Armin Strom elevates the Orbit with bold Midnight Purple styling and its ingenious on-demand date complication.
Armin Strom is quietly becoming one of independent watchmaking’s most innovative manufacturers, and it is doing so not by simply creating increasingly complex timepieces, but by rethinking familiar ones. One quick look at the brand tells you almost everything you need to know. It has built its identity around skeletonisation, or what it calls “transparent mechanics,” exposing as much of the movement as possible to showcase the intricate complexity that lies beneath. Not only that, but it does so in a way that is highly eye-catching, with some of these dials resembling mechanical artworks for the wrist.
Armin Strom’s Orbit collection is a fine example of this. First introduced in 2022, the collection was not created around high complications such as a minute repeater, perpetual calendar or tourbillon. Instead, the brand chose to focus on one of watchmaking’s oldest complications: the date. The Maison redesigned how this complication should interact with the wearer and, in doing so, showed us that innovation does not always have to come through entirely new complications. Sometimes, it stems from completely rethinking how familiar ones should be presented.
The defining feature of the Orbit remains the world’s first on-demand pointer date displayed on the bezel. On traditional watch dials, the date occupies a fixed position and is shown through a date wheel that rotates beneath the dial. In this case, however, the date is marked around the bezel and is only displayed when the owner chooses to see it.
For this 2026 edition, Armin Strom is introducing the Orbit in “Midnight Purple.” While this may seem like a simple colour change on the surface, it is anything but. For the first time, Armin Strom extends its signature Midnight Purple beneath the dial itself, coating the movement’s mainplate in the same colour.
Case and Dial
The Orbit Midnight Purple is housed in a 43.4mm stainless steel case with a black DLC coating. This feels like a carefully considered design choice, as the black DLC creates a much stronger contrast against the purple than a stainless steel case would. While the diameter is certainly large compared to most modern sports watches, do not let the specification sheet fool you. The lug-to-lug measurement is just 44.35mm, which is extremely compact, especially considering the case size. With a thickness of only 12.6mm, this is a watch that should wear far better than the numbers might initially suggest.
One of the many highlights of this timepiece is the fixed black ceramic bezel, which also serves as the date display. The engraved numerals are finished in white for a crisp contrast, while the “Date” inscription appears in purple to match the watch’s overall colour theme. These details transform the bezel from a purely decorative element into an integral part of the complication.
The signature dial design of the Orbit, first introduced in 2022, remains unchanged here apart from the colour treatment. Alongside this Midnight Purple edition, the current Orbit collection also includes several other dial colours, including lime green, ice blue and black gold. Each dial features a fumé finish, which creates the collection’s distinctive gradient effect. On the Midnight Purple edition, the colour transitions from a vibrant purple centre towards darker outer edges, naturally drawing the eye inward.
This is not the only standout feature of the dial, however. The Orbit Midnight Purple also reveals Armin Strom’s commitment to transparent mechanics and hand-finishing. One of the coolest aspects of this watch is the way the movement is brought to the dial side. As a fan of skeletonised timepieces, seeing the micro-rotor at 12 o’clock and Armin Strom’s patented Equal Force Barrel, or Geneva stop-work mechanism, is certainly a treat, especially among all the surrounding hand-finished components.
There is also a first for this 2026 edition. While previous Orbit models concentrated their use of colour within the dial components, Armin Strom has now introduced a frosted Midnight Purple PVD-coated mainplate beneath the dial. This allows the movement itself to become part of the colour story, creating a far more visually captivating timepiece than its predecessors.
Movement
The Maison’s in-house Calibre ASS20 powers the Armin Strom Orbit, a movement that was specifically developed around the watch’s groundbreaking on-demand date complication. Armin Strom designed the movement to support this date complication from the get-go, all the while showcasing the intricate details of the movement on the dial in the brand’s signature design style.
The movement’s most remarkable feature, of course, is the world’s first column-wheel controlled on-demand pointer date. Activated via the pusher at 10 o’clock, the central date hand (with its midnight purple pointer) jumps from its neutral position at 12 o’clock to indicate the current date on the bezel before returning to its resting position with a second press.
Composed of 273 components, the ASS20 calibre operates at 3Hz (21,600 VpH) frequency, while delivering a power reserve of 72 hours. The ASS20 is also assembled twice during production, once to ensure perfect finishing and again for final assembly. This certainly is a labour-intensive process that only a handful of brands in the watchmaking industry undertake.
Initial Thoughts
Rather than reinventing the concept of the Orbit, Armin Strom has taken what is working well and evolved it through integrating new and vivid colours, allowing the mechanics of the watch to remain the star of the show. The Midnight Purple execution feels far more complete than the previous colours in the Orbit collection. Extending the colour into the movement transforms it from simply being a dial colour into a more ‘complete’ package.
The Orbit might feature one of the most original innovations in watchmaking over the last decade. While many watchmakers are continuing to produce elaborate versions of the perpetual calendar or tourbillons, this complication takes something as familiar as the date display and completely reimagines how it can interact with the wearer.
Limited to just 20 pieces, the Armin Strom Orbit is a great representation of what independent watchmaking does best. Rather than chasing trends, the brand has opted to reinvent a genuinely useful complication, all the while having exceptional finishing and a visually bold design.
