  • Catalogue Essay

    The present One Hertz Techniek No. 3 perfectly encapsulates the essence of Grönefeld, featuring a beautiful matte galvanised silver dial with a contemporary, playful display of time and a single push-down crown. Launched 2010, this timepiece was numbered 3 of a 30-piece limited line of the world’s first serially produced watch made with an independent deadbeat seconds. Taking centre stage on an elevated bridge, this complication is clearly the most prominent feature of this watch as it occupies most of the dial while the time relegates to a less significant role as indicated in the small sub-register at 2 o’clock.

    Though this feature is not uncommon in horology, the watch community was fascinated by Grönefeld's innovative approach to powering its deadbeat seconds with a unique secondary gear train, which separates the seconds’ independent mainspring barrel from the hours and minutes’. Made entirely in-house, the sapphire caseback exposes a movement that is manually finished to the highest degree with stainless steel bridges throughout and the use of a free-sprung variable inertia balance with Phillips overcoil.

    Consigned by the original owner and preserved in an excellent overall condition, the present Grönefeld titanium wristwatch is a rare and exciting piece, full of potential.
