The Grönefeld One Hertz is a unique watch because it is the only series wristwatch with “independent” dead seconds. Dead seconds means that the seconds hand moves in one-second jumps, like we’re all used to seeing on a quartz watch. This is desirable because it makes it easier to time things to the nearest second. It is “independent” because instead of being run off of a constant force device, like on the F.P. Journe tourbillon, its dead seconds hand is powered by a secondary gear train that is independent of the hour and minute indications and driven by its own barrel.
To show off the one hertz motion of the seconds hand, the seconds subdial is large and prominently displayed on the dial. And the fit and finish of the dial is impeccable. The back side is another treat because the in-house movement has cool grained-steel bridges that look fantastic. And we’re not the only ones that think so…the One Hertz was voted the Watch of the Year by the readers of Timezone.com!
This particular watch here is a special version in a titanium case with a mesmerizing blue dial. Simply put, an amazing version of an amazing watch.
The watches from Grönefeld aren’t just desirable because of their interesting family tale. These guys are very talented watchmakers! Before starting their own company, the brothers held senior positions at other firms, including the renowned Renaud et Papi. Though the company is quite young, they’ve already earned a lot of acclaim and awards for their watches, including 2 prizes at the Grand Prix d'Horlogerie de Genève.
