One Hertz 43mm

TYPE: Watches
DESIGNER: Grönefeld
ITEM #: one-hertz


The Grönefeld One Hertz is the world's first and only series wristwatch with independent dead seconds. It features a beautiful solid silver dial and an entirely in-house developed movement with stainless steel bridges and exceptional fine finishing.

Dead seconds is where the second hand advances in full steps of one second instead of the usual smooth sweeping action of mechanical seconds.

With the One Hertz, Bart and Tim Grönefeld have resurrected this long-neglected horological complication and re-positioned it on the pedestal of high precision.
