Ziiiro’s Gravity and Mercury, watches that function without any of the markings of standard analog timepieces, instead using a continuously rotating combination of two rings to make temporal distinctions…..See Details.
The tip of the inner ring represents the hour, while the tip of the outer ring denotes minutes, and a fading gradient tracks the passage of time. Mercury, which touts a stainless steel band, comes in four different color schemes, while Gravity boasts a patent pending bracelet strap, available in six colors. Both watches also feature pop-out faces, allowing for a variety of Swatch watch-style face-band pairings. Prices range from $130 to $175.
