Tricolour Dial
El Primero A3817 — Tricolour Dial
Undated
White tricolour dial with blue running-seconds accents in the angular A3817 case. European Watch Company’s photographed specimen is on a Gay Frères ladder bracelet and shows creamy luminous patina; the dealer’s originality and unpolished-case descriptions remain attributed assessments.
The dealer dates its specimen circa 1971. Its full execution span is not established. The listing alternates between 36 and 36.5 mm case measurements; these are not imposed as variant-specific dimensions.
