MZF 4131 迪通拿青金石钻圈包金

GL candidate · automated visual QC

S005 · Camera geometry corrected. Image rotated approximately 1.5° clockwise at the dial centre; perspective and unequal image scaling normalized to a circular dial reference using detected printed tick centres. Recentered and resampled to 1900 × 1900 pixels. No correction for crystal refraction or raised bezel/hand geometry. Extended rays are visual dial references only; they do not correct or measure the raised bezel.

RECOMMENDATION

Visible QC is acceptable, with a slight apparent 10 o’clock gem-marker lean noted in S005 and S006 but no compelling mounting defect established. Overall dial placement, hands and visible finish show no major issue.

Dial placement and local marker straightness

The dial layout appears coherent. A slight apparent lean at the 10 o’clock blue gem marker recurs in S005 and S006. Its reflective facets and metal setting show different edge directions. This is a minor visible concern, not a confirmed mounting defect.

S005 S006

Coronet, printing and hands

The 12 o’clock feature is a coronet. The central chronograph hand crosses it and portions of the printing. Visible hands show no obvious damage; obscured characters cannot be fully inspected. The review describing a leaned luminous bar at 12 is not supported by the pixels.

Date

No date aperture is visible in this three-subdial layout. Date centering and changeover are not applicable to the visible configuration.

S005 S006

Raised gem bezel

The visible blue bezel stones form a continuous surround. Bright and dark sectors change markedly between views, particularly across the upper bezel. Reflections and tilted views do not establish a displaced or missing stone.

S005 S006 S007

Visible finish

Visible case, jeweled lugs and bracelet show no compelling damage. Bracelet film, stickers and reflections conceal portions of the finish. Exposed surfaces appear acceptable; covered surface condition remains unverified.

Timegrapher snapshot

Rate +4 s/day; Amplitude 286 °; Beat error 0.1 ms; Lift angle 52 °; Beat rate 28800 bph Displayed amplitude depends on the selected lift angle; the correct setting for the installed movement is not verified. Winding, stabilization, position and recording duration are unknown. Two transcriptions of one source are not independent timing measurements.

S024

Red ring: printed dial-track reference. Red dashed rays continue the dial positions across the bezel for visual comparison only; they do not correct, measure or set a tolerance for the raised bezel or cyclops. Cyan crosshairs mark the dial’s cardinal axes. Green lines show released luminous-insert axes, and amber outlines show candidate reflective edges. Positive angles are clockwise; negative angles counterclockwise. Sensitivity ranges are not confidence intervals. Native close-ups preserve the source view.
