Review & Comparison Policy
Criteria, evaluation boundaries, and evidence limitations for tool assessments.
Evidence Limitations
Pin & Caliper uses a specification-research methodology. We do not operate a metallurgical testing laboratory, perform destructive stress tests, or conduct Rockwell hardness measurements. All ratings and comparisons reflect systematic auditing of seller-reported specifications, part compatibility constraints, and reported manufacturing tolerances.
Comparative Evaluation Criteria
| Tool Class | Key Audited Metrics | Risk Factor Assessed |
|---|---|---|
| Case Openers | Pin arrangement (two vs three point), jaw diameter range (mm), bit shapes | Caseback slippage and lug gouging |
| Screwdrivers | Blade widths (0.6mm to 2.0mm), documented alloy, magnetic vs non-magnetic | Cam-out damage to screw heads, movement magnetization |
| Pin Pushers & Forks | Fork tip width (standard vs fine 1.0mm/1.2mm), replaceable pin stems | Pin bending, scratched polished bracelet flanks |
| Holders & Vises | Jaw padding material (nylon vs bare metal), maximum clamp diameter | Crush damage or scuffs to watch bezels and cases |
No Guarantees on Maintenance Outcomes
Watch modifications and repairs carry inherent risk. Tool recommendations indicate structural compatibility based on documentation; they do not guarantee that a repair will succeed without user error or cosmetic damage. Readers are urged to tape lugs, check fastener slots with magnification, and never force a poorly fitted tool.
