This week for Watches and Wonders 2025, Armin Strom releases the new One Week Titanium Skeleton (TI25-OW.75). The Armin Strom One Week Titanium Skeleton is exactly that—a mechanical marvel that manages to be both technically impressive and incredibly wearable. With a fully skeletonized movement housed in a Grade 5 titanium case, this is Armin Strom pushing the boundaries of openworking while keeping things light, both in weight and design. The result? A timepiece that you’ll want on your wrist every single day of the week. This watch isn’t just ticking boxes — it’s “removing” them entirely.

Titanium Grade 5 is the perfect choice for this kind of watch. It’s strong, lightweight, and has that understated cool factor that makes it easy to wear in any setting. The case has a 41mm diameter with a thickness of 10.6mm and a lug-to-lug measurement of 44.35mm. Titanium also has a slightly darker hue compared to steel, which adds to the watch’s modern, industrial aesthetic. For a piece that showcases mechanical complexity, the case remains sleek, allowing the movement to take center stage. The integrated bracelet with butterfly clasp has small H-links, which completes the industrial look (plus added comfort!). The One Week specs are quite nice—I’d almost forget I was wearing it if it weren’t so mesmerizing.

Calling it a dial almost feels like an understatement. The One Week Titanium Skeleton embraces true skeletonization, revealing layer upon layer of mechanical artistry. Armin Strom has taken things further than ever with this release, removing even more material to highlight the movement’s depth and complexity. The small seconds dial is openworked, exposing the power reserve indicator and escapement wheel, creating an animated visual experience. Even the main plate and barrels have been skeletonized. The indexes and hands are filled with Super-LumiNova, which, on skeleton dials of this nature, I find helps tremendously in low-light conditions.

A seven-day power reserve is a rare thing in the world of mechanical watches, and Armin Strom’s hand-wound ARM21 caliber delivers exactly that. This isn’t just about longevity—it’s about precision and reliability over the long haul. It beats at 25,200 vibrations per hour, contains 35 jewels, and is made up of 194 components. The power reserve indicator takes inspiration from antique pocket watches, using a cone mechanism to track remaining energy. Flip the watch over, and the case back offers an unfiltered view of the entire mechanism, making it just as captivating from the reverse side. The hand-finishing throughout the movement reinforces Armin Strom’s commitment to haute horology, with chamfered edges, polished screws, and a level of detail that rewards close inspection.

The Armin Strom One Week Titanium Skeleton is more than a watch—it’s a statement of engineering and design. It takes the concept of skeletonization to new heights while keeping things practical and wearable. With its lightweight titanium case, integrated strap, and week-long power reserve, this is a timepiece that proves high horology doesn’t have to be delicate. The Armin Strom One Week Titanium Skeleton (TI25-OW.75) is available now and limited to just 100 pieces, priced at CHF 39,000. For more information, please visit the Armin Strom website.
