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.
Known issues in the market
Claw tip damage from prying during unauthorized caseback attempts; the claws are thin and the tips break or deform under tool pressure.
Bezel insert replacement with non-original; the fluted bezel on this reference has specific geometry and finish.
Cal. 8600 replaced with non-METAS movement; METAS certification is a key feature of this reference.

Missing medallion; pry marks or scratches around caseback edge; caseback that does not seal properly after inspection

Common legitimate replacements
Claw tips are the most commonly damaged and repaired element; any claw repair should be disclosed and reduces value.
Integrated bracelets are specific to the Constellation and non-original replacements are immediately visible at the end links.
Caseback star medallion is a replaceable component during service; verify medallion is present and correctly installed.
Expert resources: OmegaForums.net Constellation technical threads. Omega Museum serial database. Claw inspection guide: use a 10x loupe and bright light to check all four claw tips for completeness. Integrated bracelet end-link gap test is a reliable field check.
