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.

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.

Hands On: Jacob & Co. Astronomia Revolution SJX Watches

Hands On: Jacob & Co. Astronomia Revolution

Historically known for its over-the-top jewelled watches and oversized complications, Jacob & Co. recently debuted a watch that is very much quintessential Jacob, but surprisingly novel in mechanical terms. The Astronomia Revolution sticks to the distinctive, extra-large styling that defines the model, but contains an all-new movement that combines several complex assemblies into an even more complex movement, all in the name of a dynamic, fast-rotating display. Carrying the tourbillon and time display, the carousel is impressively quick and completes one revolution a minute, a feat made possible by a one-sixth-of-a-second constant-force mechanism and a differential for the time display. The kinetic nature of the dial means this is unlike any other mechanical watch. Initial thoughts The Astronomia Revolution made it into my list of notable complications unveiled at Watches & Wonders earlier this year: “[The] Revolution seems like yet another variant of the New York jeweller’s bestselling and bulbous timepiece… Except that it is not… While past versions of the Astronomia required between ten to 20 minutes or more for the carousel to complete one rotation, the Revolution does it in one minute [and] functions as a minute hand. To move a component that large at such a speed is unprecedented…” Which pretty much sums it up. It looks like a typical Jacob & Co. watch, but is much more interesting mechanically. That is because the movement goes against the prevailing co...
