The design

A form that disappears on the wrist.

Milled from a single block of aerospace-grade aluminum, the case is finished by hand and sealed under Gorrila Glass. No screws on the face. No unnecessary seams. Two finishes, one shape.

Display1.39″ AMOLED, 454×454

Case41mm, aerospace aluminum

CrystalSapphire, scratch resistant

Capacity400 mAh

Processor230 MHz, ultra-low power

Materials

Every material was chosen for how it ages, not just how it photographs. Nothing plated, nothing painted — what you see is what the watch is made of, all the way through.

The software

An operating system with restraint.

Core OS was built from nothing, not adapted from a phone. It boots in under a second, runs for days on a single charge, and asks for your attention only when something actually needs it.

Instant response

Every tap registers in under 16 milliseconds — no spinner, ever.

Quiet by default

Notifications are opt-in per app. Most people enable three.

Works with any phone

Full functionality on iOS and Android, no ecosystem lock-in.

Health tracking

Continuous, silent, honest.

Core Watch 1 reads heart rate, sleep stages, and steps in the background, all day, without turning your wrist into a dashboard. Check in when you want to. It's tracking either way.

Heart rate

Optical sensor sampling every few seconds, resting to peak.

Sleep stages

Light, deep, and REM, tracked without a companion habit tracker.

Steps & activity

Counted quietly. No streaks to protect, no guilt notifications.

Resting heart rate

58 bpm

Battery

Charge less. Wear more.

Ultra-low-power hardware and a lightweight OS mean fewer nights on the charger.

Based on internal testing with always-on display disabled and typical notification use. Actual results vary with settings and usage.

Why Core

Designed with purpose.

Three decisions run through everything, from the case to the code.

Minimal hardware

Every part serves a deliberate function. A clean exterior chassis engineered with premium materials, nothing added for the sake of it.

Optimized software

A highly customized, lightweight OS built explicitly for immediate speed and ultra-low power draw — not a phone OS shrunk to fit.

Intelligent health

Continuous heart rate, step count, and sleep tracking, monitored silently and surfaced only when you ask.

Opt-in notifications

Nothing reaches your wrist unless you decide it should. No default noise to turn off on day one.

One update path

Software updates are small, tested, and reversible. No forced redesigns of a watch face you already learned.

Any phone, fully

Every feature works the same on iOS and Android. No half-supported ecosystem, no missing menu on one platform.

Questions

Before you ask.

When does Core Watch 1 ship?

We're finalizing manufacturing now. Waitlist members will get an invitation to pre-order in the order they joined, with shipping updates sent by email.

Does it work with my phone?

Yes. Core Watch 1 pairs with any iPhone or Android phone through the Core app, and every feature works identically on both.

Is there a subscription?

No. Every health and software feature is included with the watch, permanently. There's no premium tier hiding behind a monthly fee.

What sizes and colors are available?

Core Watch 1 ships in a single 41mm case size in Graphite and Silver finishes, with three included band lengths to fit most wrists.

How accurate is the health tracking?

Heart rate and sleep staging are validated against clinical-grade reference devices during development. Like all wrist sensors, accuracy can vary with fit and skin tone; we tune for consistency across both.
