Watches by movement: From Tudor to Doxa, 7 watches powered by the ETA 2824

The watch landscape has changed massively over the last 20 years with an increased trend towards in-house calibers. No longer is ETA the only outlet for brands to source movements with Sellita effectively cloning ETA ebauches and Japanese providers such as Seiko, Miyota, and Citizen filling the void for even more cost-effective solutions. That being … ContinuedThe post Watches by movement: From Tudor to Doxa, 7 watches powered by the ETA 2824 appeared first on Time+Tide Watches.

The Omega Speedmaster Professional Has Gone Two-Tone (Or, Bi-Color)

Is two-tone back? Is it on its way back? Has it returned and then left again? I feel like for as long as I’ve been involved in watches as a hobby, people have been saying all of the above regarding multiple metal watches. I think the most common shared perspective is that two-tone watches (that’s usually, but not always, watches made with both steel and gold) were a staple in the 1980s, fell out of favor, and have been threatening a comeback pretty consistently for the better part of a decade. But I think maybe two-tone is as back as it’s ever going to be, meaning just about every signature (“iconic,” if you must) watch collection has a two-tone example. This week, we add the Speedmaster to the list, with two new references featuring Moonshine (yellow) and Sedna (red) gold.  The new two-tone (or “Bi-Color” in Omega terms) Speedys are from the Professional line, meaning these are Moonwatches at their core, even though they have just a bit of bling. That means a manually wound 3861 caliber with METAS certification, and the classic 42mm Speedmaster case. These references see gold applied to the bezel, crown, pushers, center links of the bracelet, and throughout each dial. The Moonshine Gold reference has a silver dial with gold tone subdials, while the Sedna Gold version has a dial coated in Sedna PVD with black subdials. Of course the most immediate question at hand is which one do you prefer, aesthetically? For me, it’s the Sedna Gold reference every day of...

Seiko Introduces the Presage Classic Series, with Dials Inspired by Japanese Silk

In addition to the announcement of new dive watches in Seiko’s Prospex line last week, the Japanese brand also revealed a total of five new watches in their Presage line, representing an entirely new collection. The Presage lineup has existed since 2016, and has become Seiko’s home for creating watches with a more refined vibe than their pure sports offerings, frequently paying tribute to traditional Japanese craftsmanship. This can come in a variety of flavors, from craft cocktails to watches with dials made in old fashioned craft traditions. These new watches take Japanese silk as their inspiration, and feel tied to previous Presage collections in the way they zero in on a specific facet of Japanese culture.  The new watches are part of what Seiko is referring to as the Classic Series, and are divided between simple three-handers with a date window at 3:00 and two references featuring a 24 hour subdial and an aperture at 9:00 through which you can see the caliber inside. The dials evoke Japanese silk in different ways. The three-handers have a fine texture that Seiko says is inspired by the lustrous qualities of the material, while the open-heart references are meant to evoke raw silk through a radial pattern. As with any dial inspired by something outside the discipline of watchmaking (the natural world, a particular type of craft, etc.), your mileage may vary on how accurately the dial represents a given subject. What matters most, I think, is whether you find it ...

Breitling Unveils a New Capsule Collection of SuperOcean Divers Inspired by the Scottish Highlands

In 2020 Breitling presented their throwbackiest watch to date. Yes, I made up that word. From its distinct concave bezel to its form fitting mesh bracelet, the SuperOcean Heritage ‘57 very much looked the part, yet had a very contemporary sizing of 42mm. Since then, this watch has been offered in multiple color variants, which included a very impressive rainbow colorway that featured a black dial and multicolored hands and indices.  Being so wildly different from their other SuperOcean models, including the standard Heritage line, I do not believe it got the attention it deserved. Despite being 42mm, the Heritage ‘57 was only 9.9mm thick. Its profile was impressive, and the lug thickness matched the bracelet thickness perfectly. It must have been a joy to wear.  Breitling is now introducing four new versions of the Heritage ‘57 dubbed the Highlands Capsule Collection. These new pieces have been downsized to more traditional vintage proportions and many will be jumping for joy at the 38mm diameter and short 42mm lug to lug length, making this one truly unisex. Somehow, they have even managed to shrink the thickness down to only 9.35mm and maintain the 100m of water-resistance. Inspired by the Scottish Highlands, there are four land-and-sea inspired dial colors available: beige, green, mustard, and blue. They all feature stainless steel cases and scratch-resistant ceramic bezels rimmed in 18k red gold. Powering these watches will be the Breitling Caliber 10 (a modifi...

INTRODUCING: The new Yema Superman Bronze collection debuts two new in-house calibers, with fresh dials in a strong combination of steel and bronze

The Yema Superman is a strong vintage diver, with two selling points that should be a wake-up call for other brands, starting with an obvious and rather rhetorical question: When you go out to buy a pair of jeans with your slimmer and shorter mate (speaking for myself here), do you buy the exact same … ContinuedThe post INTRODUCING: The new Yema Superman Bronze collection debuts two new in-house calibers, with fresh dials in a strong combination of steel and bronze appeared first on Time+Tide Watches.

New: IWC Portugieser Novelties for 2020 with Editorial commentary

We love that the popular chronograph gets an upgrade to an in-house chronograph caliber. This is very important for IWC to stay competitive especially with Georges Kern's Breitling B01 chronograph caliber. At around the same price but with a stock movement, the older model Portugieser Chronograph would become a party joke without the much needed upgrade.

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 ...

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,...

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...
