Community + OSINT signals haven’t landed for this reference yet. We don’t publish a rating against zero signal — the number would mean nothing. Editorial body + caliber + market value still surface above; ratings appear once the signal corpus does.
Column wheel visible through caseback is the definitive movement check; sub-dial layout is case-specific.
Known issues in the market
Incorrectly positioned sub-dials indicate a wrong dial for this case; Marine Chronograph case is engineered for a specific sub-register layout.
Pusher play around apertures indicates wear; machined tolerances on Marine Chronograph are tight.

The Marine Chronograph 43mm uses the in-house Cal. UN-76 column-wheel chronograph with silicon components. The column-wheel mechanism is visible through some movement orientations and the pusher action should be crisp. The 18k gold rotor mass is a specific tell for the genuine UN-76.

MEDIUM
Marine Chronograph replicas exist but the 18k gold rotor mass and silicon components are movement-level tells that distinguish genuine examples.
All-steel rotor visible through caseback instead of the gold-mass rotor of Cal. UN-76
Silicon escape components absent from the movement
Pusher action that lacks the crisp column-wheel click character

Chronograph pushers
Original: Screw-down chronograph pushers sealed for water resistance. The pushers must be screwed down (unlocked) before activating. Activation should produce a crisp, positive click consistent with a column-wheel mechanism.
Replacement tells
Pushers that do not screw down (non-sealed replacement pushers)
Pusher action that is mushy or lacks positive click (indicates worn or non-column-wheel mechanism)
Non-functional chronograph activation on either pusher
Movement rotor via caseback
Original: Exhibition caseback displaying Cal. UN-76. The rotor carries an 18k gold mass -- this appears as a distinctly warmer, gold-colored segment on the rotor arc compared to the steel movement components.
Replacement tells
Rotor without a gold-colored mass -- an all-steel rotor indicates movement replacement or non-original rotor
Movement layout inconsistent with Cal. UN-76 known bridge geometry
Silicon escape components absent (flat dark non-reflective components should be visible)
Anchor crown
Original: Screw-down crown with anchor logo on the end face. The crown screws down for 100m water resistance.
Replacement tells
Crown without anchor logo
Crown that does not screw down to seal
Crown with thread damage preventing proper seating

Cal. UN-76 is a column-wheel chronograph. The column wheel is visible under magnification through the caseback in some orientations. A column-wheel mechanism produces a notably crisper pusher action than a cam-actuated chronograph.
The 18k gold rotor mass is a specific production detail of the UN-76. Its absence on a stated genuine movement confirms a movement swap.
Silicon escape components in Cal. UN-76 should appear as flat, dark, non-reflective elements. Conventional metal components in their place indicate a non-original escapement.
Power reserve is approximately 48 hours. A Marine Chronograph stopping before 40 hours when fully wound warrants service.
