Selection reference · illustrative scenario
Clock roles in the application
Watch timekeeping, processing, display, sensing and wireless functions have different reference needs. Build the clock list from the actual feature set.
Engineering selection review
Alongside package size, review clock inputs, battery states, wake behavior and calibration. Sensing and connectivity experience are system outcomes, not source-only improvement claims.
Procurement and documentation
Include soc, sensors and wireless module and dimensions, height and footprint, plus the existing full code, sample and production quantities and delivery target. Discuss nominated international brands and domestic candidates separately, confirming parameters and documents by part.
Illustrative validation scenario
Test wake recovery, timing, connectivity and power in representative modes, recording charging and battery conditions.
