Dial
Tsikolia-logo counterweight on the central seconds hand
The central seconds hand carries the Tsikolia logo as its counterweight — a deliberate brand signature. Absence, or a generic counterweight, is inconsistent with a genuine Seven chronograph.
Movement
Swiss Ronda 5040.B quartz chronograph
The Seven chronograph uses the Ronda 5040.B (Swiss quartz, small-seconds + chronograph). A mechanical movement or a different quartz caliber in a purported Seven chronograph is a red flag.
Serial
Limited-edition number engraved on the caseback
Seven chronographs are limited editions with the edition number engraved on the caseback. Verify the number against brand documentation; a missing or non-conforming engraving warrants scrutiny.
