First, Set the Right Expectation

Time drift is not always a defect. It is often a normal outcome of daily conditions.

• Deviation relates to movement behavior and usage conditions.
• Stability matters more than chasing perfect numbers.
• Long-term ownership may require periodic adjustment.

What Changes Over Time

Lubrication and Long-Term Care

Long-term care includes cleaning, lubrication, and oil service. It also includes timekeeping adjustment when needed.

• Maintenance services include professional lubrication and oil service.
• Timekeeping adjustment is part of long-term support.
• Service exists to keep use stable over time.

Daily Wear Patterns and Power Behavior

Real-life use affects how a mechanical watch behaves. Wearing frequency and habits can change perceived stability.

• Movement testing includes power behavior evaluation.
• Abnormal power behavior is an interception item during QC.
• Daily habits can affect long-term consistency.

Environmental Factors That Can Shift Stability

Storage and daily environment matter. Some risks are avoidable with basic awareness.

Moisture Risk

• Warehouse handling emphasizes humidity control to prevent damp exposure.
• Stable storage conditions support long-term reliability.

Magnetization Risk

• Handling avoids strong-magnet areas to reduce magnetization risk.
• Basic prevention helps protect mechanical behavior over time.

This section stays practical. It does not describe internal components or measurements.

What QC Can Confirm, and What It Cannot “Freeze Forever”

QC reduces uncertainty before shipment. It does not prevent natural changes from future use.

• QC includes timekeeping deviation testing.
• QC includes power behavior testing.
• QC includes appearance and alignment checks.
• QC photos and videos are provided for customer confirmation.
• Shipping happens only after customer approval.

When Drift Becomes a “Support” Topic

Support relies on clear proof and defined handling. This helps reduce misunderstandings.

Help and Knowledge Support

• Assistance includes timekeeping deviation explanations.
• Guidance can include time and date adjustment support.
• Users can request help when questions appear.

Evidence Requirements for Functional Issues

• High-resolution photos may be required.
• Problem videos may be required for functional claims.
• Full unboxing video is required for missing-items claims.

Summary

• Mechanical watches have a normal deviation range.
• Timekeeping can change with use, conditions, and long-term care needs.
• QC confirms stability before shipping, with customer approval.
• Long-term support includes adjustment and maintenance services.
• Prevention of moisture and magnetization helps reduce avoidable risks.
