By the time they have over 30 horological patents under their belt, you would assume that a watchmaker would be spoken of in the same breath as the modern independent greats, like F. P. Journe or Philippe Dufour. And yet despite working for Patek Philippe, Ulysse Nardin, and Girard-Perregaux over the years, you may well not have heard of Stéphane von Gunten.
Last year, Stéphane launched Haute-Rive, a shiny new independent watchmaker and the first with the master horologist and inventor at the helm. As alluded to, the fifth-generation watchmaker had been working quietly behind the scenes for decades, but it took the impetus of Covid for him to make the big leap. But before we get into his modern watches, it’s worth looking at his horological past – and one watch, in particular.
It’s pretty common for the Pope to receive gifts. There’s a reason the last Pope had a Lamborghini and it’s not because he’s an adrenaline-fuelled hype beast. In 1888, to mark the jubilee of Pope Leo XIII, that gift came in the form of a gorgeous gold pocket watch. Nothing too unusual there – except that the power reserve was a staggering 40 days. That’s well over a month of power on a single wind. The maker of that watch was Stéphane’s ancestor, Irénée Aubry.
Power reserve is actually something that Stéphane has pushed throughout his career, no matter what brand he’s working for at the time. No multi-axis tourbillons, no complex chiming arrays, just that one, incredibly useful aspect of a timepiece’s spec sheet. And it’s that aspect that Haute-Rive is built around. The brand’s debut watch says it all, the phenomenal Honoris I.
On the surface, the Honoris I is an aesthetically elegant timepiece in the vein of other independent watchmakers. It comes with a grand feu enamel dial in a gold case, sized at a large-but-wearable 42.5mm. And yet there’s more going on than a glance can take in. For one, while the six o’clock tourbillon, the central gear bridge and the so-called ‘wheel of time’ at 12 o’clock are all visible, they’re not visibly connected. This means that while the elements are on top, the real work is happening underneath that enamel.
It’s a similar concept to something like MB&F’s Legacy Machines, just a bit more subtle. The thing is, while that over-and-under of components defines the look of the watch, it’s what you can’t see that defines what it actually is. You see, while his ancestor may have managed a watch with a 40-day power reserve, Stéphane has achieved 41, around 1,000 hours. And in a single-barrelled wristwatch at that.
To get there, the mainspring is 3m long. That’s a single, 3-metre-long piece of metal that’s been curled into a spring that can fit in one small section of a none-too-large watch. While it sounds simple, there’s a reason it’s not been done before. So how do you fit that kind of thing in a wristwatch? By turning the mainplate into the barrel. Obviously.
As if upsetting the entire architecture of a watch wasn’t enough, anything with a power reserve this long likely needs a winding system more substantial than a standard crown. For one, that’s a lot of twisting a tiny component; for another, it would put a lot of force on the crown’s stem as you approach the upper power limit. So, Stéphane took a different approach and commandeered the bezel.
As you’ve likely noticed, the bezel is grooved with grips, allowing you to easily turn it counter clockwise to wind the mainspring. It’s still a fair amount of winding of course, you’re funnelling a lot of energy in, but it’s far superior to the crown, and you can keep an eye on how much you’ve wound it on the back of the watch. And hey, you only need to do it once a month – with a 10-day safety buffer.
For many watchmakers, power reserve is a nice thing to have; a selling point but not exactly a headline-grabbing one. A few hours here or there is more an afterthought than a core idea. Stéphane on the other had has used Haute-Rive to completely change the architecture of a traditional timepiece, specifically to put power reserve at the metaphorical and literal heart of the watch.
Haute-Rive is of course a brand that won’t have many collections in the future and won’t produce hundreds of watches. But if the Honoris I is anything to go by, he might just be one of the most low-key exciting independents around – and if you didn’t know about him before, you do now. You’re welcome.
