OMEGA SEAMASTER CHRONOGRAPH – 145.006-66 – Black dial – Cal. 321 – 1966

When it comes to hand-wound chronographs, there’s one movement that sits on the throne, wearing the crown, sipping a martini: the legendary Omega Cal. 321. This is the very movement that hitched a ride to the moon and back in the iconic 1969 Speedmaster.

Sure, the Speedmaster steals the spotlight with the ca. 321, but there are other Omegas out there that rock the same movement in slimmer, sleeker cases with dials that are way more interesting. Enter this beauty: the 145.006-66 Seamaster Chronograph.

Why is this piece so special, you ask? Well, let’s break it down:

• A beautiful 38mm C-shaped case. Radial brushing – because this specific reference never had a sunburst brush finished case! Don’t fall for sellers that try to sell you a NOS watch with a sunburst brush, please.
• That pop of orange on the chronograph hand—a little nod to the Speedy Ultraman.
• Radial subdials (only the early batch of 145.006s got these radial stunners).
• A contrasting tachymeter scale for that perfect balance of function and flair.
• Oh, and the lume? All-original tritium with a creamy patina…so gorgeous!

The Cal. 321 only graced this reference for two short years before Omega swapped it out for the Cal. 861 in the 145.016-68.

So yeah, the 145.006-66 isn’t just rare—it’s a full-on treasure chest of 1960s Omega greatness. Seriously, what was in the water at Omega back then? They were just killing it in the ’60s and ’70s, weren’t they?

And honestly, selling a timeless, entry-level classic like this is such a thrill. Vintage watch collecting has to start somewhere, and this piece is a perfect gateway into the world of vintage Omegas.

Fun fact: my own love affair with vintage watches began with some beautiful 1970s Omegas.

Condition? It’s good, with some signs of wear and time. The patina on the hands and indices is dark and creamy, and the movement has been serviced with a 12-month warranty.
