Authentication Notes

Dial

CriticalProbable

Mark I–V dial detail is frequently faked

Coronet shape, 'Explorer II' font and minute-track vary by documented Mark; service and redial dials are common. Cross-check dial mark against the production window and hand set.

Hands

HighHigh confidence

Fixed, non-independent 24h hand

On the 1655 the orange arrow is NOT independently adjustable (cal. 1575) — it always reads 24h off the main time. Independently settable 24h hands begin with the 16550 (cal. 3085).

Lume

HighHigh confidence

Tritium-era designations

Period-correct 'SWISS', 'T SWISS T' or 'SWISS - T<25' at 6 o'clock; a LumiNova 'SWISS MADE' dial on a 1655 is wrong.
