Grand Seiko Steps Into The Future With New Spring Drive U.F.A. SLGB001 And SLGB003

Seiko founded Grand Seiko to pursue watchmaking excellence. Most commonly, this mission translated into creating the most accurate watches possible. Later on, aesthetics also played an increasingly important part thanks to the Grammar of Design. Grand Seiko was Seiko’s answer to the Swiss domination of the industry, and the line offered watches that could compete […] Visit Grand Seiko Steps Into The Future With New Spring Drive U.F.A.

Editorial – Who Invented the Balance Spring? Reaffirming the Crucial Role of Christiaan Huygens

An article by Rob Memel, antiquarian horologist, professional certified watchmaker since 1984, and author of the book The Development Towards Huygens’ Spiral Spring (1660-1676), from which this article is a summary. About two years ago, I embarked on an in-depth investigation into another watch-related invention by Christiaan Huygens: the spiral spring on a balance wheel. […]

The Greatest Horological Inventions of All Time: Why George Daniels’ Co-Axial Escapement Revolutionised Mechanical Watchmaking

Editor’s Note: Today, the final installment of The Greatest Horological Inventions of All Time. Here, Andrew Canter examines the story behind the co-axial escapement, invented by George Daniels, industrialized by Omega, and now considered one of the great watchmaking innovations of all time.  You can find more of Andrew’s work at the Mr. Watchmaster website here. George Daniels (1926 – 2011) was raised in London in poverty. Aged five, he pried open his family’s alarm clock and realised that it was a metaphor for his life – always moving inexorably onwards, but without outside assistance. He was determined to learn horology, despite his parents’ opposition. He was conscripted into military service in 1944 which unleashed his innate mechanical skills, and following the end of the war, he studied horology, while repairing watches in North London.  He gained access to the work of the greatest watchmakers, particularly Abraham-Louis Breguet, through a meeting with a collector, and when it seemed that quartz technology would overwhelm traditional watchmaking, Daniels ensured this would not come to fruition. He made a series of increasingly ingenious mechanical watches, heavily influenced by Breguet, teaching himself to make every part, now referred to as the ‘Daniels Method’. Essentially, he devised a virtually oil-free escapement – the now iconic co-axial escapement – which was later mass-produced by Omega. It was anything but an easy journey, but George D...

Hand Engraved and Unique, the MB&F; LM Split Escapement “Eddy Jaquet” SJX Watches

Hand Engraved and Unique, the MB&F; LM Split Escapement “Eddy Jaquet”

MB&F; is well known for its ability to consistently produce timepieces that are as much sculpture as technical marvels. In its latest collaboration, MB&F; leans heavily on the artisanal side of watchmaking, with a dose of literary influence. Executed by the namesake master engraver, the MB&F; Legacy Machine Split Escapement “Eddy Jaquet” is a limited series of eight unique pieces, each depicting a scene from famous novels, ranging from The Three Musketeers to Moby Dick. Initial thoughts The LM SE “Eddy Jaquet” is arguably a true, multifaceted work of art that just happens to be wearable. Mr Jaquet’s work is amongst the best, and the LM SE happens to be a perfect canvas for it thanks to the particular set up of the dial that leaves practically the entire dial disc free for engraving. Making such an ornate watch usually requires compromise in terms of time telling, with watchmakers often favouring an expansive decorated dial over prominent hands. The LM SE somehow manages to keep all of its sub-dials, along with the LM’s trademark exposed balance. These elements do not take away from the centrepiece, which is the engraved dial plate. The elaborate execution of the LM SE comes at a hefty price, CHF158,000, which is almost double the cost of a standard LM SE. A quiet master engraver While not a widely recognised name, Eddy Jaquet was actually one of the original “friends” of MB&F; since the brand’s early days. Back in 2011, he hand-engraved the names of Kari Vout...

The Greatest Horological Inventions of All Time: How The Invention of Balance Spring Changed the World

Editor’s Note: Today, we bring you the second part in the new series from Andrew Canter, the Greatest Horological Inventions of All Time. In this installment, Andrew examines the invention of the balance spring, a watchmaking advancement that not only charted a path for the watch industry, but can be said to have legitimately changed the world, enabling accurate, reliable, and portable timekeeping for the first time in human history. Who actually invented it, though, is still a matter of some debate, even after 350 years.  You can find more of Andrew’s work at the Mr. Watchmaster website here. Prior to the Balance Spring Early watches were powered by a verge escapement which was the same type of movement used in the early clocks. The verge is the earliest known type of mechanical escapement that controlled its rate by allowing the gear train to advance at regular intervals or ‘ticks’. Verge escapements were used from the late 13th century until the mid-19th century in clocks and pocket watches. Drawing of a verge escapement (bottom) and balance wheel (top) from an early pocket watch from an encyclopaedia c.1820 In the earliest watches a plain wheel, known as the balance, was used to control the rate of going of the mechanism. There wasn’t a consistent restoring force (such as a fusee), so consequently, its period of oscillation and, hence, the rate of the timekeeper were dependent on the driving force.

Grand Seiko Marks 20 Years of Spring Drive 9R

Grand Seiko’s debuted its first-ever Spring Drive movement in 2004 with the cal. 9R65. Now the brand is marking 20 years of the 9R Spring Drive movement family with the Elegance Collection SBGY035 and SBGA499, both sporting striking red dials inspired by the sunlit autumn scenery around Mount Hotaka. Part of the Thin Dress Series, the SBGY035 is flat and elegant, with a domed, textured dial. On the other hand, SBGA499 employs the classic Grand Seiko case and bracelet, matched with a sunburst-brushed dial in red that has the signature Spring Drive power reserve indicator at eight o’clock. The SBGA499 Initial thoughts I am a Grand Seiko fanboy. The brand offers a strong value proposition across its catalogue. Furthermore, Spring Drive is synonymous with Grand Seiko. The hybrid approach of Spring Drive means it boasts quartz-level accuracy despite being having an entirely mechanical mainspring and gear train. The new pair are perfect representations of Grand Seiko’s approach to horology, both good and bad. The two watches are striking, especially since red isn’t a colour often employed by Grand Seiko. The SBGY035 in particular stands out since the textured red dial is uncommon for Grand Seiko and dress watches in general. The SBGY035 That said, Grand Seiko’s limited editions feel too frequent, especially since many are only colour variations of each other. This is a regular criticism of Grand Seiko, but it hasn’t dampened sales of such limited editions, which pro...

Grand Seiko Celebrates a Big Spring Drive Anniversary with a Pair of Limited Editions

How long would it take you to invent an entirely new kind of watch movement? Five years? Ten years? If your answer was 27 years, you’d be on the right track. That’s how long it took the Spring Drive movement to go from idea to reality at Seiko. Initially conceived of by Yoshikazu Akahane in the 1970s, the development of the Spring Drive movement grew out of efforts to solve problems endemic to early quartz movements, though the project would not bear fruit until Baselworld 1999 when the first trio of Spring Drive watches was released to the public (something Akahane would, tragically, not live to see). Five years later, Spring Drive would finally reach Grand Seiko with the introduction of the 9R series of movements in 2004. 20 years later, the 9R series of Spring Drive calibers remain a core pillar of the Grand Seiko catalog, and GS is ready to celebrate that anniversary with the introduction of two profoundly autumnal limited editions. Each of these limited releases is powered by a Grand Seiko 9R series movement and each is inspired by the fiery red tones found throughout the Hotaka mountain range come fall. First up, we have the SBGY035, driven by a hand-wound Caliber 9R31 Spring Drive movement. Similar in execution and design to the popular SBGY007 Omiwatari, this thin dress watch claims inspiration from the vibrant leaves that coat the landscape of Hotaka each fall. An ombré finish made up of deep red tones is paired with a textured dial, and is accented by sparin...

Grand Seiko Unveils the Spring Drive GMT SBGE307 “Tokyo Lion” SJX Watches

Grand Seiko Unveils the Spring Drive GMT SBGE307 “Tokyo Lion”

Following last year’s SBGA481, Grand Seiko continues to expand the Sport Collection “Tokyo Lion” series inspired by the big cat in the Grand Seiko emblem. Like its predecessor, the Sport Spring Drive GMT SBGE307 “Tokyo Lion” sports a stylised, angular titanium case inspired by a lion’s paw and a textured dial modelled on a mane, now joined by a red GMT hand. Initial thoughts The “Tokyo Lion” is one of the most distinctive case designs in Grand Seiko’s large catalogue, and also the flagship given its complex finishing (and accompanying price). While most Grand Seiko watches opt for patterned dials and conservative, even bland, case styles, the “Tokyo Lion” makes a statement with its is generous dimensions and angular styling. The design is also particularly suited to Grand Seiko’s signature flat-polishing technique. With their wide, flat surfaces, the claw-inspired lugs are an excellent medium to showcase zaratsu polishing. It is, however, a large case at almost 45 mm wide and 15 mm high, so it’s catered to someone seeking a bold sports watch, and not an old-school Grand Seiko dress watch. The texture of the dial is striking, even though Grand Seiko has no shortage of dial patterns in its offerings. The dial artfully mimics a lion’s mane, giving it more visual depth than the typical Grand Seiko dial. Though few, the red accents on the dial add just enough colour and complement the ivory dial well. The dial might have been slightly dull without th...

Editorial: Geneva Auctions Spring 2024 Part II SJX Watches
Patek Philippe Grande Sonnerie ref 6301A May 17, 2024

Editorial: Geneva Auctions Spring 2024 Part II

The spring auction season in Geneva started dramatically enough with a cyberattack at Christie’s that took down its website and app. Only Watch went ahead as scheduled, however, and raised over CHF28.3 million, with most of that coming from the Patek Philippe Grande Sonnerie ref. 6301A that sold for CHF15.7 million. What transpired at Only Watch also played out in the subsequent auctions over the weekend. The live sales at the four auction houses, Antiquorum, Christie’s, Phillips, and Sotheby’s, sold almost CHF85 million of watches, including fees (excluding Only Watch). This compared to over well CHF110 million for Geneva’s fall season last year. Although the sale season six months ago was buoyed by an extra live auction at Christie’s (that was subject of much chatter), the diminished total for this season reflects the state of the market. The waning sentiment was palpable in all the salerooms. That said, the auctions did throw up a handful of grand surprises, including CHF3.13 million for the Patek Philippe ref. 605 HU world time pocket watch with cloisonné enamel dial at Antiquorum, and CHF1.16 million for the Rexhep Rexhepi Chronomètre Contemporain I at Phillips. Christie’s sold the most expensive wristwatch this season with CHF2.47 million for a Patek Philippe ref. 1518 “pink on pink” (above), though Antiquorum claimed the title for most valuable timepiece with its ref. 605 HU pocket watch.

Grand Seiko Celebrates 20 Years of 9R Spring Drive SJX Watches
Grand Seiko Celebrates 20 Years Feb 7, 2024

Grand Seiko Celebrates 20 Years of 9R Spring Drive

Grand Seiko is celebrating the 20th anniversary of 9R Spring Drive movement with a pair of limited editions featuring dials inspired by the sunrise at Mount Hotaka, a peak near the Grand Seiko workshop in Shiojiri. The first model is the Heritage Collection Caliber 9R 20th Anniversary “Pink Snowflake” (SBGA497) that revisits the first ever watch model with the 9R but with the trademark “snowflake” dial in pink. And the second is the Sports Collection Spring Drive GMT Caliber 9R 20th Anniversary (SBGE305) combining a black ceramic bezel with a dark red sunburst dial. Initial Thoughts The invention of the Spring Drive calibre is arguably one of Seiko’s most important achievements. It encompasses most of the advantages of mechanical movement while retaining the accuracy of quartz. Similar to a fully mechanical movement, it is powered by a spring rather than a battery, while timekeeping is regulated by a quartz crystal. As the first-ever commercially available Spring Drive variant, 9R marks an important feat for Grand Seiko. Nevertheless, despite the two new releases being celebratory models for the 20th anniversary of the 9R Spring Drive movement, they don’t seem to offer anything remarkable or unprecedented. Rather, the choice of a Hotaka mountain-inspired dial for both watches seems cliche, considering how pink and red colour dials have been relatively common in the brand’s catalogue. Plus, the inspiration behind Grand Seiko’s dial seems rather repetitive, a...

Arnold & Son True Beat Tourbillon Escapement Reviewed by Tim Mosso: The Best Tourbillon that You are Unlikely to have Heard Of

The Arnold & Son True Beat Tourbillon Escapement (TBTE) embodies two of the Swiss watch industry’s greatest talents: craftsmanship and AstroTurf. Beautifully built but tenuously tied to an historical dead guy, the True Beat is a triumph on substance. With essentially no history but outstanding modern credentials, this tourbillon proves that talent alone can yield a great watch.
