The Story Behind the Swatch x OMEGA MoonSwatch Mission to EarthPhase

The Mission to EarthPhase is one of the latest chapters in the Swatch x OMEGA MoonSwatch story – a collaboration that redefined the modern collector market. Released as a nod to the Speedmaster’s heritage and Earth’s tranquil tones, it carries the reference SO33M700, crafted in Swatch’s signature bioceramic case. Its design draws inspiration from the Earth as seen from space – grey and blue tones that represent the balance between day and night. The EarthPhase is not just a visual statement – it’s an homage to the Speedmaster’s role in exploration, capturing the harmony between OMEGA’s technical precision and Swatch’s playful creativity.

Why Collectors Love the EarthPhase

Collectors are drawn to the EarthPhase for its subtle colourway and connection to the legendary Speedmaster Professional – the “Moonwatch” approved by NASA in 1965. While earlier MoonSwatch models like the Mission to Neptune and Mission to Jupiter lean on bold contrast, the EarthPhase introduces a calmer palette – a watch that feels as sophisticated as it does adventurous. Its MoonPhase sub-dial adds a refined touch for those who appreciate horological detail in a playful form. At MGBWATCHES, we see this model becoming a future classic – a MoonSwatch that bridges the gap between casual collectors and serious enthusiasts.

Best Straps for the Swatch x OMEGA Mission to EarthPhase

1. Rubber Woven Straps – Modern Durability with Collector Appeal

Our rubber woven straps are crafted for daily wear. They offer a lightweight, vented design that keeps the wrist cool and comfortable. For the EarthPhase’s blue-grey finish, we recommend our Grey & White Rubber Woven Strap or the Super Blue MoonPhase edition, both colour-matched to its bioceramic case. Collectors value these for their secure fit and long-term resilience. Discover compatible options in our MoonSwatch Straps Collection.

2. Premium NATO Straps – Inspired by Speedmaster Heritage

The NATO strap is the unsung hero of OMEGA history. Originally designed for military function, it has become a collector favourite for MoonSwatch models. Our Bond-style Black & Grey NATO works beautifully with the EarthPhase, offering a textured contrast that highlights its case colour without overpowering it. It’s a nod to heritage while remaining modern and lightweight.

3. Leather and Suede Straps – A Refined Alternative

For those who prefer a touch of classic elegance, our calfskin and suede straps add warmth and texture to the EarthPhase. Beige and grey tones soften the watch’s profile and make it more versatile for everyday wear. These straps also age beautifully – a feature collectors appreciate as each piece develops a unique patina over time.

How to Change a Strap on the EarthPhase

Swatch and OMEGA designed the MoonSwatch series with simple spring bar lugs for easy strap changes. To replace your strap:

1. Use a spring bar tool or fine pin to release the existing bar.
2. Align the new strap with the lugs and compress the spring bar until it snaps into place.
3. Gently tug each side to check stability.

Our rubber woven and NATO straps fit directly without adaptors, ensuring a clean fit for the EarthPhase and other MoonSwatch models. Need a visual guide? See our How to Change Your MoonSwatch Strap blog.

How to Set the EarthPhase

While the EarthPhase retains the MoonSwatch chronograph layout, its MoonPhase indicator adds an extra touch. To set it accurately:

1. Pull the crown to the second position.
2. Rotate until the date and MoonPhase align to the current lunar day.
3. Push the crown back in and restart the chronograph if used.

This function mirrors OMEGA’s Speedmaster MoonPhase design but simplified for the Swatch movement.

EarthPhase vs Mission to the Moon – What’s the Difference?

The Mission to the Moon remains closest to the Speedmaster heritage, featuring a dark grey bioceramic case and traditional chronograph. The EarthPhase, however, adds new visual character and functionality through its moonphase sub-dial and refined colour contrast. It’s lighter in tone, more playful in concept, and sits comfortably as a companion piece for those who already own earlier missions.

Why the EarthPhase Matters

The EarthPhase marks the evolution of the MoonSwatch line – from simple colour-coded tributes to functional extensions of the Speedmaster legacy. It balances Swatch’s accessible design with OMEGA’s space-born storytelling. Owning one is owning a piece of that shared history – and personalising it with the right strap is what makes it uniquely yours.
