Swatch Marks Spain’s Total Solar Eclipse With a 24-Hour MoonSwatch Mission to the Sun Solar Eclipse SSX01J100-1

Swatch has created a new version of the Bioceramic MoonSwatch Mission to the Sun for Spain’s total solar eclipse on 12 August 2026. Called Mission to the Sun Solar Eclipse, reference SSX01J100-1, the watch is available only in Spain and only for 24 hours on the day of the eclipse. Online purchases are limited to three watches per person.

A small change with a clear eclipse connection

This is not a completely new MoonSwatch. It uses the familiar Mission to the Sun colour scheme with a bright yellow Bioceramic case, white tachymeter bezel and white rubber strap. The gold-coloured dial has a sun-brushed finish, while white hands and hour markers keep the display easy to read. Orange hands add contrast to the chronograph seconds and the three white subdials.

The important new detail is the black chronograph pusher at two o’clock. The lower pusher remains yellow, so the dark upper button stands out immediately. It represents the Moon moving in front of the Sun during totality. Swatch has changed only one control, but that contrast gives the watch a direct link to the event without covering the dial in extra text or graphics.

The new moon appears on the back

The other change is hidden on the battery cover. Instead of the standard design, this edition carries an image of the new moon. A solar eclipse can happen only during that phase, when the Moon passes between Earth and the Sun. It is a better detail than simply printing the date on the dial because it gives owners something specific to discover when they turn the watch over.

The yellow case uses Swatch Bioceramic, a material made from two-thirds ceramic and one-third bio-sourced material derived from castor oil. The white rubber strap has a VELCRO closure and a matching Bioceramic loop. Like the regular Mission to the Sun, this is a quartz chronograph with 3-bar water resistance. The standard MoonSwatch case format is approximately 42mm wide, 47.3mm from lug to lug and 13.25mm thick.

Only in Spain for one day

The Solar Eclipse costs €280. Swatch is taking online orders exclusively in Spain throughout 12 August. The watch is also offered from the Rolling Planet at two locations in León, first in the city centre from 12:00 to 14:00 and later at the Palacio de Congresos y Exposiciones from 18:00 to 21:00. Selected stores in Bilbao, Ibiza and Valencia also have access to it. Swatch warns that delivery may take longer than usual.

Conclusion

I like the idea more than the size of the changes. The black pusher and new-moon battery cover are clever, but most of the watch remains the regular Mission to the Sun. The €280 price is only €5 higher than the current €275 Spanish price of the standard model. What makes it special is the timing: it can be bought only in Spain on the day a total solar eclipse crosses the country. For a MoonSwatch collector who actually experiences the eclipse, that story may matter more than another completely different colour.
