The minimal Gravity watch is the first design by new Hong Kong watch brand Ziiiro. Without typical hands or markings, the Gravity watch uses two rings that resemble rotating comets to indicate the time. The fatter, inner ring marks the hours while the narrower outer ring shows the minutes. The rubber strap does not have a fastener but instead wraps around the wearer’s wrist. It can be made tighter or looser by bending the strap’s stainless steel core.
