Omega Seamaster Ref. 145.006-66 – Calibre 321 Chronograph

A rare gem in Omega’s chronograph lineage, the Omega Seamaster Ref. 145.006-66 is powered by the legendary Calibre 321 — the same movement found in early Speedmasters worn in space. This 1966 model captures the golden era of Omega tool watches, blending functionality with clean, architectural design.

At the heart of this timepiece lies the revered Calibre 321 manual wind movement, known for its column-wheel architecture and exceptional horological pedigree. Housed in a robust 38mm stainless steel case, it offers a bold yet classic wrist presence — larger than most of its contemporaries and remarkably wearable today.

The black dial is framed by a sharp silver tachymetre scale and accented by a striking red chronograph seconds hand, giving this piece both vintage charm and sporty edge. The original Omega-logo signed acrylic crystal is still in place, a desirable feature that adds character and authenticity.

It’s paired with a high-quality black leather strap, creating a sophisticated contrast and ensuring all-day comfort.

🔑 Key Features:

  • Year: 1966

  • Dial: Black dial with silver tachymetre scale and red chronograph seconds hand
