HANDS-ON: 6 decades on and still going strong - the Piaget Altiplano 60th anniversary

Though Piaget has made a lot of noise in the past 12 months with the sporty steel Polo S, the undeniable heart of the collection is the ultra-slim and ultra-sexy Altiplano. Born in 1957 and named for the flat South American high plains, the Altiplano and the legendary caliber 9P that powered it, have become … ContinuedThe post HANDS-ON: 6 decades on and still going strong – the Piaget Altiplano 60th anniversary appeared first on Time+Tide Watches.

Introducing: The Krayon Parhelion, A Maximalist Take On The Brand’s Anywhere Watch

What We Know Pretty much anything that independent watch brand Krayon produces feels like it rests solidly in the if-you-know-you-know realm of exquisitely engineered high-end complications. The brand's focused catalog contains variations on three main complications—the universal sunrise and sunset calculator that is the Everywhere, the watchmaker-adjustable sunrise and sunset-indicating caliber that is the Anywhere, and the most recently introduced weekday and weekend pointer date display in the Anyday. Sure, Krayon's recent Pac-Man collaboration in a limited run of Anywhere watches might feel like an odd one out, but most of the examples I've seen on the wrists of collectors have all flown well under the radar with tastefully measured executions. But if you've ever wondered what a Krayon would look like with a touch—scratch that, a lot—of bling, well, the new Parhelion might just do the trick. It's hard to mistake this new watch for anything else in the catalog thanks to the sheer number of baguette-cut sapphires set across the entire watch—159 of them, to be exact. To house this number of gemstones, the case is 42mm in diameter, made from an alloy of white gold with a high percentage of palladium for a very white hue to match the brightness of the stones. Thickness, given the complication, is impressive at 9.5mm. When I first saw a prototype of the Parhelion a few months ago, only the bezel was inlaid with sapphires, in a stunning gradient from white to blue. Bu...

Hands-On: The Ressence Type 11 Hodinkee
Ressence Type 11 Jun 19, 2026

Hands-On: The Ressence Type 11

At a glance, the Ressence Type 11, which launched earlier this year at Watches and Wonders, might feel like every other Ressence. That's kind of the point. Distinct as it is within the collection, the Type 11 keeps the brand's visual language intact while changing what's underneath it. The biggest change is under the hood—it's the first Ressence to feature the brand's own integrated caliber, replacing the usual combo of an ETA base with Ressence's Orbital Convex System on top. Before we get to more on that, let's take a look at the Type 11's exterior. The 41mm by 11mm case, in grade 5 titanium, continues the trend seen in many of Ressence's recent releases toward more compact cases and feels like an evolution of the Type 9, in a sense. A fully polished, almost tonneau-shaped case features a short 45mm lug-to-lug measurement, while the lack of downturning of the lugs means the case still maintains quite a bit of presence on the wrist. On the Type 11, the lack of a bezel means the dial and crystal extend to the edges of the 41mm diameter. It's this kind of seamless visual effect that has lent models like the Type 1 and the Type 3 a distinctively futuristic look, and here it works very well with these lugs. Water resistance is bumped up to 3 ATM (as opposed to the typically "splash resistant" rating of its non-dive watches). On the dial side, we get the satellite display that Ressence is best known for, showing the hours, running seconds, and a power reserve indicator withi...

Tudor Scales Down Black Bay Chrono with the “Bumblebee” SJX Watches
Tudor Scales Down Black Bay Jun 3, 2026

Tudor Scales Down Black Bay Chrono with the “Bumblebee”

Tudor’s sports chronograph offers one of the strongest values in its category, but it was never compact. In a surprising move, Tudor has managed to rework the model into the Black Bay Chrono 39 “Bumblebee”, which is just 39 mm in diameter and a bit over 13 mm high. The new dimensions make this substantially trimmer than its predecessor, yet the “Bumblebee” still employs the high-spec MT5813 movement. Initial thoughts The “Bumblebee” resolves one of the key criticisms of the Black Bay Chrono. Earlier iterations of the model were appealing in many ways, ranging from value to movement, but a little chunky. The latest model is almost ideal in terms of dimensions, an accomplishment made all the more impressive as the case still contains the MT5813 movement, which has excellent technical credentials but not slimness. With a price tag of CHF5,500, the “Bumblebee” continues to be an obvious value proposition. That said, the bright yellow dial might not be for everyone (personally I prefer the pink or blue prior models), but the new case size is spot on. Given past practice, however, additional dial colours are probably in the works, so this case size will likely be available in more colours eventually. Bright but not bigger The “Bumblebee” gets its name from the high contrast dial that’s a bright yellow matched with black registers. The dial markings, hands, and indices are also black, as is the aluminium bezel insert. While yellow is an unusual colour for...

Introducing: Oris Celebrates Its Birthday With The 2026 Hölstein Edition

What We Know Every year on June 1, Oris celebrates the founding of its brand by releasing watches named after its hometown. This time, they're doing so with 250 numbered pieces based on the brand's new Artelier watch. The new version features small seconds, a 120-hour power reserve, the Caliber 401 movement, and an interesting retro-futuristic style. The new Oris Hölstein Edition 2026 has a stainless steel case measuring 39.5mm by 11.1mm, a 45.5mm lug-to-lug, and 30m water resistance. The dial is light grey with a subtle fumé effect from its shape, with a brighter subsidiary seconds dial in a mirror finish and a small red seconds hand. That silver, domed dial and claw-style hour markers make the watch feel a bit like a throwback to the late 1960s, but with modern specifications. The hour and minute hands have Super-LumiNova. As a bonus, the movement (while not COSC-certified) has an accuracy of 3/+5 seconds per day and is highly anti-magnetic. It's also automatic winding. The caseback uses a special laser treatment that engraves the Oris Bear, features the words "Hölstein Edition 2026," and produces a mirror-like, iridescent rainbow finish. To steal the description from one of the greatest haircuts known to man, it's business in the front and party in the back. The watch retails for CHF 3,800. What We Think Oris has been doing these limited editions, as far as I can tell, since 2020, and each one has been anything but traditional. Obviously, the Oris bear often plays a ...

Tudor’s F1 Season Begins with Black Bay Chrono “Carbon 26” SJX Watches
Tudor s F1 Season Begins Apr 30, 2026

Tudor’s F1 Season Begins with Black Bay Chrono “Carbon 26”

Continuing with a practice that began last year, Tudor has announced a limited edition as this year’s Formula 1 season kicks off. As with last year’s edition, the Black Bay Chrono “Carbon 26” is modelled on the livery of the racing car of Visa Cash App Racing Bulls (VCARB). It’s otherwise identical to last year’s model, which means it is lightweight, well priced, and equipped with the high-spec MT5813 movement. Initial thoughts The Carbon 26 is essentially last year’s watch with a new dial, but I like the new yellow and white livery than last year’s white and blue. The colours are subjective, but the value proposition of the watch remains objectively excellent (though the price has risen largely due to the strength of the Swiss franc). The Carbon 26 is still competitively priced next to its rivals. As an aside, I hope Tudor will eventually incorporate more design elements from its historical motor racing chronographs, like the Monte Carlo, into its modern-day F1 editions like the Carbon 26. The Carbon 26 is clearly a Black Bay – the “snowflake” hands are a giveaway – but the Black Bay is a dive watch rather than one for the road. Carbon inside and out The Carbon 26 gets its name from the carbon fibre composite case and bezel, which have a patterned surface typical of the material. The type of composite employed here is more subtle appearance-wise compared to other composites used in watchmaking, so at a distance the case appears a flat black. Thoug...

Hands-On: The Patek Philippe 50th Anniversary Nautilus Collection, Reference 5810G and 5610G Hodinkee
Patek Philippe 50th Anniversary Nautilus Collection Apr 23, 2026

Hands-On: The Patek Philippe 50th Anniversary Nautilus Collection, Reference 5810G and 5610G

Here's the thing. The 50th Anniversary Nautilus Collection was going to sell no matter what caliber was used, what case material was chosen, or what format was given. This is just a reality of the strength of Patek Philippe in the world today, and how in-demand integrated bracelet watches are. And to be clear, the Nautilus, along with the Royal Oak, set the tone long ago and remains at the pinnacle of the category. Actually, one would say the Nautilus remains at the pinnacle of *watches* in general when it comes to simple demand. It's the one that the most powerful people I know lust after the most – and I'm not saying that's good or bad, but it really just is. And here's the thing: the 40th anniversary of the Nautilus was a bit of a let-down for me. Because the Nautilus really is *the watch* for so many of us, and indeed, I am a true fan and always have been, and indeed, always will be, no matter how many dinguses I see wearing them today. 3700G Circa 1980, 5711R Circa 2015, 5811G Circa 2024 – Yes, I like the Nautilus a lot. As many of you know, the very first Patek Philippe I ever purchased was a 3940G. The very second? A Nautilus reference 3700A (I paid $18,000 for it, in a group buy with Paul Boutros, who bought a 222 for even less 😵‍💫). Some years later, I bought a very rare 3700G (I sold it to a close friend and mentor when he sold his company because it was something he'd always dreamed of owning). In 2015, when Nautiluses were still sitting in cases,...

Happenings: Claude Greisler To Lecture At The Horological Society Of New York

Resonance is one of the most fascinating physical phenomena explored in watchmaking, where two oscillators influence each other and eventually synchronize. Since Christiaan Huygens' 17th‑century observations with pendulum clocks, watchmakers have sought to harness it in wristwatches. At the May 2026 lecture of the Horological Society of New York (HSNY), Armin Strom Co-Founder and Master Watchmaker Claude Greisler will share how the brand successfully achieved resonance in 2016 with the caliber ARF15. Central to this innovation is the patented resonance clutch, which links the two hairsprings, allowing them to synchronize quickly and continuously average out rate deviations. Join Greisler as he explores the journey from theory to mechanism and the creation of a modern resonance system. About Claude Greisler "A passion for 'transparent mechanics', both from an aesthetic perspective and to showcase how our watches actually work, has always guided my design sensibility. From a watchmaking perspective, I honor the many generations of Swiss-German watchmakers in my family with an uncompromising commitment to perfection in both movement quality and finishing." - Claude Greisler Born into a watchmaker family, Claude Greisler began his formal watchmaking education at a watchmaker school in Solothurn, Switzerland, followed by advanced programs at the Centre Interrégional de Formation des Montagnes (CIFOM) in Le Locle. He graduated in watch restoration and watch development, com...

Watches & Wonders: Oris’ 24-Year-Old Product Design Engineer Just Reworked a Classic - This is the Sleek New Artelier Complication

Oris first introduced its Artelier Complication in 1991 alongside the Caliber 581, which notably featured a moonphase module developed in-house by the brand. The release marked another significant moment for the maison in its commitment to manufacture movements following the quartz crisis. The model’s presence ultimately faded but received new life in 2017 with an updated design that featured a more modern, cleaner style with slimmer, tapered lugs, and a redesigned bezel. At Watches & Wonders, we get the next evolution of the Artelier Complication.  The newest incarnation gives us another redesign from the 2017 edition while keeping the focus on highlighting the romantic moonphase. This updated take on the Artelier Complication comes from 24-year-old Lena Huwiler, Oris’s new Product Design Engineer. Huwiler has been able to achieve the perfect balance between honoring the model’s place in the history of the brand and propelling it forward with a design that will resonate with her generation. An old soul at heart, Huwiler admits she does not just find inspiration online but still appreciates architecture, crafts, and interior design. She clearly brings the duality of these sensibilities into her design for the new Artelier Complication. Here, Huwiler has given an Oris classic a modern, urban profile and reworked the moonphase display designed by and for the next generation of watch collectors. The major update here is in the complication and how it is presented thank...

Watches & Wonders: TAG Heuer Reinvents (a part of) the Chronograph with the Monaco Evergraph

When I think of Heuer, or TAG, or TAG Heuer, for that matter, I think of chronographs. You probably do too. Carreras, Monacos, Autavias, Monzas, Veronas, Montreals, etc… All iconic models, their pursuit of the stop-watch-in-a-wrist-watch goes far beyond just that of aesthetics. Famously, in 1969, they were among the first three brands to introduce an automatic chronograph with the Caliber 11. Then, in the 2010s, they pushed chronograph innovation to its limits with high-concept, high-frequency calibers like the Mikrograph, Mikrotimer, and Mikrogirder. In the last few years, TAG has focused more on the commercial side, honing in on a contemporary design language with the glass box Carreras, as well as a workhorse caliber of their own, the 80-hour, column-wheel, automatic TH20. 2026, however, marks a return to more innovative, if high-end times. Earlier this year, they introduced the six-figure Carrera Split-Seconds Chronograph, a 36,000bph rattrapante made in collaboration with Vaucher, under the category of “avant-garde horlogerie.” A curious development that was perhaps undermined by having such a daunting price, it did serve as an amuse-bouche to their big Watches & Wonders novelty: the Monaco Evergraph, which includes at least one first in watchmaking. There is a lot to unpack with the Evergraph, but the movement is a good place to start. Inside is a new caliber called the TH80-00. An integrated chronometer-certified automatic chronograph with 47-jewels, it featur...

Watches & Wonders: Grand Seiko Introduces the SBGY043 “Iwao Blue” Worn & Wound

Watches & Wonders: Grand Seiko Introduces the SBGY043 “Iwao Blue”

At Watches & Wonders 2026, Grand Seiko’s newest addition to the Elegance Collection brings together the things it does best. Namely, intricately textured dials with a nod to Japanese artistry, and its flagship Caliber 9R Spring Drive.  Engraved to resemble a weathered rock face, the SBGY043’s striking dial suggests the appearance of a mountain at dusk: Grand Seiko calls this pattern iwao, which translates to rock or crag. Depending on the angle it’s viewed from behind its domed sapphire crystal, different facets take on intermingling light and dark tones of blue, purple, and black. Its color is inspired by the tradition of katsuiro dyeing, a centuries-old technique and reportedly a favorite among the samurai class, which produces a deep indigo hue. Set against bright silver markers and hands - no blued seconds hand here, which is almost its own Grand Seiko tradition - it makes for an especially understated contrast.  This Iwao Blue version runs on the Caliber 9R31, a manual-wind Spring Drive movement with a 72-hour power reserve and visible through a clear caseback. The case is among the slimmest in the Elegance Collection, with standard zaratsu polishing and soft, rounded lugs. A nine-row stainless steel bracelet is the only option, which reflects the craggy-faced dial’s aura of ruggedness.  Grand Seiko enthusiasts, of which there are many, might remember this dial from 2021 - albeit in a sharp-angled Heritage case and with a Caliber 9R65 Spring Drive mov...
