Chronos-Bio redraws your day as a single circle. The outer ring is a full
24 hours — midnight at the top, running clockwise — split into 96 fifteen-
minute blocks. Each elapsed block is coloured by what your body was doing:

• BLUE — sleep and recovery
• AMBER — physical activity / raised heart rate
• GREEN — rest, low stress
• ORANGE — higher stress or load
• DIM GREY — still to come, or no data yet

The blocks are back-filled from Garmin's own stress and heart-rate history
and your sleep schedule, and every elapsed block is cached on the watch, so
the timeline keeps its shape all day — even across a reboot.

Around that band sits a clean analog clock: 12 rim markers with 12/3/6/9
emphasised, and high-contrast floating hands that taper to a sharp point and
never cover the centre readout. In the middle: your live Body Battery (or
Stress score), the date, and the watch battery. A dotted tick gauge along
the bottom tracks a goal of your choice — steps, floors, active minutes or
Body Battery.

Long-press the face to open a legend that explains every colour.

Built for memory-in-pixel (MIP) displays: an exact 64-colour-safe palette,
one code path for the 240 / 260 / 280 round buckets, and all sensor work
done once per minute in lock-step with the clock to stay light on the
battery. Optionally stays fully rendered in low-power mode on non-AMOLED
watches.

Settings (phone Connect IQ app or the on-watch menu):
– Center readout: Body Battery, Stress score, or off
– Bottom gauge: off, steps, floors, active minutes, or Body Battery
– Rest / stress split: 25 / 40 / 50 / 65 (50 = Garmin's rest+low band)
– Activity HR threshold: auto (from resting HR) or 90–130 bpm
– Date line, battery %, hour separators, long-press hint — each on/off
– Always-on full face in low power (ignored on burn-in-protection screens)
