Bell & Ross Introduces the BR 05 Skeleton Nightlum

Very much the fashion of today, sports watches with integrated bracelets have proliferated rapidly at every level of the price spectrum. At the more accessible end is the Bell & Ross BR 05 launched two years ago and now available in three formats: time-only, chronograph, and skeleton. Continuing a glow-in-the-dark theme established by several recent models, Bell & Ross (B&R;) now unveils the BR 05 Skeleton Nightlum. Legible in the dark Initial thoughts Though the BR 05 was contentious because of its design, I’m a fan. The square case – with perfectly aligned bezel screws – evoke B&R;’s signature watches like the BR 01 and BR 03, making the BR 05 instantly recognisable. And it is executed well, with strong finishing on the case and bracelet considering the price. The most striking BR 05 model is arguably the skeleton variant, and that remains true with the BR 05 Skeleton Nightlum. Revealing most of the movement, including key bits such as the balance wheel and mainspring, the skeleton is a good looker. The BR 05 Skeleton Nightlum to be more attractive than its predecessors, including last year’s iteration in blue. It has a tactical feel thanks to the all-black movement, bringing to mind the recent BR 03 Diver Military and feels true to the brand’s history of watches for military and police personnel. Notably, the new Skeleton Nightlum has a clear dial, in contrast to the blue-tinted dial found on last year’s Skeleton Blue. The clear finish gives the Sk...

Sinn Introduces the R500 Chronograph

Famous for its no-nonsense “tool” watches, some of which are supplied to the German military and law enforcement, Sinn’s latest debut is slightly different. Inspired by auto racing, the R500 chronograph is a watch that shows the brand can have some fun, while being properly functional. Modelled on a funky chronograph Sinn produced in the 1970s, the R500 is a “bullhead” chronograph, with the twin pushers positioned like horns at one and 11 o’clock. While the style very much evokes the 1970s, the R500 is built like a robust modern wristwatch, with titanium case rated to 200 m that’s resistant to extreme low and high pressures. Initial thoughts Radically different from Sinn’s usual fare of pilot’s or military-style watches, the R500 is arguably the most interesting watch amongst the brand’s recent releases. It’s recognisably 1970s in style, but with a clean dial design that avoids the “exotic” dial found on the vintage original, which was a typically 1970s feature that can look dated today. A notable element of the dial design is the power reserve indicator at 12 o’clock, which seems unnecessary for an automatic watch. But German rally champion Peter Göbel, speaking during a video interview for the launch of the R500, noted that a fully-wound mainspring is crucial before starting a race – since the chronograph can be used to time laps – so it is useful in that context. And it’s also unusual against the broader landscape because “bullhea...

Inspired by a bulldog, MB&F;’s Horological Machine No. 10 features a rounded, stocky body; the time display forms its eyes; and the stout legs form the lugs, hugging its owner fiercely and loyally.

Louis Moinet accomplished Aug 3, 2020

In-Depth: A History of the Pulsations Chronograph

In 1816, Louis Moinet accomplished a first in watchmaking: a timepiece that could precisely track elapsed time. Measuring periodicity on demand had been accomplished before, but the French watchmaker’s invention gave it the functionality and exactness that we expect today. In assessing prototypes, we often tend to forgive their shortcomings and rosily reminisce, rewriting flaws as charms. Moinet’s timepiece, however, was a prescient opus. The layout of the dial had the now-familiar large central hand and elapsed time in subdials. Two pushers controlled the start, stop and reset functions, the power reserve lasted over 30 hours, and the mainspring could be wound while the timing mechanism was engaged to allow for longer timing runs. Most impressive, though, was its precision. Louis Moinet’s compteur de tierces of 1816. Image – Louis Moinet Named the compteur de tierces, or “timer of thirds”, Moinet’s invention ran at 216,000 beats per hour, measuring time down to one-sixtieth of a second. To allow for this ambitious exactitude to be utilised, the central chronograph hand completed revolutions once per second – such that the user could easily see which sixtieth of a second the period in question ended on - and the watch had an extra sub-dial for tracking elapsed seconds in addition to those for the minutes and hours. Whys and wherefores An impressive story, except that it’s missing something. Why did Moinet build it? And what did he use it to measure? A...

Oris Big Crown ProPilot X Calibre 115 Review

The Big Crown ProPilot X Calibre 115 is simply a watch that explains Oris’s true personality. The Big Crown ProPilot X Calibre 115 goes back to the roots of what mechanical watches are all about. In today’s world, so many of us know what the things around us can do, but rarely actually know how they work.  The same logic applies to mechanical watches too. We see brilliant timepieces made and know what they can do, yet rarely see or understand the inner workings behind them. This is the idea behind the Big Crown ProPilot X Calibre 115, to show as much as possible how the true inner workings of a mechanical watch operate.  Oris Big Crown ProPilot X Calibre 115 There is almost a natural connection between a mechanical watch and its owner. If we don’t wind it, or even yet move, we won’t drive enough power to turn the mainspring which ultimately powers the movement. This is what Oris is trying to show with the Big Crown ProPilot X Calibre 115.   Oris Big Crown ProPilot X Calibre 115 Oris’s Big Crown ProPilot X Calibre 115 was inspired by nature, in particular, a Valley named Waldenburg, which surrounds the village of Hölstein. This particular village is significant to Oris, as it is there where the brand originally began. Oris was founded in 1904, and since then the brand has been based in Hölstein. It’s no wonder then that they would go back there to find sources of inspiration for arguably the “most Oris watch” they have ever made.  Oris Big Crown ProPi...

Jaeger-LeCoultre Introduces the New Master Control Collection

A mainstay of Jaeger-LeCoultre’s catalogue for almost three decades, the Master Control made its debut in 1992 and has been facelifted every couple of years since. Fresh off the press at Watches & Wonders 2020, the latest Master Control collection forgets the facelifts and is instead throwback to the inaugural line-up of three decades ago. The new range reproduces the models and style of the originals, including the popular, entry-level Master Control Date, but it also includes an all-new model, the Master Control Chronograph Calendar. From left: Master Control Date, Master Control Calendar, and Master Control Geographic And the Master Control Chronograph Calendar New tech, classic style While retaining the look of the originals, the new Master Control models are ever-so-slightly larger, now measuring 40 mm (while the 1990s originals were mostly 37 mm). More importantly, the new watches have been fitted with newly-upgraded movements equipped with silicon escapements. The cal. 899AA of the Master Control Date Though JLC has used silicon escapements in the past, most notably in the Master Compressor Extreme LAB 2 and the more recent Tourbillon Celeste, the movements in the new Master Control watches are the first affordable, regular-production models to feature such escapements.

Hands-On: Brivet-Naudot Eccentricity

French watchmaker Cyril Brivet-Naudot made his debut two years ago with the Eccentricity, a time-only watch that’s fascinating and impressive on many fronts. Not only is it almost entirely made by hand, the Eccentricity is intriguing in design and mechanics – from the overall architecture to details like the key-winding mechanism and regulator-style time display with a twist, and above all, the proprietary escapement. Just 29 years old, Mr Brivet-Naudot began working on the Eccentricity after graduating from the École Polytechnique Fédérale de Lausanne (EPFL), one of Switzerland’s best technical universities. Prior to that, he earned a diploma in watchmaking from the Lycée Edgar Faure in Morteau, a small town in eastern France that borders Switzerland. The school has gained a reputation for producing imaginative watchmakers, many pursuing a similar style that’s inspired by 19th century pocket watch movements, including Theo Auffret, a peer of Mr Brivet-Naudot. The result of three years of development, the Eccentricity is very much in the same vein as the watches produced by Mr Brivet-Naudot’s fellow graduates. It artfully combines a 19th century aesthetic sensibility with exotic features, including a novel, free-eccentric escapement, for which the watch was named. And it is built by hand: with the exception of the mainspring, hairspring, jewels and crystals, every component of the watch was made from scratch by Mr Brivet-Naudot, without the aid of CNC machine...

Jaeger-LeCoultre Introduces the Atmos Transparente

As crucial to Jaeger-LeCoultre’s identity as the swivelling Reverso wristwatch, the Atmos clock remains a unique and intriguing invention almost a century after its invention – a clock that runs on air. Having been offered in a variety of iterations over the years, including several by industrial designer Marc Newson, the latest is the Atmos Transparente, a clean, modernist reinterpretation of a longstanding model in the line-up. Despite being synonymous with Jaeger-LeCoultre, the Atmos was actually invented by someone else, who was inspired by a much older idea. Clocks wound by changes in atmospheric temperature were invented sometime in the 17th century, but remained largely experimental until French engineer Jean-Léon Reutter invented the Atmos in 1928. His idea was actually an evolution on the 400-day clock, which is regulated by an exceptionally slow pendulum and need only be wound once a year. The magic of air The genius of Reutter’s invention was a sealed metal bellows containing mercury, which expanded and contracted with changes in temperature, thus winding the clock’s mainspring. Despite its novelty, Reutter’s clock met with little commercial success – early Atmos clocks marked “J.L. Reutter” are rare but not especially valuable – leading him to sell the idea to LeCoultre in 1935 (and two years later the company joined forces with Edmond Jaeger to form Jaeger-LeCoultre). The company refined his concept, with the key improvement being the repl...

F.P. Journe Octa Réserve de Marche Dec 2, 2019

Hands-On: F.P. Journe Octa Réserve de Marche Prototype

As has become tradition, a good part of Phillips’ upcoming New York watch auction is a memorabilia sale of sorts, including watches owned by Marlon Brando, golfer Jack Nicklaus, and astronaut John Glenn, as well as the Urwerk worn by Robert Downey Jr. while playing Iron Man in Avengers: Endgame. The auction also includes a piece of historical horological memorabilia: an F.P. Journe Octa Réserve de Marche prototype. The prototype is largely identical to the later, serially produced version of the watch – the case is platinum and the dial, yellow gold – but is marked as a prototype on the case back, and also bears the various traits unique to early watches made by Francois-Paul Journe. The cal. 1300 Launched in 2002 and discontinued in 2014, the Octa Réserve de Marche was the brand’s first entry-level wristwatch, powered by an automatic movement, the cal. 1300. Originally conceived to have an eight-day power reserve – hence “Octa” – the movement instead has a power reserve of 120 hours, or about five days. Reputedly constructed with a gear train borrowed from a robust and well-known hand-wind movement plus an extra-large mainspring, the cal. 1300 was the base calibre for the entire Octa line. Although a variety of complications were added on top, ranging from the Octa Chronograph to the annual calendar of the Octa Calendrier, all versions of the movement had identical height of 5.7mm regardless of function. The slimness and smart construction did come at th...

Introducing the Hasta la Vista Revolver 8-Day Table Clock

A recent startup dedicated to creating unusual objects, The Unnamed Society makes its debut with a table clock shaped like the Colt Bisley Model revolver of the early 20th century. The clock is produced by L’Epee 1839, the Swiss clockmaker that is responsible for practically all of the unconventional and avant-garde mechanical clocks of recent years, most famously those designed by MB&F; but also Chanel. But it’s undoubtedly the success of MB&F;’s sci-fi clocks that have compelled various brands, old and new, to develop their own L’Epee 1839 clocks. Named Hasta la Vista, “goodbye” in Spanish, the clock is the shape and size of an actual revolver, measuring 350mm or just under 14 inches long. It’s made of steel and palladium-plated brass, and can be mounted on its accompanying base either via the grip or the barrel. Pictured here with the grip made of horn from the bighorn sheep, as well as engraving on the frame Mechanically it is identical to the 8-day clocks L’Epee 1839 has produced in other shapes and sizes. The time is indicated by two revolving cylinders – one each for the hours and minutes – that take the shape of the rear section of the pistol frame. The escapement, wheel train and mainspring are where the cylinder (which contains the bullets) would be. Winding is accomplished by a key that’s inserted into the end of the barrel. Though it’s a limited edition of 50, each clock can be customised with a variety of options offered for the g...

Richard Mille Introduces Sep 21, 2019

Richard Mille Introduces the RM 50-04 Kimi Räikkönen

As complications go, the RM 50 is the ultimate Richard Mille, combining a tourbillon and split-seconds chronograph. Descended from the RM008 of 2003, one of the brand’s foundational models, the top of the line complication now has now been dressed up in new livery for Finnish Formula 1 driver Kimi Räikkönen, who drives for the Alfa Romeo Racing Team. Launched at the start of the 2019 Singapore Grand Prix, the RM 50-04 Tourbillon Split-Seconds Chronograph Kimi Räikkönen is large, lightweight, and complex, and dressed in a red, white and black colour combination that’s the same as the livery on the Alfa Romeo C38 Formula 1 car. Kimi Räikkönen Though it’s a mass of details and colours, the dial is actually easily to decipher. The two chronograph sub-dials are the six and nine o’clock. The fan-shaped indicator at 11 o’clock is the power reserve, and its mirror image to the right is the torque indicator. This indicates the level of wind in the mainspring, with the ideal being between 53Nmm and 65Nmm; “Nmm” is short for Newton millimetre. And at three o’clock is the power reserve display. Made of various lightweight carbon composites, the watch case is generously sized, like other top of the line Richard Mille complications – 44.5mm in diameter and 16.1mm high. The front and back plates are white Quartz TPT, while the middle is Carbon TPT. Both composites are made by North Thin Ply Technology (NTPT), a Swiss lightweight composite specialist that’s...
