A beautiful tonneau-shaped Omega with a large 40 mm case, with its impeccable sunburst bezel. It reveals a “double” dial between a sunray silver center, and in relief higher up a “Sandwich” style hour track with black exterior, with the silver finish underneath. A watch that undeniably reminds us of the Omega Dynamic with its screwed ring on the back to hold the bracelet. Here, a NOS timepiece signed Omega.
