MoonSwatch Castor: the new €385 Omega x Swatch model celebrates a strange moon

The Omega x Swatch collaboration takes a step aside with a piece that shakes up codes, inspired by a “moon” like no other. Fans of accessible chronographs will see it as a playground, while the curious will seek out the meaning of an “Earthphase”. And so the conversation resumes on a model that blends celestial poetry with everyday use.

A new milestone for Omega x Swatch

The new Mission to Earthphase, codenamed “Castor”, follows in the footsteps of the releases that punctuate the year. According to available information, this variant emphasizes a playful reading of the cycles, with a nod to a ” very strange moon “. What’s more, the advertised retail price is in the region of €385, in line with a carefully thought-out pricing strategy. The message remains clear: make thematic watchmaking more visible, without denying the Speedmaster DNA.

Aesthetically, the watch takes up the sporty look and bioceramic material so dear to the line. The chronograph, with its quartz movement, displays the phases of the Moon and Earth on a dedicated disc. In this way, the watch tells the story of a cycle on the wrist, appealing to collectors and beyond. On the other hand, every color detail may vary according to the edition, so it’s worth checking in-store.

Access to these models remains restricted. Swatch’s physical points of sale often manage distribution, which involves planned travel. As a result, availability can change rapidly from city to city and day to day. Omega x Swatch maintains this rhythm, between relative rarity and wide distribution.

“A fun watch that puts astronomy back on the wrist.”

Reading an Earthphase is like following the light of our planet, mirroring the Moon. In this way, the thematic disc completes the poetic function seen on other variants.

Why Omega x Swatch still fascinates

Since 2022, the MoonSwatch wave has been capturing a broad public, curious about design and storytelling. The recipe is a blend of Speedmaster codes and affordable materials. The result is a space story worn on the wrist at a moderate cost. Omega x Swatch has thus created a recurring rendezvous with precise themes.

The “phase” complication has established itself as a recent, playful signature. It invites you to look up, then link your daily life to the celestial cycles. What’s more, the display is intuitive and easy to read. Omega x Swatch knows how to tell a story without technical jargon.

The Castor variant adds a narrative layer. It refers to an identifiable celestial inspiration, while retaining a legible dial. In this way, the model remains portable, even for a first passion purchase. The discreet name does not overshadow functionality.

Castor bias

The “Earthphase” orientation adds an educational dimension to the watch. It follows the Earth’s light as a graphic red thread. In short, it’s an observation game that lives to the rhythm of the calendar. Omega x Swatch turns this detail into a daily conversation.

The theme reminds us that the Moon and Earth share related cycles. However, the wearer doesn’t have to memorize complex values: the disc does the job. What’s more, a well-placed visual cue makes for immediate reading. The experience remains coherent, without overload.

Smart buying: where and when

Before travelling, it’s best to check local availability and any queuing arrangements. This way, you can avoid an empty visit on busy days. What’s more, thinking about accessories helps: a second bracelet changes the style in a minute. Omega x Swatch is most enjoyable when the shopping experience is seamless.
