Case study · Watch OS · Layers Electronics

Designing an operating system for a 1.85-inch screen.

Anarc 2 arrived as a style frame and a partial screen set. What it needed was an operating system. This is how it got one: about 460 screens designed against a memory budget, a battery ceiling, and a price that moved while we were building it.

Roughly 460 of these. The watch, and the interface that runs on it.

Seymourpowell’s handover → what shipped

Who checked it

Before UI lock, I put it in front of 400 people.

I wrote the survey, called about a hundred of the people who answered, and sat down with 18 of them in person, at our office in Delhi and on site in Vadodara.

Most of the design held up. The icon set didn’t: people rejected the version we had been leaning towards, so we changed it.

01 Battery

Every watchface gets an always‑on twin. The rule for it is mine.

On an AMOLED screen a black pixel costs nothing and every lit one drains the battery. I wrote the rule every always-on face follows: keep the time and one accent, drop the rest. More than 200 faces ship on Anarc 2, most drawn by other people, and all of them follow it.

Result Workout screens got their own always-on state, a first in our price segment.

02 AI

Neither AI feature was in the brief. Both shipped.

I designed Layers AI and Canvas AI end to end. Canvas AI turns one spoken line, like “a cute puppy with polka dots”, into a watchface on your wrist. A watch mishears, and generating a face takes time, so nothing installs without two checks: it reads back what it heard, then shows you the face first.

Result Two features outside the original scope, both live on Anarc 2 as beta.

03 On the body

Tap and hold worked in Figma. On a raised arm, it didn’t.

Layers AI first asked you to hold the screen while you spoke. On an internal build, with my arm up and a long question, it got uncomfortable fast. It’s now tap to start, tap again to stop.

Result On-wrist testing moved earlier for every feature after it.

04 Storage

The activity badges take more room than the heart rate monitor. We kept them.

Our ODM partner keeps a table of what every module costs. The four badges that appear when you close a goal come to about 33 MB, more than heart rate, blood oxygen and stress together. They’re the screens people show each other, so I compressed them instead of cutting them.

Result Capped, not cut. The smallest version that still felt like a celebration.

Where it landed

Shipped on 21 September 2026, at ₹6,999.

There’s no launch data yet. The first number I’d look for is how many people leave always-on switched on, because that’s the real test of the trade we made.

With more budget, I’d have kept the steel case and pushed for auto workout detection and better sensors. Most of the gap to the best watches isn’t taste. It’s budget, sensors and time.

Still curious? The whole process is below.

11 chapters: price, research, battery, storage, health, icons and themes, the China trips, and six months of testing
