Jacob & Co Astronomia Regulator

The world of haute horology is no stranger to innovation. Watchmakers constantly push the boundaries of design and technical complexity, and Jacob & Co is a brand that is synonymous with this relentless pursuit of the extraordinary. Their latest release, the Astronomia Regulator, is a perfect example of this. It takes a classic complication, the regulator, and reimagines it in a way that is both stunning and technically groundbreaking. This two-part series will delve into the Astronomia Regulator, exploring its history, technical details, and the unique design that sets it apart.

The regulator, a timepiece known for its distinct separation of hours, minutes, and seconds displays, has a rich history. In the early days of industrialized watchmaking, workshops relied on large, highly accurate clocks to regulate their work. These "regulator" clocks needed to be easily readable from a distance, and their design, with separated sub-dials for hours, minutes, and a prominent central seconds hand, was born from this practicality. As timekeeping transitioned from workshops to wrists, the regulator evolved into a pocket watch and then a wristwatch, but the basic layout remained the same.



Jacob & Co.'s Astronomia Regulator takes the regulator concept and spins it on its axis, literally. This is the first timepiece to feature a vertical, rotating movement that completes a full revolution every sixty seconds. Imagine a miniature carousel, whirling within the confines of a wristwatch, with each "horse" carrying a timekeeping function. The effect is mesmerizing and sets the stage for a truly unique watch collecting experience.

For a watch collector, the first impression is everything. The Astronomia Regulator is a conversation starter on every level. The 43mm rose gold case is a study in contrasts. The polished gold offers a luxurious warmth, while the generous use of sapphire crystal provides a clear view into the heart of the watch. The lugs are openworked, further reducing the visual weight of the case and ensuring the focus remains on the captivating movement within.

The bulging sapphire crystal reveals a symphony of horological innovation. The most prominent feature is the triple-armed platform that rotates counter-clockwise every sixty seconds. One arm holds a double-axis flying tourbillon, a marvel of engineering that seems to defy gravity as it spins on two axes simultaneously. The other two arms are dedicated to the timekeeping functions. Blue translucent sub-dials display the hours and minutes, their classic fonts and gold hands offering a touch of tradition amidst the whirlwind of innovation.



But here's the twist: These sub-dials are geared to rotate in the opposite direction of the main platform, at the same speed. This ensures that they remain upright and readable at all times. It's a subtle detail, but one that exemplifies the thoughtful engineering that has gone into the Astronomia Regulator.

The Astronomia Regulator is the latest chapter in Jacob & Co's long history of creating haute horology masterpieces that push the boundaries of what a watch can be. Their Astronomia Tourbillon introduced the world to a vertical, rotating carousel movement in 2016, and the Astronomia Revolution upped the ante in 2023 with a movement that completed a full rotation every minute. The Astronomia Regulator takes this concept even further, adding the complication of the separate regulator displays and seamlessly integrating them into the rotating platform.

Powering the Astronomia Regulator is Jacob & Co.'s all-new Caliber JCAM56, a mechanical marvel boasting 552 components. That's an extraordinary number for a watch movement, a testament to the watch's complexity. Designed with a focus on slimness, this groundbreaking caliber allows for the relatively compact 43mm x 18mm proportions of this Astronomia.



However, mere size isn't the goal here. It's the sheer level of mechanical ingenuity required to make such a movement function reliably. You see, a watch movement isn't some static construction. It's a symphony of tiny parts, meticulously calculated and balanced, a testament to micro-engineering on an almost unbelievable scale.

Let's put the Astronomia Regulator's movement into perspective. Picture a traditional carousel, but scaled down to the size of a dime. Now replace the carousel horses with a tourbillon, time displays, and all the gears necessary to keep them moving. Finally, make that miniature carousel spin a full rotation every minute. That's a lot of moving mass, and moving things in the world of mechanics requires energy. Lots of energy.

To conquer this challenge, Jacob & Co. integrated a patented constant force device into the movement. Like its name implies, this device provides a steady, constant supply of power to the tourbillon and time displays, ensuring smooth operation and better accuracy. It's an essential ingredient in the recipe that makes the Astronomia Regulator's whirlwind possible.

The materials used throughout the Astronomia Regulator are as unconventional and eye-catching as its design. The case is crafted from warm 18k rose gold, a luxurious counterpoint to the almost space-age aesthetic of the movement. The use of blue polycarbonate for the sub-dials adds a pop of color and a sense of modernity. However, the sapphire crystal is the true star, showcasing every facet of the meticulously finished movement beneath.



The Astronomia Regulator is, without a doubt, an exhibitionist's watch. But it's so much more than mere theatrics. Think about it: a centuries-old complication, repurposed for a vertical display, built on a spinning platform, regulated for accuracy and reliability... it's the sort of horological audacity only a brand like Jacob & Co. could deliver. It's the kind of watchmaking ambition that, for serious collectors, is utterly irresistible.

The movement is meticulously finished by hand, a process that likely takes hundreds of hours in itself. Every surface, every angle has been considered, adding a level of craft that transcends mere timekeeping. This attention to detail reminds us that despite its futuristic looks, the Astronomia Regulator is built upon the time-honored traditions of Swiss watchmaking.

With a limited edition of 250 pieces, the Astronomia Regulator is destined to be a rare bird. This scarcity only adds to its appeal for collectors, who often see such watches as investments as much as timepieces. With its $280,000 price tag, the Astronomia Regulator resides in the rarefied air of haute horology, a domain where price isn't a mere number, but an indicator of prestige and mechanical achievement.



The Astronomia Regulator is a watch that defies convention in every way. It's visually stunning, technically brilliant, and undoubtedly a bold statement. If your idea of a fun watch is a whimsical, gravity-defying marvel of motion, then Jacob & Co.'s latest creation might be the perfect addition to your collection. However, even if audacious watchmaking isn't your cup of tea, the Astronomia Regulator reminds us that the world of watches is vast, diverse, and constantly evolving. From traditional to cutting-edge, there's always something exciting around the corner, and we can appreciate the innovation on display even if this particular watch isn't our style.

The Jacob & Co. Astronomia Regulator is a testament to the brand's unwavering pursuit of "Inspired by the Impossible." It proves that even the most established horological traditions are ripe for a high-octane, Jacob & Co-style revolution.
