Grounded and natural, the Mission to Earthphase suits earthy neutrals — and this MoonSwatch Earthphase strap leans right in. In grey, black and natural tones, whatever material you choose from our MoonSwatch straps echoes the Earthphase complication for a refined, contemporary look on the wrist.

Why choose a MoonSwatch Earthphase strap?
Tuned to an earthy dial
A grey or black MoonSwatch Earthphase strap is the natural match — natural and contemporary. It picks up the dial's grounded, neutral tone rather than competing with it, which keeps the whole watch looking modern and cohesive. The Earthphase is one of the more sophisticated complications in the line-up, so a clean, neutral strap suits it perfectly.
Comfort and durability
Each Omega x Swatch strap is soft, comfortable and built to resist water, sweat and daily wear, holding its colour and shape over time. Neutral greys are forgiving with everyday marks too, so the watch keeps looking sharp with very little effort, and whichever material you pick is made to age gracefully rather than wear out quickly.
Made to fit the MoonSwatch
Cut for the 20mm lug width, this MoonSwatch Earthphase strap seats flush against the Bioceramic case and works on other compatible watches too. The snug fit means no gaps at the lugs and no rattle on the wrist, and the quick-release style lets you change it yourself in a couple of minutes.

Choosing your Omega x Swatch strap material
Every material, one model
Pick a soft MoonSwatch rubber strap for sport, a MoonSwatch leather strap for dressy days, a NATO or canvas for everyday, or steel for a premium finish. Explore the sporty options in our MoonSwatch rubber straps collection.
Earthy colours
Grey, black and natural tones suit the Earthphase best, though every shade is available for this MoonSwatch strap if you'd rather contrast. A tan leather warms the dial, while a charcoal band keeps things sleek and modern, and a stone or sand textile leans into the grounded, natural theme.
Build a small rotation
Keep a grey and a black MoonSwatch strap on hand, and switch with the occasion. The Earthphase's neutral palette is easy to build around, so even a small rotation gives the watch a noticeably different feel, from understated-everyday to quietly dressy, all from a single case.

Fitting and caring for your MoonSwatch strap
Fit it in two minutes
Release the spring bars, seat the new Omega x Swatch strap, click the bars back in and check it's secure — tools are included and no experience is needed.
Easy care
Wipe leather dry, rinse rubber and nylon in warm soapy water, and buff steel with a microfibre cloth to keep your MoonSwatch Earthphase strap looking new. A minute of care now and then is all it takes.
