What happens when the most wanted MoonSwatch in the collection swaps its white velcro for genuine ostrich leather? You get the Special Edition - Swatch x Omega Bioceramic Moonswatch Mission to Ostrich Mars, reference SO33R100C, released only in select Swatch boutiques and, ever since, living more on wish lists than in display cases.
The Special Edition - Swatch x Omega Bioceramic Moonswatch Mission to Ostrich Mars is the special version of the Mars MoonSwatch: the same red 42 mm Bioceramic watch with a quartz chronograph, but with an original ostrich leather strap and reference SO33R100C. Its selective distribution through specific boutiques is what makes it a collector's piece.
What is the MoonSwatch Mission to Mars Ostrich SO33R100C
Let's start with what we know: the original Mission to Mars (SO33R100) landed in March 2022 with a deep red Bioceramic case and a white dial, bezel and strap, a direct nod to the Speedmaster "Alaska Project". Inside beats a quartz chronograph with Super-LumiNova-treated hands and 3 bar water resistance.
The Ostrich version doesn't touch any of that. The watch is identical; what changes is the strap and, with it, the whole character of the piece. The letter C at the end of the reference is the detail collectors use to tell an SO33R100C from a regular SO33R100 at a glance in any listing.
What the MoonSwatch ostrich leather strap is like
The ostrich straps in this collection are made in France and each one carries the characteristic follicle marks of the leather, those raised dots that mean no two pieces are exactly alike. It feels soft and flexible from day one, without the break-in period typical of other leathers.
On the inside you'll find the heat-embossed Omega x Swatch signature, a discreet finish you only see when you take the watch off. It's the kind of detail that gets these editions shared so much on forums and social media: the contrast between the technical plastic of the case and a hand-worked exotic leather.
Key points of this special edition
- Genuine ostrich leather strap instead of the white velcro of the standard model.
- Reference SO33R100C, the suffix that identifies the Ostrich versions.
- 42 mm Bioceramic case in Mars red, with a white dial and bezel.
- Quartz chronograph, lightweight and no winding needed.
- Selective distribution: it launched in specific Swatch boutiques, not as a permanent catalog piece.
Differences between the regular MoonSwatch Mission to Mars and the Ostrich
The question comes up in every forum thread. The short answer: the watch is the same, the strap and the edition are not. Same case, same dial, same movement, same chronograph readout.
The real difference is in the positioning. The SO33R100 was sold in Swatch stores around the world; the Ostrich variants debuted at very specific openings and flagships (the most talked-about was the opening of the Swatch space at Harvey Nichols in London) with eleven reinterpreted models, each with a strap matching its case color. That scarcity from the start is what sustains its status today.
How does the 42 mm MoonSwatch wear on the wrist?
42 mm sounds big on paper, then it isn't. The case shape inherited from the Speedmaster spreads the volume well and Bioceramic weighs very little, so it's comfortable to wear all day even on medium wrists: it's one of the things daily wearers mention most.
There's one honest caveat about the ostrich strap worth sharing: users describe it as soft and flexible from the start, although some collectors say it adds a bit more body to the overall feel compared with the original velcro. If you're coming from a textile strap, you'll notice the watch a touch more on your wrist.
Styling ideas
- A neutral total look (off-white, beige, grey) so the Mars red is the only accent.
- Raw denim and a white tee: the easiest combo and the one that looks best in photos.
- With a dark blazer, taking advantage of the fact that the ostrich leather makes it far dressier than any velcro MoonSwatch.
- As a contrast piece over technical wear: nylon, military tones, white sneakers.
Why the SO33R100C is a collector's piece
For a good part of the community, Mars was already the best-executed MoonSwatch in the whole collection thanks to that bold red/white contrast. Add an exotic strap made in France and a distribution that was never global, and you have the full equation.
This isn't a watch that gets restocked in just any store: that's why people who want it search for it by exact reference. You can check availability and all the details of the Special Edition - Swatch x Omega Bioceramic Moonswatch Mission to Ostrich Mars before you decide.
