Jacob & Co.’s God of Time is the World’s Fastest Tourbillon SJX Watches
Jacob & Co. s God Jan 14, 2026

Jacob & Co.’s God of Time is the World’s Fastest Tourbillon

To celebrate founder Jacob Arabo’s 60th birthday, Jacob & Co. has upped the ante for the tourbillon with the God of Time that’s styled on the Greek myth of time, but more importantly features the world’s fastest turning tourbillon that completes one revolution every four seconds – making it 15 times quicker than a conventional one-minute tourbillon. Initial thoughts The God of Time watch is a true showpiece of modern, extravagant high horology, blending both striking visual decoration and engineering prowess. The theme of time and its associated deity is built around the record setting tourbillon, the fastest of its kind. While we’re familiar with the perpetual quest for the thinnest watch, apparently the race towards the fastest tourbillon is also a thing. Much like most Jacob & Co. watches, the God of Time is loud and a large 44.5 mm in diameter. The leitmotif of Greek mythology is present in the thick case as well, which is modelled on an Ionic pillar. The size is a consequence of the movement, which is enormous – inside are four mainsprings – due to the energy requirements of the tourbillon. The hand-crafted figure of Chronos is remarkably detailed - truly in the spirit of ancient Greek statues. The dial is interesting, as the eye is drawn to both the Chronos figure and the unusually fast tourbillon, but falls short in legibility, though that’s clearly not the point here. The God of Time is one of those watches where time-telling is less important tha...

Introducing - The Capri, The Shaped, Dress Watch Collection of De Rijke & Co.

Dutch watchmaker de Rijke & Co. is among those that get noticed by thinking differently. The brand’s debut Amalfi collection, launched in 2019, was built around a clever rotatable centre case inside an outer cradle, a concept that fused functionality and design ingenuity. For its second collection, the brand steps away from case mechanics and […]

In-Depth: Breguet’s Constant-Force Magnetic Escapement

Earlier this week, Breguet rounded off its grandiose 250th anniversary with the unexpected launch of the Expérimentale 1 chronometer in Paris. Showcasing modern Breguet’s most impressive innovation to date - a magnetic constant-force escapement - the watch left many scratching their heads simply because the novel invention defies easy explanation. Here we explain the actual functioning of this remarkable invention, and why it represents such a significant step forward in terms of chronometry and escapement technology. The origins of the concept Before turning to the decidedly modern and futuristic Expérimentale 1, we must first take a short trip to the past and consider how the idea of using magnets in mechanical escapements first came to life. For that we must turn to the late 1930s, when Cecil Frank Clifford, Fellow of the British Horological Institute (BHI), started experimenting with oscillators maintained by magnetic rails or escape wheels.  He was granted a British patent in 1954 for a variety of magnetised escape wheels paired with elastic vibrating magnetic blades. The device would operate silently and Clifford envisioned it being used for naval underwater torpedoes, so the lack of ticking would be harder to pick up by sonars.  Iterations of Clifford magnetic escapements. His designs were rudimentary. The principle was that the escape wheel would be braked by a vibrating pair of magnetised blades (in several possible configurations), while simultaneously ...

De Rijke & Co.’s Final Miffy Moonphase is Here, in a New White Ceramic Case

One of the things I really enjoy about covering microbrands and small independents is seeing how young brands develop in unexpected ways over time. My first exposure to De Rijke & Co. was through Zach Weiss’s review of their Amalfi 1S back in 2020. At that point, the brand’s calling card was their trick case design that allowed the wearer to easily rotate the dial for a better viewpoint while driving, as well as customized design options so clients could effectively create their own unique version of the watch. This “gentleman driver’s” watch, as they referred to it, remains quite appealing, and the case of course is still a part of their collection. In no way, however, could it have predicted the success the brand would find making watches featuring the “Miffy” character, a staple of Dutch children’s books since the 1950s.  Over the last three years, De Rijke & Co. has released several Miffy themed watches that go well beyond simple character dials. The Miffy motif has been used to experiment with bold colors, lume, and different expressions of the moonphase complication. These watches are whimsical, a lot of fun, and quite far removed, in my opinion, from the earlier Amalfi pieces, and it’s fascinating to consider how the brand got to this point.  Today, they’ve unveiled what is said to be the final Miffy watch. According to the brand, the new White Ceramic Miffy Moonphase has been in the works for three years. It is, it turns out, quite complicated...

The unique story of Miffy and De Rijke & Co starts back in 2022, when Dutchman Laurens de Rijke, founder of his own watchmaking company, launched something very unexpected: the Miffy Moonphase. The iconic Dutch cartoon bunny is known and loved the world over, and carefully protected by a foundation honouring Dick Bruna’s (Miffy’s creator) […]

De Rijke & Co.’s Miffy Moonphase Returns for the Final Time in Steel

I’ve become a pretty big fan of De Rijke & Co. over the past few years, and am glad to see them experiencing so much success recently (I’m basing this on their booth at the New York City Windup Watch Fair being mobbed to the point that I couldn’t find room to introduce myself to brand founder Laurens de Rijke until the last day of the show). If I’m being honest, though, I’ve been a bit mystified by the whole Miffy thing. The Miffy Moonphase watches have become something of a viral sensation for De Rijke, but I’ve always assumed the limited editions were snatched up by an international audience with more Miffy familiarity than the typical American watch consumer. But earlier this year, traveling back from Geneva Watch Days, I had a connection in Amsterdam, and waiting at the gate I noticed an American family (the Boston accents gave it away) with two young children and several shopping bags full of Miffy memorabilia purchased, I assume, somewhere in Schiphol Airport. It dawned on me then that the Dutch cartoon was not some closely held regional secret – it was just I’m, as usual, painfully out of touch.  Today, De Rijke launches a pair of new Miffy Moonphases with green dials that follow the format of their previous releases closely. This, according to De Rijke, is the final Miffy Moonphase release in a steel case, and it consists of both a single and double moonphase, each in an edition of 50. The double moonphase watches have been particular favorites sin...

The Jacob & Co. Bugatti Tourbillon and its V16 Engine Automaton SJX Watches

The Jacob & Co. Bugatti Tourbillon and its V16 Engine Automaton

Just after Bugatti took the covers off its Tourbillon hypercar, Jacob & Co. presents a watch to match, the Bugatti Tourbillon. Integrating some of the most distinct design elements of the car, the Tourbillon watch is extravagant in both style and mechanics, combining a retrograde time indication with a flying tourbillon, and a striking automaton modelled on a V16 engine.  Initial thoughts As over the top as the Tourbillon wristwatch might be at first, it unexpectedly incorporates subtle details and nods to the newest Bugatti automobile. Apart from the obvious engine automaton, the watch case is modelled on the car’s unique instrument cluster layout and indications. The mechanical instrument cluster in the Bugatti Tourbillon hypercar The piece is unapologetically automotive, taking the same approach in emulating the eponymous hypercar first seen in the Jacob & Co. Bugatti Chiron Tourbillon. Like the Chiron wristwatch, the Tourbillon is an oversized mechanical object for the wrist. A mini engine Clearly the showpiece of the Tourbillon is the V16 engine automaton with an engine block milled from sapphire. The mock engine features eight pairs of articulated titanium pistons and polished parts modelled on the intake manifolds of an actual Bugatti V16. When the automaton is engaged, the pistons “fire up” in the appropriate sequence, putting on a very interesting show.  Above the V16 engine block sits the time indication. Arranged to resemble the instrument cluster found ...

De Rijke & Co. Partners with Illustrator Guy Allen on a Trio of Limited Editions Inspired by the Amalfi Coast

Over the last few years, De Rijke & Co. has built out an unlikely niche within the watch world: making highly desirable character watches featuring the beloved “Miffy” character, a staple of children’s books in the Netherlands, the brand’s home country. After the launch of the first successful Miffy moonphase, there have been several additional variants released in short order, offering colorful takes on a whimsical subject. I think most would probably agree that this represented a somewhat unexpected turn in the life of De Rijke. When we first encountered them, it was as a maker of a clever driver’s watch, with a unique case that allows the dial to be rotated within a cage to suit a driver’s needs. What’s more, De Rijke has always offered customers the ability to customize their watches to a high degree, allowing for a truly bespoke experience. The Miffy watches have been fun, but if you knew the brand before, they felt almost like a diversion.  De Rijke never stopped making those custom pieces of course, so it would be unfair to ask “What happened to this brand?” or something similarly dramatic. They haven’t gone anywhere, but clearly took an opportunity to capitalize on a watch concept that became a bit of a sensation with a very specific crowd. But now, for the first time since I’ve been writing about them, De Rijke is back with a new series that is not Miffy based, but still has a sense of that whimsy. The new entries in the Amalfi series are ba...

Explained: The Detent Escapement SJX Watches
Breguet s natural escapement May 8, 2024

Explained: The Detent Escapement

Among the many different escapement types, one in particular stands out, the detent escapement. Taking its name from détente, French for “trigger”, this system is often considered to be the purest type of escapement due to its efficiency and virtually lubrication-free operation. Any sort of mechanical clock or watch requires an escapement, a mechanism that transfers torque from the power source to the regulating organ. The escapement bridges the steady rotation of the gears in the going train and the oscillation of the balance. As a result, the escapement fulfils a double function, both maintaining the swing of the balance and regulating the discharge speed of the mainspring and going train. The detent escapement was invented in the second half of the 18th century,  somewhat simultaneously but independently by the English watchmakers Thomas Earnshaw (1749-1829) and John Arnold (1736-1799). A somewhat similar escapement was prototyped by the Frenchman Pierre Le Roy (1717–1785) some three decades earlier, but the modern detent escapement is derived mostly from Earnshaw’s design. Initially, the escapement was conceived for use in marine chronometers, explaining why it is also known as a chronometer escapement. The chronometer escapement also inspired many innovative subsequent escapements, like the Breguet’s natural escapement, the Robin escapement, and the Daniels co-axial. Drawings of detent escapement types taken from ‘The Marine Chronometer: Its History and ...
