The Orion 33 (ref. 309) is the Tangente's quieter sibling, 32.8mm steel, pencil indices in place of painted Arabic numerals, blued straight hands, the same Alpha hand-wind caliber underneath. It is the Nomos most often recommended when the Tangente reads too graphic for the wearer and the smallest dress-watch reference in the brand's modern catalog.
The Orion launched in 1992 alongside the Tangente, both designed by Susanne Günther, as the brand's two foundational dress-watch references. The Orion's applied-index dial is the more-formal of the two and traces more directly to mid-century Saxon dress-watch templates than the Bauhaus-derived Tangente. The 33mm reference is the family's traditional size; the Orion 38 and Orion Neomatik 38 extend the line into modern proportions.
Limited 'Ladies' and 'Anthrazit' dial variants have run periodically.
Common things to check: papers (an Orion at this price tier is fine without papers but the Nomos card adds modest value); dial originality (the applied indices and the painted minute track do not refinish, verify printing under loupe); caliber Alpha (verify the Glashütte striping and the blued screws through the case-back); case finishing (the polished case is small enough that polishing wear is visible, verify lug crispness); strap (factory Nomos with branded buckle is the standard); sizing (the 32.8mm case is at the small end of modern wearable proportions, verify the wearer's wrist size expectations before purchase).
