First Look – The New Grand Seiko Tokyo Lion Tentagraph SLGC009

NOMOS Adds a Worldtimer to the Club Sport Line Worn & Wound

NOMOS Adds a Worldtimer to the Club Sport Line

I love a worldtimer complication, if only because it allows me to envision a timeline in which I’m a spunky world traveler who isn’t afraid of losing my passport or getting lost in the desert. Something about seeing the names of all the places I haven’t been to (yet) on my watch is a surefire cheer-up when the world inside my apartment starts feeling a little small. Pair that global functionality with mature, elegant styling, and you have the new NOMOS Glashütte Club Sport neomatik Worldtimer. Measuring at a democratic 40mm with an equally accessible 20m lug width, the Worldtimer’s stainless steel case is kept slim and simple-so slim, in fact, that it claims to be one of the world’s thinnest worldtimer watches. NOMOS Glashütte’s proprietary caliber DUW 3202 neomatik movement is to thank for 4.8mm of the impressive 9.9mm total thickness of the watch and is still robust enough to offer the NOMOS swing system with DUW regulation and 100m of water resistance. And while all of this is remarkable in its own right, the German brand has more than impressive mechanical achievement up its sleeve with the Worldtimer.  Functionality is straightforward, and while the dial layout is a bit different from the enthusiast favorite Worldtimer NOMOS has been making for years, the pushbutton ease of cycling through world time zones will be familiar to anyone who has experienced one of those earlier watches. Just press the pusher at 2 o’clock until your current time zone is a...

The TAG Heuer Formula 1 Goes Solar Worn & Wound

The TAG Heuer Formula 1 Goes Solar

Much to the chagrin of my fellow automotive enthusiast friends, I am not an ardent Formula 1 follower-I prefer motorsports of the all-wheel drive variety, coated in mud in the Finnish wilderness. Still, the allure of the screaming engines, blinding speed, and pure bling of Formula 1 isn’t lost on me. Millions of fans worldwide are captivated by the sport and its entrants for a reason-and TAG Heuer, the official timekeeper of Formula 1, has nine new references to match that ever-growing fervor. In celebration of the colorful 1986 origin of the brand’s Formula 1 Collection, the new models feature bright hues and a reimagined design. Three of the nine pieces feature the more “classic” dial colors of black and white or blue on a steel bracelet. The remaining six are limited edition colorways: black and red, black and yellow, blue and black, white and green, white and red, and green and red.  According to TAG Heuer, each model pays direct homage to the 1986 collection in design and function. However, key changes reflect contemporary taste-instead of the original 35mm, the new cases (constructed of sandblasted steel or TH-Polylight depending on the model) measure 38mm but retain the sporty aesthetic that the line is known for. The original shield-shaped markers have also been modernized, appearing now as applied and Super-Luminova-treated indexes. The “Mercedes”-style hands carry on, as does the chunky 60-second scale bezel, date window at 3 o’clock, and agg...

[VIDEO] Grand Seiko Redefines Accuracy – Again: Introducing the 9RB2 U.F.A. Spring Drive Caliber Worn & Wound

[VIDEO] Grand Seiko Redefines Accuracy – Again: Introducing the 9RB2 U.F.A. Spring Drive Caliber

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...

TAG Heuer Refreshes the Carrera Day-Date and Adds a GMT Worn & Wound

TAG Heuer Refreshes the Carrera Day-Date and Adds a GMT

Reinventing the wheel can be overrated-sometimes, expanding on an already-beloved design is the best way to drum up excitement. The original Heuer Carrera-released in 1963 as Jack Heuer’s horological love letter to the 1950s Carrera Panamericana Road Race held in Mexico-would develop as a symbol of motorsports success over the following decades, frequently gifted to victorious drivers at huge events. As the current official timekeeper of Formula 1, the Swiss company is continuing that legacy of motorsports prowess with new watches in the Carrera Day-Date collection, keeping the elements that have made the watch an icon, while pushing the design ever forward.  With six new models and ample features, the Day-Date collection can seem as daunting as an F1 circuit at first. Five of the models, though, are mechanically identical, with differences ranging from materials to color schemes-these are the “regular” Day-Date pieces, while the Date Twin-Time represents a distinct complication. First, let’s take a look at the new Day-Date references.  Each Day-Date features a fine-brushed and polished steel 41mm case with a steel polished crown at 3 o’clock, a beveled and domed sapphire crystal with double anti-reflective treatment, and a steel screw-down case back that touts a 100m water resistance. A Calibre TH31-02 automatic movement pulses inside each Day-Date, and a day-date window sits at the 3:00 position. White Super-LumiNova additionally coats the hour and mi...

Zenith Reimagines Its Caliber 135 For The 21st Century

The year 2025 marks 160 years since the founding of Zenith in Le Locle, Switzerland, back in 1865. As watchmaking brands are wont to do, Zenith is commemorating this milestone by putting forward a watch for the occasion that’s representative of its storied history, as well as its own contemporary identity. Now, as Watches & Wonders 2025 kicks off, we are clear on how the brand aims to celebrate the occasion, and its chosen vehicle is a new collection inspired by Zenith’s own founder, complete with an update on its storied Caliber 135, which breathes fresh life into an old favorite movement. These are the conditions in which the rising star of the G.F.J. collection joins Zenith’s constellation. At the tail end of the 19th century, the mounting competition within the watch industry brought about a new standard of gauging the accuracy of movements, and watchmakers began employing observatory trials to signal to customers that their products were as accurate as possible. This was also at a time in which highly accurate timepieces were necessary for successful marine navigation. Before the COSC certification standards that are so rigidly defined today were coded, individual movements would be sent to observatories, where they would undergo testing procedures, as well as competitions for chronometry prices. Zenith details that it had been routinely entering chronometry trials as early as 1897. And, because a bit of healthy bragging is appropriate with brag-worthy achieveme...

Tudor Introduces the Black Bay 68, the Biggest Black Bay Yet Worn & Wound

Tudor Introduces the Black Bay 68, the Biggest Black Bay Yet

It’s a big year, literally and figuratively, for the Black Bay. This year, Tudor has introduced the all new Black Bay 68, continuing with a naming convention that began with the Black Bay 58 all those years ago. The new Black Bay 68 fills out the range of vintage inspired Black Bays with an all new size for the range, coming in at 43mm. According to Tudur, the new size was created to meet demand from customers who wanted a dive watch with a larger footprint. After the Black 58 and Black Bay 54 (both under 40mm) and the longstanding “standard” Black Bay coming in at 41mm, the Black Bay 68 represents genuinely new ground for the collection in terms of size, and signals that the small watch trend that many say started with the Black Bay 58 might be coming to an end.  If you’re familiar with the various forms of the Black Bay, there won’t be too many surprises here. The case is stainless steel with a unidirectional black bezel, with dial options in blue and silver. The dials are subtly domed and have a barely-there radially brushed finish, and are matched with large lume filled hour markers. The hands are the now familiar “Snowflake” style launched in 1969. While the case is 43mm, the important thing to note about these watches is that they are proportionally identical to the Black Bay 54 and Black Bay 58. So, in spite of the larger size, they wear in a way that feels quite familiar if you’ve spent any time at all with either of those earlier Black Bays. Accor...

TAG Heuer Introduces the Monaco Split-Seconds Chronograph in White Ceramic.

TAG Heuer’s flagship launch at Watches & Wonders 2025 is the Monaco Split-Seconds Chronograph F1, a tribute to the brand’s storied Formula 1 history. This striking timepiece features a white ceramic case that dispenses with a traditional metallic inner container in a departure from technical norms in construction. A red translucent dial reveal the mechanics below, while the chronograph counters - finished with an asphalt-like texture,white and yellow grid markings, and official F1 typography - proudly display British F1 commentator David Croft’s famous phrase: “Lights Out & Away We Go.” Initial thoughts At first glance, the Monaco Split-Seconds Chronograph F1 may appear to be just another Formula 1–inspired watch. However, a closer look reveals the subtle yet distinctive details that set it apart from its competitors. Rather than relying on overt F1 motifs, it integrates refined elements-such as the checkered-flag pattern-that showcase its superb craftsmanship and elevate it above other racing-inspired chronographs. Priced at CHF155,000, the Monaco may initially appear costly, particularly given TAG Heuer’s history of being more accessible. Yet, beyond the brand’s heritage lies a timepiece whose exceptional craftsmanship more than warrants its price tag. It is a Vaucher-powered rattrapante chronograph, and this version is unquestionably the most appealing of the iterations to date. And the Formula 1–inspired touches are thoughtfully integrated, an...
