The Omega Speedmaster Professional Moonwatch reference 311.32.40.30.01.001, or "First Omega in Space," is a notable variant within the Speedmaster line. It commemorates the CK2998 that Wally Schirra, the NASA Aviator wore during the 1962 Mercury-Atlas 8 mission.

This particular model features a 39.7mm stainless steel case, smaller than the standard modern Moonwatch, and uses "Alpha" hands. The black dial presents the classic chronograph layout, and the black tachymetre bezel remains a standard feature.

Technically, it utilizes the manual-winding Omega caliber 1861 movement. The crystal is sapphire. The watch is presented on its original brown leather strap.

On the wrist, the 39.7mm case size is comfortable for a range of wrist sizes. I personally find the smaller case and "flat" link styled bracelet contribute to a more vintage 70s feel. The watch sits well and is easy to read.

As we all know, the Speedmaster's history is significant. This "First Omega in Space" reference, with its design cues to the early NASA certified Speedmasters, has its own appeal. The 2012 date indicates a relatively recent example, and the inclusion of the original box and certificate adds to its completeness.

In terms of market position, this reference is sought after by collectors who appreciate the vintage design elements and the connection to the early space missions. It's a solid, functional chronograph with a clear historical link.

This Omega Speedmaster Professional "First Omega in Space" is a remarkable timepiece that bridges the past and present. It's a watch that not only tells time but also tells a story, a story of adventure, innovation, and human achievement. It's a worthy addition to any collection, a conversation starter, and a piece that will undoubtedly be cherished for generations.
