PANEL is an instrument cluster for your wrist. Six small rings sit quietly in the corner of the face and only speak up when something actually needs you. THE RINGS - Every ring has three states, and they are drawn so you can tell them apart at a glance: a hairline arc when the reading is fine and you can ignore it, a solid arc while it is in progress, and an inverted badge when it is time to act. - Only three readings can raise a badge, because only three have a threshold that published work supports. A face that alarms every day is not information, it is background noise. - M — sitting. Fills over 30 minutes, not an hour. A 2024 meta-analysis of 13 randomised trials found that interrupting sitting every 30 minutes with a short walk lowers post-meal glucose, while hourly breaks do not. Garmin's own move bar runs on an hourly cycle, so PANEL keeps its own. - R — Body Battery, flagged below 25, Garmin's own "low" band. - B — watch battery, flagged below 20 percent. - The other three (daylight, steps, heart rate) show where you are and nothing more. A watch face should not issue medical warnings. - Ten marks around each ring at ten percent intervals, so you can count how full it is instead of guessing. - The seconds keep running in low power, so the register is never showing a stale number. TIME - One row, as large as the case allows, in a typeface baked for this screen. Digit width and stroke weight were chosen by measuring which pairs of numerals become confusable at a distance, with the glare of white-on-black included. - A seconds register: a hairline track with the elapsed part drawn over it in a heavy arc, and the exact second in the middle. Two layers, nothing else. - A date-time group along the bottom edge, in the standard DDHHMMZ MON YY form, set in black on a white plate so the zone boundary is a surface and not a suffix. The large time and the date are local; only the plate is UTC. - Date in army, ISO 8601, US or ordinal form. Every one of them carries the year, because the date-time group does. CHOICES - Two of the six rings can be reassigned: daylight can become calories or floors, heart rate can become stress or pulse ox. Daylight needs a position fix, so anyone who never has one gets a ring that works. - The sitting alert can be switched off. The reading stays; only the prompt goes. WHAT IT WILL NOT DO No invented numbers. When a reading is unavailable the ring says so instead of drawing a zero. No focus score, no readiness index built from data that cannot support one. Pure black and white, drawn pixel by pixel for the 1-bit display, and checked against a measured map of which pixels the case actually leaves visible.
