You raise your wrist and the device responds.

02

Kin knows what you need before you ask

The gauntlet surface is not just reactive — it is proactive. Kin surfaces the right device control at the right moment: when you arrive home, when your schedule changes, when something in your environment needs attention. The wrist is where Kin speaks to you.

03

One surface replaces twenty-two apps

Every smart device today ships with its own app. Sola — through Kin — replaces all of them. The gauntlet surface is the single interface for every device you own. Not because it mirrors them all, but because Kin already knows what each device needs to know about you.

04

Hands free. Always.

The gauntlet form factor means your hands are free while you interact with your environment. You can control a device, check a message, navigate, or pay — without holding anything, without reaching for anything. The control surface is on you.

The wrist-mounted display has always been for serious use.

Gauntlet and forearm-mounted displays are not new. They have existed at the edge of consumer awareness for decades — used in contexts where performance matters more than appearance.

MilitaryNavigation, comms, and mission data accessible hands-free in the field. Wrist-mounted displays have been standard equipment in special operations units since the 1990s.
IndustrialField technicians, engineers, and logistics workers use forearm-mounted displays for hands-free access to schematics, inventory, and instructions — in environments where holding a phone or tablet is impractical.
MedicalClinical staff use wrist-mounted displays for patient information at the point of care — enabling access to records without putting down equipment or breaking sterile procedure.
Extreme sportDivers, mountaineers, and endurance athletes use wrist-mounted computers for real-time environmental data — a category that has long understood that a phone cannot go where a wrist device can.

Sola brings this form factor — proven in the field, refined in professional use — into daily consumer life. The difference is not the form factor. It is who it is designed for.

A gauntlet is not a gadget.

The word “gauntlet” has started to appear in consumer wearable technology — mostly attached to modular devices with snap-on accessories: flashlights, pepper spray, cameras. These are gadgets in gauntlet form.

Sola is the opposite approach. The Sola gauntlet is minimal, not maximal. No snap-on modules. No physical accessories. The power is not in what attaches to the outside — it is in what Kin knows and what Kin controls. The gauntlet form factor exists to serve the display and the intelligence, not the other way around.

FAQ

Questions about the form factor

What is a wrist gauntlet?

A wrist gauntlet is a wearable computing device that extends beyond the traditional watch form factor — covering more of the wrist and forearm to accommodate a larger display, more capable hardware, and a more ergonomic control surface. Unlike a smartwatch, which is constrained to the small face of a watch, a wrist gauntlet treats the wrist and lower forearm as a display and interaction surface. Sola is built around this form factor.

How is a wrist gauntlet different from a smartwatch?

A smartwatch is constrained by the circular or rectangular watch face — typically 40–49mm. A wrist gauntlet extends that surface toward the forearm, giving the display more area, the hardware more room, and the user a more capable interaction surface. The result is a device that can genuinely replace a smartphone, rather than one that merely complements it.

Why does extending toward the forearm matter?

Display size is the single biggest constraint on what a wrist-worn device can do. A watch face is too small for comfortable reading, typing, and navigation. By extending toward the forearm, Sola gains the display area needed to replace a phone without the form factor becoming impractical to wear. The forearm is flat, stable, and naturally oriented toward the user's line of sight when raised — ideal for a display.

Is the Sola gauntlet form factor comfortable to wear all day?

Sola is designed for all-day wrist wear. The gauntlet form factor distributes weight across a larger contact area than a watch, which can actually improve comfort compared to a heavy watch concentrated at a single point. Materials, weight distribution, and strap design are engineered for daily use across all activities.

Does Sola control other devices through the gauntlet?

Yes. Through Kin — the personal entity that powers Sola — the gauntlet becomes a control surface for every device in your life. Your robot vacuum, thermostat, security system, washing machine, and any device integrated with Kin responds to Sola. The gauntlet is not just a display for your own information; it is the interface for your entire connected environment.

Has the gauntlet form factor been used before?

Wrist-mounted displays have a long history in military and industrial applications — soldiers carry wrist-mounted tablets for navigation and comms; field technicians use forearm-mounted displays for hands-free access to data. What is new with Sola is applying this proven form factor to a consumer device designed for daily life — not specialized field use.
