Ziiiro's Jupiter wristwatch takes minimalism to a new level by eliminating not only the numerals and markers but also the hands, in favor of magnetically-driven beads. Available in four color schemes, the timepiece is named for its resemblance to the planet Jupiter as seen from its poles.

In conventional analog watches, time is displayed by an hour hand and a minute hand that's linked to the movement by a gear train, which means that making a watch without them adds a real air of mystery. The tricky bit is that getting rid of those hands may seem the next logical step in minimalist horology, but it raises the question of how to display the time and how to run the display.

German/Hong Kong watchmakers Ziiiro's solution is to use two tiny steel balls set in grooves in a hydraulically-pressed and sandblast-polished dial set beneath a convex, hardened, mineral crystal and inside a 41-mm, 316L stainless-steel case that provides water resistance to 5 ATM (30 m, 100 ft).

According to Ziiiro, the outer steel ball displays the hours, and the inner one the minutes. These are moved by the Swiss Ronda 502 quartz movement, powered by a Renata 371/SR920SW battery. However, no details of exactly how the magnetic drive works have been released

The Jupiter comes in four color schemes: chrome, rose, black and rose, and black and chrome with a Milanese mesh strap. Each variant sells for US$199.

Pretty and useless. It could be usable as a watch if the face and balls had contrasting colors. But what I'd really like to see is a sweep second ball...

"the outer steel ball displays the hours, and the inner one the minutes." Doubtful as this is that is contrary to all other watches. Also the image of 3:30 has both balls on the outer ring. It's sad when a company can't put out proper information. And why is it so thick?

I love this concept. The reference is more general ‘about what time is it’ rather than the usual crank obsession and delightful to show to others as a kind of living puzzle. Please ignore internet moaners who want sweep second hand and will never buy this or anything else that is not drugs.

I was intrigued with this new design. I love being on the cutting edge of things. It will be awhile to get used to reading that balls of time. I hope to have a ball with this watch. Lol.. No punt intended.

They need to flip it around... so one can feel the time and doensnt have to look at it! :-)

I guess they switched the minute and hour arrangement around because it makes sense to put the ball that travels farther on the smaller ring. Maybe they need that coating used on the new spiffy BMW chain.

Ok, fine.
