Omega Moonwatch Co-Axial Master Chronometer Moonphase Watch
The Moonwatch Moonphase watch is one of Omega’s most celebrated time offerings. The Omega Moonphase watch was a part of all six lunar missions. Here is a timepiece that took the spirit of exploration a step further. More so, the new Omega Moonwatch Moonphase watch features two infinitely small yet photo-realistic moons to add to its uniqueness.
Moreover, this 44.25 mm model comes with a blue sun-brushed dial and rhodium-plated indexes. When it is 6 o'clock, you see the precise Moonphase manifestation. It comes in the form of a metallic crystal disc micro-structured to achieve a high-resolution impression of the moon.
In addition, there is a stainless steel case complemented by a blue ceramic bezel ring. Also, the bezel ring comes with a Liquidmetal™ tachymeter scale. These features appear on a black or blue leather strap with a polished-brushed foldover clasp. Lastly, powering the watch is the Omega Co-Axial Master Chronometer 9904. That’s one movement officially certified by METAS.
Suffice to say; the Omega Moonphase watch is all-round excellence! Below is an outline of the technical specifications of this Omega's timepiece in summary.
In 2017, the legendary Omega Moonwatch celebrated its 60th anniversary after initially launching in 1957. After a decade after its launch in 1957, it earned the nickname the “moonwatch.” Every timepiece lover understands that the Moonwatch Moonphase watch by Swiss Omega was the chosen one. That reality comes after endlessly drilling the fact into their evidently excited mind.
The Moonphase watch got selected by the American NASA to be the official watch worn by Apollo mission astronauts. Later on, it made it to the moon and it did so a few times. In particular, 2019 will be the 50th anniversary of Apollo 11. Meanwhile, we stay hopeful that Omega gives us something thrilling in place of that.
However, before we digress, our focus here is on the Omega Moonwatch Co-Axial Master Chronometer Moonphase watch debuted in 2016.
Meanwhile, at the time, Omega couldn’t decide how it will truly be a part of modern spaceflight actions. That’s how the brand sought to ensure it stayed relevant in its theme in the future. Although, one thing that truly keeps the Moonphase watch up there isn’t only a connection to the historic moon missions or NASA. In all honesty, what works for this watch is its winning design.
Besides, the Moonwatch Moonphase comes in editions that take on so many styles and several variants. The varieties are so broad that even highly trained specialists have difficulties keeping track of all the renditions of this watch.
Again, there have been other Omega Speedmaster editions with moonphase indicators and chronographs before now. Additionally, one of them is still available for sale, with a nearly indistinguishable case. However, it features a distinct dial layout and movement.
In fact, writing about the Omega Master Chronometer Moonphase after seeing it hands-on after Baselworld 2016, there is that issue of the right name to call it. Having a ten-word name and a tricky combination of special specs, this otherwise very lovely Omega watch requires a lot of special attention. That is the only way it can stand out from the crowd.
Now, there is a right subdial with having hands where one measured hours and the other minutes. Again, the 9300 family of in-house automatic Co-Axial chronograph movements got replaced with the 9900 series family of movements. With this swap, the watchmaker introduces some developments such as non-ferrous metal parts for key elements. That made the watch more or less completely resistant to magnetic fields. Here is part of what “Master Chronometer” means. Also, it is part of the rather special METAS certification that every Master Chronometer enjoys.

Introducing the Omega Moonphase Watch

A Brief History of the Omega Moonwatch Moonphase Watch
Following the moon missions, the onetime racing and pilot-themed watch became the timepiece related to the moon. This wristwatch also got associated with all things pertained to astronauts. Here is an impression and trend that continues to endure today.
Omega Watches and Product Naming
In addition, Omega Speedmaster product naming conventions don’t help much. Most times, they get confusing and similar to one another. At other times, they are abstract and hard to recall. A good example is the official name of this timepiece according to the Omega website. The website states it to be the “Omega Speedmaster Moonwatch Omega Co-Axial Master Chronometer Moonphase Chronograph 44.25 MM.” Meanwhile, that doesn’t even contain the reference number. More so, the name actually includes “Omega” in it twice. One reason we can give for this is that Omega has so many similarly-themed time offerings. In the real sense, the timepieces themselves come quite different. They are different enough for it to get very challenging to describe them.

Omega: A Brand with Several Options
The Movements: Another Omega Variety
Many years ago, in 2011, the Omega Moonphase watch got modern as Omega launched the first new generation models. The spice in this launch was the introduction of the in-house-made caliber 9300 family movements. With these new movements, the brand got rid of the chronograph’s three-subdial layout. Now, the brand turned to a two-subdial design instead.
