Marketplace Listing Audit Checklist
Critical questions to ask before buying budget watch hand tool sets online.
Screwdriver Tip Sizing
Are individual blade widths explicitly documented in millimeters, or vaguely labeled as assorted? Screw slots require sub-millimeter match to avoid burred screwheads.
Steel Alloy Disclosures
Does the seller name a specific steel grade or merely state high carbon? Unspecified budget steels are prone to chipping or deformation under moderate torque.
Magnetic Characteristics
Are tips advertised as magnetic? Magnetic drivers can inadvertently magnetize hairsprings in mechanical calibers and cause severe timing drift.
