Fifty years ago, U.S. astronauts set foot on the moon, and brought along the Omega Speedmaster, then and forever dubbed the moon watch.

Here is a fine example of this iconic watch.

Check out the inky-black dial with markers taking on a creamy patina.

The stainless steel case looks to have been lightly polished but still retains a decent amount of its original grain.

This is model 145.022-71, carrying the serial of 3100---. Speedmaster experts say this dates it to 1970-1.

The caliber 861 workhorse movement keeps excellent time. The Omega-signed crystal is also in terrific shape.

Comes on a Hodinkee horween strap.
