The four integrated claw lugs gripping the bezel are both the signature design element and a known damage point; inspect all four claw tips carefully under loupe.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| case | Four integrated claw lugs | Four claws symmetrically grip the bezel from case body; all four claw tips are complete and undamaged; claws are polished on face, brushed on sides | Any claw tip that is bent, chipped, or broken; asymmetric claw positions indicating repair; surface finishing inconsistent with factory pattern |
| case | Integrated bracelet attachment | Bracelet integrates directly into the case body through the hidden lug system; no gap between bracelet end links and case; smooth continuous line from case to bracelet | Gap between end links and case suggesting non-original bracelet; end links that move excessively; bracelet attached via standard springbar instead of integrated system |
The Constellation 39mm uses the same four-claw case architecture as the 41mm but scaled to a smaller diameter. Cal. 8600 is Co-Axial Master Chronometer. The claw casting geometry and applied star at 6 o'clock are the visual anchors. Same inspection approach as the 41mm -- claws first.
| movement | Cal. 8600 Co-Axial Master Chronometer | Cal. 8600 Co-Axial Master Chronometer; METAS certification; Omega-signed rotor; exhibition caseback shows Constellation Medallion | Non-Co-Axial escapement; movement without Omega rotor; caseback without Constellation star medallion |
| caseback | Star medallion on caseback | Constellation star medallion in center of caseback; Omega seahorse and text around perimeter; no signs of opening attempts | Missing medallion; pry marks or scratches around caseback edge; caseback that does not seal properly after inspection |
| dial | Constellation dial with Omega logo at 12 | Applied indices with correct Omega font; Omega logo and "Constellation" text correctly positioned; dial color consistent with reference configuration | De Ville or Seamaster dial substituted in Constellation case; incorrect text positioning; applied markers with different finishing than factory |
