OMEGA reintroduces the iconic Calibre 321

If you ask most watch fans to name a famous movement they’d like to see reborn, you’re bound to hear them mention the OMEGA Calibre 321. This robust and elegant chronograph movement has been a favourite since the 1940s and is still highly sought-after by watch collectors around the world. Now, more than 50 years after the last Calibre 321 was produced, OMEGA is bringing the iconic movement back.

Known for its beautifully intricate design, the original Calibre 321 was the first movement ever used in the OMEGA Speedmaster in 1957. It had, in fact, been previously used in some of OMEGA’s other chronographs, namely those in the Seamaster collection. It stands out for its use of a monobloc column-wheel, a feature that is machined from a single piece and which adds technical value. Generally, column-wheel movements require very careful precision in design and build, making them popular with watch collectors.

In addition to its construction, the original Calibre 321 also earned a very notable place in history. It was used in a variety of models including the Speedmaster ST 105.003 (the model first tested and qualified by NASA and worn by astronaut Ed White during the first American spacewalk) and the Speedmaster ST 105.012 (the first watch worn on the moon).

Reintroducing a movement with such an important reputation must therefore be done with the utmost exactness. For the Calibre 321 project, OMEGA utilised a dedicated team of experts who worked efficiently over two years and in total secrecy to bring the movement to life. The small group was composed of researchers, developers and historians, as well as the finest craftsmen and experienced watchmakers. To protect the project’s exclusive details, the team even worked under the codename “Alaska 11”, in line with the names that OMEGA used for its secret Speedmaster designs for NASA in the 1960s and 70s.

Using the 2nd generation Calibre 321 as a reference, the OMEGA team compiled extensive historical research and original plans to reconstruct the movement as accurately as possible. Going even further, they also used “tomography” technology (digital scanning method) to see inside the true Speedmaster ST 105.003 timepiece that astronaut Eugene “Gene” Cernan wore on the moon during the Apollo 17 mission in 1972. Cernan was the last man to walk on the lunar surface and his Speedmaster is now housed at the OMEGA Museum in Bienne. Its Calibre 321 provided the perfect design criteria for OMEGA to follow.

As a result, even the most unique and iconic parts of the Calibre 321 have been reborn in respect to their authentic specifications. The movement wonderfully corresponds to the “moon period” of OMEGA’s history, with a construction that completely respects the designs from the past.

Raynald Aeschlimann, President and CEO of OMEGA, said, “It’s amazing that so many people are passionate about the Calibre 321. We produced the last one in 1968 and fans have never stopped talking about it. That shows how special it is. We’re very excited to finally meet their wishes and have gone to great efforts to bring the movement back.

The new movements will now go into production at OMEGA’s HQ site in Bienne. Uniquely, all aspects of creation will be undertaken within a dedicated Calibre 321 workshop. For each movement, the assembly, as well as the watch head and bracelet assembly will be performed by the same watchmaker. Watch fans can expect more developments and news in the coming months.

BaselWorld 2016: Omega Speedmaster Moonpahse Chronograph Master Chronometer

Omega Speedmaster Master Chronometer Moonphase Gold

Omega Speedmaster Master Chronometer Moonphase Gold


The 2016 Omega Speedmaster Master Chronometer Moonphase has been widely covered, but have you also seen this gold version with white dial? It’s a beast- far from traditional, but strangely appealing!

The Moonphase is powered by Omega’s 9904, a 9300-derived movement with pointer date at 9:00 and moonphase at 6:00 – numbering might be slightly different for this gold version, but no details are out yet. The moonphase is done with great eye for detail.

Our friends over at WatchBase have all the details on these covered.

BaselWorld 2015: any Speedmaster wishes or predictions?

BaselWorld 2015 is around the corner.. Got any wishes and / or predictions?

We think a trio like the above would be great fun : an 1861-based rattrapante in steel, a red dial (not unlike the mythical red dial Rolex Daytona) and a fun ‘First Duck in Space’. What do you think Omega will bring out this year?

On a serious note, we expect one or two new ceramic models and and perhaps one or two nice limited’s – perhaps titanium again? As we’ll be in Basel Sunday ’till Tuesday, we’ll keep you posted!

While we’re at it – Omega, why not create another Speedmaster ’57 Replica using the First Omega in Space case? Or a ‘simple’ reverse panda inspired by the meteorite? The Speedmaster is such a great canvas..
