Step 01
Comprehensive verification of incoming touchscreens, AMOLED panels, optical sensors, silicon straps, and precision enclosures against engineering drawings and AQL II standards.
Step 02
Shielded radio-frequency (RF) evaluation analyzing pairing stability, antenna gain, data transmission throughput, and clear voice calling across iOS and Android ecosystems.
Step 03
Pressure differential testing verifies that sealing gaskets, acoustic membranes, and optical sensor lenses meet IP67 and IP68 dust- and water-ingress specifications.
Step 04
Devices undergo prolonged dynamic active screen operation, continuous sensor polling, and processor load stress to eliminate premature component infant mortality.
Step 05
Replicates multi-axis harmonic vibration encountered during international air cargo, ocean shipping, and overland freight to verify packaged structural integrity.
Step 06
Automated tumbling barrel tests verify mechanical chassis rigidity, display bonding adhesion, and internal sensor mounting integrity under repeated low-altitude impacts.
Step 07
Evaluates the electrochemical corrosion resistance of zinc alloy, aluminum, stainless steel cases, PVD plating, and magnetic Pogo-pin charging contacts.
Step 08
Precision environmental chamber cycling from -20°C to +60°C with up to 95% relative humidity to ensure reliable operation in diverse global climates.
Step 09
Specialized dry thermal baking checks the heat tolerance of lithium batteries, structural glues, silicone watchbands, and internal PCB solder joints.
Step 10
Controlled free-fall drops onto steel and marble surfaces from 1.0 to 1.5 meters from 6 orientations to verify screen shatter resistance and internal PCBA shock absorption.
Step 11
Hydrostatic immersion tank subjecting wearables to physical water column pressure, verifying seal resilience around acoustic apertures, buttons, and heart-rate windows.
Step 12
Applies high-voltage electrical stress between external conductive parts and internal circuits to eliminate electrical leakage risk and ensure user dermal safety.
Step 13
Precision electrostatic discharge simulator applying contact and air discharges to verify that microcontrollers, PPG sensors, and touch ICs remain immune to static shocks.
Step 14
Multi-channel battery grading apparatus measuring true milliampere-hour (mAh) capacity, internal impedance, and discharge consistency for each pure cobalt cell.
Step 15
Repetitive torsion, strap bending, buckle clamping, and magnetic charger attachment cycles simulating months and years of daily consumer usage.
Step 16
Measures surface hardness and scratch resistance on tempered screen glass, zinc alloy bezels, ceramic back covers, and anti-fingerprint oleophobic coatings.
Step 17
Pneumatic micro-stroke actuators simulate continuous keypresses on rotary crowns, SOS switches, and tactile keys to verify tactile feedback and spring resilience.
Step 18
Centralized aging racks monitor multi-hundred unit batches simultaneously during charge-discharge cycling, standby power drain, and firmware task execution.
Step 19
100% final air-tightness verification conducted on assembled watches before final gift box packaging, ensuring each unit delivered to your warehouse retains factory seal.
