Entry Level: The Omega De Ville Prestige Co-Axial Chronometer

Omega's most accessible co-axial has charm to burn.

Burgess Clock B, The World’s Most Precise Pendulum Clock, Is Made To A 250-Year-Old Design By John Harrison, Longitude Prize Winner And Inventor Of The Marine Chronometer - Reprise

Two-hundred fifty years ago, Longitude Prize-winning clockmaker John Harrison made clocks losing just one second per month. But that wasn't enough for him: in his later life, Harrison claimed that he could make a wall clock with a then-unheard-of-precision of just one second over 100 days! And 250 years later, it turns out he was right.

Omega Speedmaster Moonwatch Professional Co-Axial Master Chronometer 2021

Omega released the latest update to the Speedmaster Moonwatch Professional chronograph early this year with some much appreciated upgrades. Several changes were made to the dial and case, but most notably, the movement is now co-axial and anti-magnetic. For speedy owners, a magnetised Speedmaster happens once ever so often and can be quite a pain sometimes. Apart from its technical improvement, the new iteration also features several design updates to the dial and case.

Bernhard Lederer Debuts the Central Impulse Chronometer Prototype

A member of the Académie Horlogère des Créateurs Indépendants (AHCI) since its founding in 1985, Bernhard Lederer is a veteran of independent watchmaking. Though known amongst collectors for having founded the brand BLU in 2002, Mr Lederer is more of a watchmaker’s watchmaker, supplying movements and complications via his company MHM (short for “Manufacture de Haute Horlogerie et Micromécanique”). Born in Germany but based in Switzerland for decades, Mr Lederer’s technical prowess is on full view with his latest creation – the Central Impulse Chronometer (CIC). Seemingly a mere three-hand wristwatch on the front, the CIC is a actually a significant accomplishment – and undoubtedly one of the most notable watches of 2020 from a technical perspective. The movement is equipped with a natural escapements as well as dual gear trains. The construction is familiar – Mr Lederer describes it as a tribute to the late George Daniels and his landmark Space Traveller pocket watch – but improved and refined with the addition a remontoir d’egalité constant force mechanism for each going train. Initial thoughts With seemingly everything already having been done in watchmaking, it is not often that we encounter a genuinely interesting – and improved – twist to an already uncommon escapement. Here Mr Lederer rejuvenates the centuries-old idea of the natural escapement, but elevated by the added complexity and performance gains of twin remontoir going tr...

The Secrets of F. P. Journe’s Resonance Chronometer

Exclusive: TAG Heuer To Introduce A COSC Certified Flying Tourbillon Chronograph For Under 20,000CHF (14,900CHF !!!)

Today, recently appointed General Manager of TAG Heuer, Guy Semon dropped a bombshell on the Revolution team with news of an upcoming watch that certainly is a provocative statement of intent. We at Revolution love our watches, and the passing parade of the best that the Swiss watch industry has to offer is by no means something […]

In Plain Sight: Revealing The Secrets Of F. P. Journe’s Resonance Chronometer

This story is something of a mea culpa. Many years ago, when I was yet green with youth and correspondingly filled with overweening self-confidence, an independent watchmaker –a respected one; a student of the work of such luminaries as Janvier and Breguet –named Francois Paul Journe, came out with a most intriguing watch. That watch was […]

Hands On: Jaeger-LeCoultre Master Control Chronometre

The most talked-about release from Jaeger-LeCoultre (JLC) at Watches & Wonders was the refreshed Master Control collection, which debuted on a surprising integrated bracelet. Available with or without perpetual calendar or power reserve complications, the Master Control Chronometre is powered by the latest version of the brand’s long-running cal. 899, which is now certified by both COSC and a new internal standard called the High Performance Guarantee (HPG). Initial thoughts Since the Master Control Chronometre debuted at Watches & Wonders, I have been asked multiple times whether it is a dress watch or a sport watch. Setting aside the issue of the false dichotomy that exists between these categories, the Master Control Chronometre presents itself primarily as a dress watch on a bracelet. While the bracelet’s angular facets evoke those of the Vacheron Constantin Overseas, the staid Master Control dial is what defines the look. The simple sunray finish and slim hands — not to mention the lack of any lume — firmly root the Master Control Chronometre in the dress watch category. The soft blue and brown dials are each attractive in their own right, with colour-matched date wheels to avoid any harsh transitions. While the text is arguably superfluous, the ‘Chronometre’ label is more interesting than the typical ‘Automatique’ text that mars most Master Control dials. In terms of the value proposition, it’s a tale of two metals. The stainless steel model isn’t...

Only Watch 2021: Atelier de Chronométrie AdC21

Founded to give new life to vintage chronometer movements and resurrect old-school designs, Atelier de Chronométrie (AdC) has completed only a few watches to date, but has quickly become known for wristwatches that are elegantly refined inside and out. In its inaugural outing at Only Watch, the watchmaker put together the AdC21, a time-only watch that is simple but executed with lavish detail, and dressed in a nostalgic, “pink on pink” livery. Like AdC’s other creations, the AdC21 is powered by a movement that started life as a vintage ébauche before being upgraded with parts fabricated by hand in-house. And the movement has been finished to level far beyond what the vintage calibre ever was. Initial thoughts AdC watches are intrinsically appealing to enthusiasts who favour old-school dress watches, which often have discreet, refined details that are uncommon in contemporary watches. One of the brand’s cofounders is a vintage watch dealer whose eye and experience explain the house style. At the same time, AdC elevates the design with the artisanal quality of the case and movement, most of which are made in house. The AdC21 is arguably the best time-only watch the brand has created to date. Entirely classical yet novel, the dial has a two-tone finish matched with an unusual interpretation of the “scientific” dial. And the case is also more elaborately constructed than those found on AdC’s earlier works. Beyond the design and craft, the shades of pink that d...

Full hands-on analytical review of the Jämes-César Pellaton Royal Marine Chronometer, a very special tourbillon with exceptional finishing.

The Lengths Of Time: La Chronométrie Ferdinand Berthoud

Extraordinary moment. A watch that transmits all the achievements of Berthoud as the father of French marine chronometer in a brilliantly contemporary timepiece. Karl-Friedrich Scheufele has revived the mythology of one of horology’s most mythical names with beautiful modern eloquence. Karl-Friedrich Scheufele is better known as the head honcho of Chopard timepieces, but he has […]

Introducing - The new Ferdinand Berthoud Chronometre FB 3SPC.2-1

Following the resurrection of the name Ferdinand Berthoud by Chopard’s co-president Karl-Friedrich Scheufele in 2015, with the introduction of the Chronomètre FB1, a superb tourbillon watch with fusée-and-chain device, followed by the no less spectacular Chronomètre FB2, the brand presented another award-winning watch, a superb wrist chronometer with cylindrical balance-spring named the Chronomètre FB 3SPC – […]

Hands On: Nouvelle Chronometrie Montre Ordinaire

One of the most intriguing debuts in independent watchmaking this year is Nouvelle Chronometrie with its Montre Ordinaire. Despite the name, Nouvelle Chronometrie is actually Japanese, and the “ordinary” watch is a tourbillon chronometer inspired by 20th century observatory chronometer watches and dressed in formal Breguet attire. With its rigorously classical design, evident on both the front and back, the Nouvelle Chronometrie is distinctly Japanese at heart in how it careful reproduces and enhances traditional watchmaking – executed with a great deal of attention to detail. Moreover, the manufacturing of the watch is a combination of both old school manual methods and modern technology, reflecting a typically Japanese embrace of technology, not for cost efficiency, but for the sake of quality. Initial thoughts I first came across Nouvelle Chronometrie on Instagram. It was just images of the watch, with no information on the brand’s origins. Then I learnt Nouvelle Chronometrie was founded and led by Noritaka Sakurai, a longtime collector who pivoted to join the industry – which ironically left me a little sceptical. Though I have known Mr Sakurai for a long time and regard him highly as a collector, he was chief executive at Hajime Asaoka’s watchmaking outfit until 2020 – that employer was a red flag for me. Fortunately, Mr Sakurai has left that behind, and has now gone all in with Nouvelle Chronometrie, a project that deserves recognition and praise. Accor...

Ferdinand Berthoud, Inverted: The Chronomètre FB 2TV.1

Ferdinand Berthoud (FB), Chopard’s haut de gamme sub-brand, introduces its first flying tourbillon just weeks before Watches & Wonders. The Mesure du Temps 1787 Chronomètre FB 2TV.1 is exceptional in both quality and price, presenting almost everything of interest on the dial side - chain and fusee included - along with hacking and zero-reset seconds. The dial-side spectacle will be the calling card of the new Mesure du Temps 1787 collection. Initial thoughts The revival of long-dead masters’ names to sell unrelated watches is a practice that invites scepticism - and often deserves it. The Ferdinand Berthoud brand, however, is a different matter. There is nothing cynical about it, and one suspects the man himself wouldn’t mind being associated with some of the finest mechanical watches being made today - in his home town, no less. A different name on the dial, Scheufele perhaps, might still feel more authentic, but that’s a minor quibble with what is otherwise an overwhelmingly high quality watch. The latest take on the brand’s chronometer-inspired formula adds one of my favourite features: a zero-reset seconds hand. Though I prefer the designs of the brand’s past projects, the FB 2TV.1 suggests the team at FB understands what the market wants, and the movement-as-a-dial aesthetic is hot right now. The flying tourbillon is new for the brand, in both technique and aesthetics. Until now the brand’s massive revolving regulators were secreted away on the...

Hands On: Ferdinand Berthoud Chronomètre FB 1 “Oeuvre d’Or”

Backed by Chopard and taking the name of a noted 18th century French watchmaker, Ferdinand Berthoud made its debut in 2015 with the Chronomètre FB 1. Though unusual in style with an octagonal case, the FB 1 boasts an impressively constructed movement developed and manufactured by the same facility responsible for Chopard’s top-of-the-line L.U.C calibres; the project was the brainchild of Chopard co-president Karl-Friedrich Scheufele. At its core the FB 1 is an elaborate – and delightfully anachronistic – tribute to 18th century marine chronometers inside and out. The subject of four patents, the unusual calibre is very much antiquarian horology; it is constructed with pillar-style architecture and contains a chain-and-fusée, feeler-and-cone power reserve mechanism, and a large tourbillon with central seconds. Since the debut of the FB 1, there have been as many as ten subsequent variations – which is probably too many but it doesn’t diminish from the intrinsic, technical qualities of the watch – with one of the most recent being the Chronomètre FB 1 “Oeuvre d’Or” launched last year. Mechanically identical to the other iterations, the Oeuvre d’Or is distinguished by extra decoration, namely an engraved and grained gold dial as well as gold movement bridges engraved with a repeating pyramid motif.

Back To Basics: Chronometers - What Are They, And Why Should You Care?

In this installment of Back to Basics, we’ll dive into chronometers. What does this term mean, and why should it be relevant to you? If you are (relatively) new to the watch hobby, the word “chronometer” may be somewhat confusing. Technically, any object that measures (meter) time (chrono) is a chronometer, right? Then why do […] Visit Back To Basics: Chronometers - What Are They, And Why Should You Care? to read the full article.

How chronometers went from ships to wrists

As soon as John Harrison realised that a pocket watch could be made to be just as accurate as his 60cm-tall chronometer sea clocks, the road to wristwatch chronometry had begun. Most watch enthusiasts are familiar with how wristwatches became popular after WWI, thanks to the convenience of keeping your hands free while soldiering. It … ContinuedThe post How chronometers went from ships to wrists appeared first on Time+Tide Watches.
