Bart told me that one of the reasons why this type of crown was chosen was that in his early days when working at his father’s clock and watch shop, many customers had come in telling of how they had broken their fingernails when using the crown of their watches. Now, that seems like a little bit of a playful reason and I don’t really believe it, but it’s fun all the same. I personally think that this crown is one of the best features of the watch and really nice to play with.

In the hand, one feels the steady tick from the watch, no doubt due to the amount of power that the dual barrels provide.  On and off the wrist, there is plenty of visual interest to keep you occupied, not least with the dial layout and the bridges on the back. The ticking seconds is fun to have. Sometimes when not thinking, you might, as I often was, be struck by the feeling of looking at a quartz watch. That initial surprise gives way to a realization that this isn’t a quartz, and that reversal is something quite mind-bending.

This One Hertz comes in a variety of different versions, so much so that it’s likely you’ll find your favorite among the collection. Divided into contemporary, classic and open dial collections, I was able to see a representative from each family. The “Dune” in Rose Gold (55,500 Euros) from the classic collection, “Fire” (44,500 Euros) from the contemporary collection and “Nocturne Teckniek” (52,500 Euros) from the open dial collection. All currently available versions come in limited editions of 30 pieces, except “Dune” which is limited to 20 pieces and “Platinum” (in platinum) which is limited to 12 pieces.

I’m told that many of these watches have been spoken for, no doubt due to the immense success of this watch right from the very beginning. If you want one, it might be worth contacting Gronefeld soon, and you just might sneak in to grab one of the last few pieces.

Having seen the One Hertz in person, I am eagerly waiting for what else the Gronefelds will present to the world soon. Given the amount of talent these two brothers have. I am holding my breath as to what it will be. gronefeld.nl
