Lab Testing vs Real-World Wear Performance
This page explains what QC tests can prove. It also explains what daily wear can change.
Transparency rule: We only state what we can verify.
We avoid exaggerated claims and hidden limits.
Why This Comparison Matters
Lab-style checks confirm basic stability before shipping. Real-world wear adds variables we cannot fully control.
The goal is clear expectations and evidence-based decisions. QC media supports your confirmation step.
What “Lab Testing” Means in Our QC
Our QC includes inspection and functional checks. It follows a fixed process from inspection to shipment.
QC Core Steps
- Factory initial inspection.
- Inbound re-check after stock preparation.
- Movement power test.
- Timekeeping deviation test.
- Appearance checks for case, dial, and alignment.
- Bracelet and clasp structure checks.
- Lume check, when applicable.
- QC photos or video capture.
- Customer confirmation before shipping.
What “Real-World Wear” Can Change
Real wear depends on habits and environment. Some results vary even with the same movement type.
Wear Variables We Disclose
- Mechanical deviation is normal.
- Deviation relates to structure and wearing habits.
- Coating life depends on friction and wearing style.
- Lume brightness and duration can vary by batch.
- Water use beyond limits increases ingress risk.
Lab vs Wear: What Each Side Can Prove
QC is proof for the shipped watch condition. Wear performance is a usage outcome, not a promise.
| QC / Lab-Style Checks | Real-World Wear Outcomes |
|---|---|
| Timekeeping deviation check Screenshots may be provided as evidence. | Deviation changes with wearing habits. Mechanical deviation remains normal. |
| Power reserve behavior check Confirms basic energy performance at QC time. | Results vary with winding habits and daily movement. |
| Winding efficiency check Confirms stable winding behavior in QC. | Wear frequency affects how often you need winding. |
| Alignment checks Date, index, and hands are inspected. | Impacts your daily reading comfort. Misalignment risk is disclosed if found. |
| Material & component safety checks Anti-allergy metal tests and plating corrosion tests. | Skin response depends on individual sensitivity. Wear conditions can still vary. |
| Water-use limits disclosure Optional enhanced sealing test is paid and separate. | Daily splashes only are recommended. Avoid showers, steam, swimming, seawater, and saunas. |
QC Evidence You Receive
QC media is based on the exact watch being shipped. We do not use renders or modified QC images.
QC Photo Coverage
- Front, back, clasp, and bracelet sides.
- Lume photo when applicable.
QC Video When Feasible
- One-take appearance video.
- Timekeeping and balance running display.
When a Watch Is Intercepted in QC
QC interception protects stable batches. It also reduces obvious defect delivery.
Typical Interception Items
- Severe index misalignment.
- Obvious date alignment problems.
- Deep case scratches.
- Abnormal movement power behavior.
Responsibility Boundaries
We handle QC issues, shipping damage, and wrong items. Customer-side risks include misuse and water beyond limits.
Examples of Customer-Side Risk
- Water ingress from use beyond recommended limits.
- Problems caused by self-disassembly.
- Damage caused by human misuse.
Customer right: You can request clarification and extra QC shots.
Shipment happens after your QC confirmation.
After-Sales Support for Wear-Related Issues
Warranty covers mechanical structure faults and movement issues. Non-human functional faults are included.
Lifetime maintenance support is available with transparent pricing. It includes lubrication and oil replacement services.
Maintenance Support Items
- Movement maintenance service.
- Timekeeping adjustment.
- Full watch cleaning.
- Professional lubrication and oil replacement.
How to Use This Guide
Use QC evidence to confirm the shipped condition. Use disclosures to set daily wear expectations.
If you need help, ask for usage assistance. We support time and date adjustment guidance.
