What Makes It Special

Purple has been part of Armin Strom‘s DNA since the founder himself.

The Orbit Midnight Purple is not merely a dial colour applied to a known reference; it is the first time the brand has carried that colour through to the movement’s mainplate. The frosted, PVD-coated midnight purple plate sits beneath the fumé dial, which itself graduates from a vivid violet core to near-black at the periphery. Viewed through the sapphire crystal, front or back, the watch reads as a single chromatic statement rather than two separate surfaces.

The dial’s architecture reinforces this. Signature numerals at 12 and 6 o’clock are machined from solid Super-LumiNova® blocks rather than printed, and the applied hour markers carry the same luminescent fill. Hand-polished steel hands, made in-house, complete a composition that is coherent across every lighting condition, including the Gulf’s frequent interiors and evening settings.

Movement & Mechanics

The Calibre ASS20 does something no other movement had done before on a ceramic bezel: it puts the date there only when you ask for it.

Pressing the pusher at 10 o’clock animates a dedicated date hand, which travels to indicate the current date on the black ceramic bezel, then returns to 12 o’clock with a second press. The column-wheel mechanism controls the sequence with the same authority found in chronograph architecture, and the date advances automatically at midnight regardless of whether the hand is displayed. The result is a dial permanently free of a date window — clean geometry, no interrupted text track.

Energy delivery relies on Armin Strom’s patented Equal Force Barrel, which maintains consistent torque across the 72-hour power reserve. The automatic micro-rotor winds without disrupting the openworked aesthetic. At 3.5 Hz (25,200 vph), the 30-jewel calibre within 273 components is compact for a 43.4 mm case: the movement measures 35.52 mm × 8.42 mm, keeping the total case height to 12.6 mm.

Design & Heritage

Within the System 78 collection, each piece has been defined by a specific architectural tension — and here, it is the relationship between colour and transparency.

The caseback reveals hand-finished finger bridges with polished bevels, perlage, and circular graining across every surface. The purple mainplate creates a visual foundation that contrasts with rhodium-coated components rather than competing with them. The openworked construction is not decorative: Armin Strom’s founding philosophy, reinforced after the brand’s 2009 revitalisation under Master Watchmaker Claude Greisler and entrepreneur Serge Michel, is that movement mechanics should be legible from the dial side. That commitment is visible in earlier Biel-made pieces such as the Mirrored Force Resonance Ruby and the Dual Time GMT Resonance Aventurine, and it reaches a chromatic peak in this reference.

Ownership Considerations for the Gulf Collector

Twenty pieces is a constraint that concentrates both desirability and responsibility.

At CHF 36,000, the Orbit Midnight Purple occupies the upper tier of independent Swiss watchmaking without reaching the price floor of the grandes maisons. For a GCC collector, that positioning matters: the watch represents a genuinely low-production manufacture piece — assembled twice per Armin Strom’s quality protocol, fully in-house from Biel/Bienne — without requiring the waiting lists associated with brands of greater commercial scale. The integrated stainless steel bracelet with double-folding clasp ensures the reference is as wearable for a business dinner in DIFC as for a cooler winter evening on the Gulf coast.

The Tribute² Aurum demonstrated the brand’s capacity to sustain collector interest across successive limited releases. The Orbit Midnight Purple’s 20-piece ceiling and the novelty of the colour-matched mainplate give it a clear differentiating narrative within the System 78 family. For collectors who track independent watchmaking in the GCC market, it is one of the more precisely argued propositions of the 2026 calendar.
