Sunday Morning Showdown: Grand Seiko’s Hi-Beat 9SA5 Vs. Spring Drive U.F.A. 9RB2

Good morning, everyone, and welcome to another Sunday Morning Showdown. I don’t know if it’s due to the heatwave we’re experiencing here in Europe, but this week, we’re doing things a little differently. On the other hand, it might simply be that Grand Seiko launched new Evolution 9 models that left us rather impressed. However, […] Visit Sunday Morning Showdown: Grand Seiko’s Hi-Beat 9SA5 Vs.

First Look - Zenith’s High-Beat Heart Exposed on the New Chronomaster Sport Skeleton

When Zenith unveiled the Chronomaster Sport in 2021, the message was clear: the El Primero was entering a new, sportier chapter rather than living off 1969 nostalgia. Exploiting the full potential of the calibre 3600’s 5Hz frequency, the 1/10th-of-a-second readings put the Chronomaster Sport luxury sports watch in a class of its own. The latest […]

What’s really new with these Grand Seiko Hi-Beat Divers?

It’s been just over four years since Grand Seiko gave us two divers using their venerated 9S85 Hi-Beat movement. Both titanium watches, the gold accented SBGH255 and the limited edition, blue dialled, SBGH257, were absolute beasts at 46.9mm wide and 17mm thick; something one might expect from a 600 metre professional diver. Since then, Grand … ContinuedThe post What’s really new with these Grand Seiko Hi-Beat Divers? appeared first on Time+Tide Watches.

Vacheron Constantin’s Twin Beat Returns with 70-Day Power Reserve SJX Watches

Vacheron Constantin’s Twin Beat Returns with 70-Day Power Reserve

First launched in 2019, the Vacheron Constantin Traditionelle Twin Beat Perpetual Calendar remains one of the most fascinating watches in its category. Thanks to a movement with a secondary, low-power mode, the Twin Beat has an extended power reserve measured in months – all contained in a reasonably sized, 41 mm case. The original version of the Twin Beat was complex and finicky. Now Vacheron Constantin (VC) has refined and upgraded the movement, resulting in a second generation model with an extra five days of power reserve in Standby mode – which means the watch will run for 70 days. Initial thoughts I described the original Twin Beat as a “genuinely interesting, albeit pricey, watch”. Even though several years have passed, the Twin Beat remains genuinely interesting. It is a novel concept executed in a sophisticated manner. In contrast to majority of ultra-long power reserve watches, the Twin Beat is ordinarily sized. I am certainly glad VC has revived the concept and made it better. The original probably had a few kinks in the movement that made production difficult so the first generation never really made it to market in significant numbers. The kinks have been resolved with the new version, which is probably also more robust from a usability point of view. The same holds true today of the price, though given the overall price index of the market, the new Twin Beat is arguably less expensive in relative terms. The first generation model Two running modes On ...

Editor’s note: Basel is just around the corner, which means that I’m spending more time than is strictly healthy speculating on what configurations of complications we might be seeing from our favourite brands … like Grand Seiko.

Grand Seiko is known for many things: mirror-like finishes, incredibly crisp casework and a design style that veers from conservative to downright quirky. But this is not a brand that springs to mind when you think of professional-grade dive watches. Until now.

Probably the most classic, emblematic and recognizable model made by Grand Seiko, the 44GS is the watch that created the “House Style” according to the so-called Grammar of Design.

Longines’ High-Frequency Chronometer Gets a Carbon Composite Case SJX Watches
Longines High-Frequency Chronometer Gets Jan 3, 2025

Longines’ High-Frequency Chronometer Gets a Carbon Composite Case

Arguably under appreciated, the original Ultra-Chron High-Beat Diver was a precision timekeeper with a high-frequency movement, the L.836.6. With the high-spec movement, the watch was appealing, albeit pricey by Longines’ standards. Now the brand has given the model an upgrade with the Ultra-Chron Carbon. The Ultra-Chron Carbon retains the familiar cushion-shaped case, but now in carbon composite, giving it lightness and a modern aesthetic that contrasts well with the retro, 1970s origins of the design. Initial thoughts The Ultra-Chron Carbon stands out for its blend of an advanced, industrial movement, composite materials technology (undoubtedly thanks to the Swatch Group’s vast industrial base), and a vintage-inspired aesthetic. Although it’s simply a modest variation of an existing model, the new Ultra-Chron marks the brand’s first venture into non-traditional case materials in the modern day. Priced at US$4,900, the Ultra-Chron Carbon commands a notably higher price than its stainless steel counterpart. While it does offer technical advantages - such as the carbon composite case and a high-frequency (5 Hz) movement - the watch still feels a little expensive relative to alternatives, especially since Longines is primarily a brand that competes in a lower price range. More broadly, the Ultra-Chron Carbon is not a like-for-like vintage remake, which is a good thing. But Longines can arguably do more with its movements. Given that the brand’s enthusiast-orien...

Up Close: Grand Seiko 60th Anniversary Hi-Beat SLGH003

Last year’s 60th anniversary was a major event for Grand Seiko, which unveiled several new movements and plenty of limited editions to mark the occasion. The most notable launch was probably the 9SA5 movement, a high-frequency and high-end automatic calibre. The movement made its debut in the luxe yellow-gold SLGH002, then in the steel Grand Seiko 60th Anniversary Hi-Beat SLGH003 a few months later. Since then the movement has been installed in a similar, but even more pricey platinum edition, and finally the regular production “White Birch” SLGH005. The cal. 9SA5 All the models are essentially the same, save for different dial finishes and case materials. Here we take a close look at the SLGH003 in steel as a representative for the “SLGH” family. Like its siblings in the family, the SLGH003 is a brand-new reference. The case and dial designs evolved from the existing and familiar Grand Seiko style, but inside is a radically new movement – the cal. 9SA5 with a Dual Impulse escapement. The aesthetic changes have created more refined exterior that better showcase the brand’s case finishing, but more crucially, the improvements signify the brand’s moves upmarket – exemplified by the more elaborate movement and higher price tag. The SLGH003 Initial thoughts Unique among the Grand Seiko line up in terms of its movement and styling, the “SLGH” family boasts new features that are mostly for the better, such as the more elaborate case and sophisticated mov...

Hands-On: The Vacheron Constantin 'Twin Beat' Perpetual Calendar Returns

When Vacheron Constantin announced the original Twin-Beat at SIHH in 2019, I wasn't in the watch space in the same way I am now. I was also focused on a much different price point—the one I shop in, not the one that I've since become fascinated by. So I missed it. A lot of people did, it seems. I don't think this watch, as interesting as it is/was as a first release, was made in particularly large numbers, and for over a year, I heard rumblings about the eventual return of the Twin-Beat. Well, it's here. It's improved. And yes, in the metal, it's both entertaining and impressive. But what is it? Essentially, the watch leverages two balances that beat at different rates to provide either 4 days of power reserve running at 5Hz or 70 days in standby mode at 1.2Hz. Oh, and it's a perpetual calendar as well. We covered the technical aspects back in 2019, so this will focus more on the watch as a revived model. The technical is the key here, but the form factor is impressive as well. A perpetual calendar, with dual balances, measuring 42mm and 12.3mm thick, it's hefty because of the platinum case, but it wears quite well despite the technicality. Vacheron has a tendency to make some impressively complicated watches and, unfortunately, make them quite large in the process. This would never have been a problem in the old days (especially for brands like Patek, which dominated this high-end, integrated complication space), but then again, the specifications of the old days don't ...

Introducing: The Vacheron Constantin Traditionelle Twin Beat Perpetual Calendar Is Back

What We Know Vacheron just brought back its incredibly unique Traditionelle Twin Beat Perpetual Calendar, and it's a welcome sight for dedicated collectors of the brand, along with general enthusiasts of unexpected yet innovative takes on complicated watchmaking. If you're not familiar with the original Traditionelle Twin Beat Perpetual Calendar, launched back in 2019, the watch offered an incredibly novel solution to a problem often found within perpetual calendar watches. Let's be honest, though the entire appeal and genius of the perpetual calendar is for someone wearing one watch all day, every day, for the whole year, watches like these are most often owned by those with a large collection to begin with. A weekend for a perpetual calendar in a watch box or drawer would mean that the complication would need to be set again after winding, and so Vacheron introduced this perpetual calendar with a whopping 65-day power reserve. To achieve this, rather than putting in an unfeasibly large mainspring in the barrel, the Traditionelle Twin Beat Perpetual Calendar lives up to its name by offering a new system that allows for switching between two beat rates for the watch—a contemporary high-beat 5Hz frequency with a 4-day power reserve for normal timekeeping during wear, but a much slower 1.2Hz mode with that prolonged power reserve for the "Standby" phase. The Caliber 3610QP comprises two separate gear trains for the two regulating systems, with a series of differentials tha...
