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

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 ...

In-Depth: Girard-Perregaux’s True Constant-Force Escapement

Ten years after it arrived on market, Girard-Perregaux revived its most notable modern-day invention with the Neo Constant Escapement. Operating on the same principles as the original, the Neo Constant Escapement (NCE) features an upgraded movement inside a more compact case. A combination of a historical concept originating with Abraham-Louis Breguet and cutting edge horology, the NCE retains the defining invention of the original – a true constant-force escapement. “True” because the constant-force mechanism, comprising a lozenge-shaped silicon spring, is integrated with the pallet lever, which in turn interacts with a “natural” escapement of twin escape wheels. While the key concept has been retained, the rest of the NCE, however, has been improved over the original, with wearability in particular having been enhanced. Initial thoughts The fundamental concept of the NCE is appealing because it successfully combines a significant historical invention, Breguet’s double-wheel escapement, with an innovation that is entirely 21st century, a compliant mechanism in silicon. Both are brought together in an elegant yet ingenious manner. The basis of the movement is Breguet’s échappement naturel, the “natural” escapement with two wheels that has been adopted in the modern day, in a variety of modified forms, by Voutilainen, F.P. Journe, and Charles Frodsham. But the natural escapement here has been enhanced with a constant force mechanism made up of a single pi...

Girard-Perregaux Neo Constant (Force) Escapement: The Evolution of a Revolution

While it is remarkable how Girard-Perregaux made the movement, it is even more astonishing how they turned it into such an incredibly good-looking watch. Compared to its predecessor, the Neo Constant Escapement has a very wearable size of 45mm in diameter at a thickness of 14.8mm. It sits nicely on even a smaller wrist thanks to relatively short lugs, while the titanium case keeps the weight down.
