QC (Quality Control) photos are images of your specific watch unit, taken by the dealer before shipping. This is your chance to inspect the watch for defects before committing.
You respond with: - GL (Green Light) -- approve and ship - RL (Red Light) -- reject and request a different unit
Most dealers allow 1-2 RLs before issues arise. Don't RL over microscopic details that are invisible at wrist distance (the community calls this "macrophasia").
Priority checklist (high to low):
1. Correct model and factory -- verify you're getting what you ordered 2. Index alignment -- hour markers should be straight and evenly spaced 3. Dial printing -- text should be crisp, logo centered, no smudges 4. Date wheel -- numbers centered in the window, correct font 5. Bezel alignment -- insert should be centered, markings straight 6. Hands -- centered on dial, correct length, no visible scratches 7. SELs (Solid End Links) -- should fit flush against the case, no gaps 8. Cyclops magnification -- should magnify date ~2.5x (Rolex models) 9. Rehaut engraving -- inner ring text should be aligned with indices 10. Timegrapher reading -- rate within +/- 15 s/day, amplitude 250+, beat error < 0.5ms
