Spring started strong for Nivada. The Swiss watch brand released two new models in its Chronosport line, expanding it to five watches. We were lucky enough to try both the automatic and the mecaquartz versions. In this review, I’ll go hands-on with the former, namely, the Chronosport Blue. But before we get into that, let […] Visit Hands-On: The New Nivada Grenchen Chronosport Blue to read the full article.

It takes the skill of many craftsman to produce a complete Grand Seiko Spring Drive – and the dedication and talent of a single watchmaker.

2022: the Kodo constant force tourbillon. 2023: the Tentagraph hi-beat mechanical chronograph. 2024: the 9SA4 manual wound, hi-beat, dual-impulse escapement caliber, and Kodo Daybreak. It’s easy to forget that Grand Seiko has brought the proverbial heat to Watches & Wonders every year since the fair started, unveiling something that one could call “revolutionary” for the brand, if on varying scales. Well, it’s looking like 2025 will continue the trend with the introduction of Spring Drive Caliber 9RB2, the first caliber with U.F.A., or Ultra Fine Accuracy, designation. Before proceeding, there are two important concepts to understand: Spring Drive and Grand Seiko’s history with acronyms (which, if you know, feel free to jump two paragraphs ahead). Starting with the former, the elevator pitch, which I will take from our article dedicated to the topic is “Spring Drive combines the best of mechanical watchmaking and the best of quartz timekeeping to create a state-of-the-art caliber that lacks the weaknesses inherent to both of these movements.” A bit deeper, Spring Drive movements use the energy stored in a traditional mainspring to drive their proprietary “Tri-synchro” regulator, which replaces the classic lever escapement. It consists of a glide wheel, the rate of which is controlled by an electromagnetic brake, and is essentially regulated by an integrated circuit with a quartz oscillator. The result is a mechanical movement with quartz-like accuracy and...

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.

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 is the unofficial master of finding inspiration in natural phenomena. Many of the brand’s dials are crafted to resemble skies, waters, and landscapes found all over Japan-these two new USA-exclusive limited editions are no exception.

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...

Spring is here and a great time to get out and about, so I took the Bremont Martin-Baker II on a couple of outdoor adventures to see how this robust watch holds up in our latest Hands On Review! What We Love Comfortable on the wristBright, easy to read dialOrange colour pops & is fun What We Don’t Crown is hard to pull out and setWears on the larger sideStrap can be a little finicky to put on Overall Rating: 8.25/10 Value for money: 8/10Wearability: 9/10Design: 8/10Build quality: 8/10 For those that aren’t aware off the Martin-Baker story, here’s a quick re-cap. Martin-Baker is a British aviation company responsible for supplying 70% of the world’s Air Forces with fighter ejection seat technology. They first approached Bremont to create the definitive aviation watch in 2007. More than simply putting a logo on an existing model, the watch had to withstand the same rigorous testing programme as the ejection seats themselves. Two years later, the Bremont Martin-Baker I (MBI) was born and limited solely for pilots who have ejected from an aircraft using a Martin-Baker seat – something that is not all that fun and puts a tremendous amount of stress on the body and the watch! The MBI with red case ring – only for pilots who’ve survived a live ejection The MBII and MBIII were then produced for the general public, designed to the same strict standards of the MBI, but available in a range of colours and variants, with people able to choose their own colour for the mid...

Having launched several elegant and concise time-only watches this year, Grand Seiko has unveiled something once again simple but still unusual: the first regular-production, manual-wind Spring Drive 44GS, the Heritage Collection SBGY011 “Asaborake”. The SBGY011 combines two of the best elements of Grand Seiko (GS), namely the hybrid Spring Drive movement and the distinctive 44GS case. While the combination has been seen before, the SBGY011 brings something new to the table because the movement is manual wind, instead of self-winding as most Spring Drive calibres are. Initial thoughts I appreciate the SBGY011 because it retains the key features of the original, namely the 44GS case, silver dial, and hand-wind movement – but reinterpreted to incorporate contemporary elements such as the Spring Drive movement and patterned dial. Combined with the 44GS case, the silver dial gives the SBGY011 an aesthetic that’s close to the vintage 44GS of 1967. In fact, it’s essentially a modern, more technically-capable version of the original, which also contained a hand-wind mechanical movement. In fact, the SBGY011 is only the second hand-wind Spring Drive watch with a 44GS case, and the first and only one that’s not a limited edition. The hand-wind movement matters because the 44GS case is exponentially more attractive when it’s thin; in this case it is only 10.5 mm high. In comparison, a typical automatic Spring Drive is around 13 mm thick. Notably, despite being a regul...

Having first unveiled one set with diamonds and blue sapphires last year – that no doubt sold out briskly – Grand Seiko has just announced the Masterpiece Collection Spring Drive 8 Day Jewelry Watch 140th Anniversary (ref. SBGD207). This is similar to last year’s model – a Grand Seiko Spring Drive 8 Day with the dial, flange, and crown set with diamonds and garnets – combining the refined, artisanal movement finishing of the Micro Artist Studio with lavish gem-setting. Initial thoughts Last year’s sapphire-set 8 Day watch was impressive and truly special, being the first highly-jewelled, mechanical men’s watch from Seiko (or Grand Seiko) in two or three decades. The new SBGD207 in green is equally impressive, though it does reduce the unique nature of the original. Being a variant of the Spring Drive 8 Day, the SBGD207 will wear much like the standard model, which is extremely hefty and large for a Grand Seiko, and slightly top heavy on the wrist. The mass of the watch probably works better with the lavish gemstone setting, making the sparkle as over the top as the size. And because the SBGD207 has a green mother of pearl dial, it probably has more flash than last year’s model that had a grained, silvery dial finish. And the movement will be equally refined, having all the hand-finished intricacy of the 9R01 in the standard model. Though finely decorated, the movement lacks visual detail, because almost all of it is hidden under a single, massive barrel b...

Launched at Baselworld last year, the Seiko Prospex LX is a series of solidly-engineered sports watches conceived for air, land and sea – and designed in collaboration with Ken Okuyama, once the Creative Director at Pininfarina and one of Japan’s most prolific car designers. Powered by Seiko’s trademark Spring Drive movement, the Prospex LX Limited Edition SNR045 retains the familiar design modelled on the Seiko 1968 Hi-beat Diver, but now dressed in green. The textured dial is inspired by an underwater forest of moss pillars – nicknamed “kokebozu”, or “moss child”, by Japanese scientists – located at the bottom of a lake in Antarctica’s Skarvsnes Foreland. The “kokebozu” moss pillars in Antarctica Initial thoughts With both its dial and glossy ceramic bezel in forest green, the watch is immediately striking – and reminiscent of well-known, hulking green dive watch. The all-green dive watch is fashionable now, and Seiko is one amongst a host of brands doing it, so the colour is not unique. But Seiko executes its watches well – quality is excellent inside and out – and excels in highly-functional dive watches that perform well in legibility and usability. That sets this apart from the competition. As a sucker for textured dials, the ribbed dial pattern – meant to evoke the aquatic moss pillars – is highly appealing. It adds depth and character to what is otherwise a no-nonsense “tool” watch. I am not a fan of the power reserve in...

On its 60th anniversary, Grand Seiko goes modern with a new Spring Drive caliber, that takes its modern watchmaking to a new level.
SJX Watches
For its 60th anniversary, Grand Seiko has just unveiled one of the most extravagant, and expensive, watches ever – the Grand Seiko Masterpiece Collection Spring Drive 8 Days Jewelry Watch (ref. SBGD205). Combining the flagship Spring Drive model – made at the artisanal Micro Artist Studio – with a lavish setting of diamonds and sapphires, the Spring Drive 8 Days Jewelry Watch is a departure from the typical, subtle formality of Grand Seiko design. The base of the Spring Drive 8 Days Jewelry Watch is the SBGD201, an immense, heavy and refined wristwatch powered by the impressive 9R01 movement. Equipped with three barrels that give it a 192-hour power reserve, the 9R01 is finished to the same level as the much-vaunted Credor Eichi II, thought the massive full bridge means there are few details visible on the back. The dial of the watch is unusual. Though Grand Seiko (and Seiko) have always produced jewelled watches for women, this is probably the first heavily gem-set men’s model in a long time. The centre of the dial has a granular, slightly sparkly “dial dust” finish that is identical to the dial finish on the standard Grand Seiko 8 Days. But it has a subtle constellation of Leo – the Grand Seiko emblem is a lion – incorporated into the surface of the dial and visible only up close. Around the diamond-dust centre are two white gold chapter rings, one set with large, baguette-cut stones and the other with smaller, brilliant-cut stone. Each of the hours and ...
