Blue Pyramid Dial
El Primero Cover Girl A3818 — Blue Pyramid Dial
Vertically brushed blue dial with a pyramid-shaped fractional-seconds track and contrasting register scales. Wind Vintage’s photographed example is on an orange leather strap; its unpolished condition and sales-award provenance are dealer attributions.
The dealer does not date the individual specimen. No complete production span is assigned to this execution.
Identifying details
- Angular tonneau case
The broad, faceted steel case has the angular tonneau form used by the original A384, A385 and A3818.
- Vertically brushed blue dial
Fine vertical brushing runs across the blue dial around contrasting subsidiary-register tracks.
- Pyramid fractional-seconds track
The dial’s distinctive pointed fractional-seconds markings create the collector-described pyramid or shark-tooth pattern.
