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...

Grand Seiko Introduces the SLGB005 “Violet Dawn”

Earlier this year at Watches & Wonders, Grand Seiko revealed the SLBG003, which turned out to be one of the most impressive watches of the whole show. Housing the new 9RB2 Spring Drive caliber, the UFA (Ultra-Fine Accuracy) movement is certified to an almost incomprehensible +/- 20 seconds per year, or roughly 3 seconds per month. That makes it, according to Grand Seiko, the most accurate movement powered by a mainspring. It’s a truly impressive horological achievement.  Of course, as soon as a brand like Grand Seiko introduces an entirely new platform like the UFA, enthusiasts are on pins and needles waiting to see what comes next. It’s not that we can’t appreciate what we have in front of us, but particularly with Grand Seiko, we know that variants are coming in the form of new dial options and case materials. If you had asked me in the Spring when we’d see the first derivation on the UFA line, I probably wouldn’t have expected to see a new watch so soon, but last week Grand Seiko dropped the Evolution 9 Spring Drive UFA SLGB005, nicknamed the “Violet Dawn” for its deep purple dial. It’s always interesting to see what new watches in a new sub-collection come to pass, not just for what it says about where the line is going, but perhaps where it’s not.  The SLGB005, like its predecessor, is what we’d probably call a small-medium size by today’s standards, measuring a conservative 37mm. Unlike the titanium SLBG003, however, this watch is clad in a st...

Seiko Introduces Prospex Alpinist GMT SPB493J Limited Edition

Seiko’s Alpinist collection is welcoming a new member this week with the release of a new GMT reference featuring a dial inspired by the hornbill, a tropical bird of Southeast Asia. The watch is a Land Alpinist using the brand’s 6R54 caliber, and while this is an existing configuration released back in 2023, there are a few unique details here worth noting - from dial textures and colors to the black bezel piece. This watch is not only a celebration of the majestic hornbill, but also an expansion of the Alpinist platform that goes beyond the existing framework, hopefully opening the door to more expressive variations moving ahead. The Alpinist GMT was released in 2023 in what felt like a very natural move for the collection. As part of the Prospex Land family, the new Alpinist references utilized a fixed, 24-hour steel bezel and an internally rotating compass bezel. Use of the 6R54 allowed the addition of a 24-hour hand into the mix; however this is the so-called “caller” style of GMT hand, meaning the hour hand cannot be set independently on the go. Still, it’s a welcome addition to the modern series carrying forth Seiko’s historic Alpinist name, and retains the charming design of the original. This newest reference to the collection is the SPB493J, and it mixes up the formula just enough to stand apart from the rest. This watch uses base blacks set against the steel 39.5mm case and bracelet, with the inclusion of a deep green color used for the rotating inn...
