Grönefeld One Hertz
Hertz So Good

In the world of haute horlogerie, complications are everything. Brands want to produce them as a sign of prowess; collectors want to possess them for, well, collecting's sake. The tourbillons, perpetual calendars, chronographs (rattrapantes and flybacks only, please), big dates, moon phases, night sky star fields, sidereal time, equations of time, second time zones, alarms and repeaters of all stripes are often what push watchmakers to the boundaries of innovation, and beyond.

While we could list fascinating mechanisms devised by ingenious watchmakers 'til the cows come home, there's one particular complication that's rarely mentioned: dead seconds, where the second hand advances in increments of a whole second rather than a half or a quarter of a second. This is not a complication that jumps out at you. In fact, functionally, the seconds hand moves like that of a typical quartz movement. But aficionados will recognize it right away, because designing a mechanical movement to tick this way requires significant skill.


Typically, the dead seconds complication is powered by a constant force mechanism, with power taken from the mainspring and branching off the main gear train. Not so in the Grönefeld One Hertz. It's powered by a secondary gear train and a separate mainspring. The dead seconds complication has never been done this way before, probably because it's incredibly hard to minimize friction so that the second gear train doesn't affect the escapement or balance. To Grönefeld, this was a challenge, one that they decidedly nailed with the One Hertz.

Visually, a large dead seconds sub-dial with a sapphire chapter ring dominates the One Hertz's dial. Hours and minutes are indicated on a sub-dial at 2:00; a power reserve indicator resides at 12:00; and there's a winding/setting indicator at 3:00 (you toggle back and forth between winding and setting with a unique "push to set", "push to wind" crown). The watch is available in four limited edition versions: the Dune (20 pieces in red gold), the Ruthenium (30 pieces in high-grade titanium with a ruthenium dial), the Platinum (12 pieces in platinum) and the Titanium (30 pieces in high grade titanium).

"But why care about innovation that makes the watch appear to function exactly like a cheaper quartz version?" you may ask. Lovers of the One Hertz's unique take on a rare complication understand something you don't: the groundbreaking design inside, though hidden from the naked eye, makes this a singular timepiece. So if you ask them how often they need to change the battery, be prepared for a punch on the nose.
