Nomos Glashutte Watch Orion Steel Back 301. Manufactory – one word that combines two Latin terms: manus = hand, factura = to make, to produce. In the watch industry, producers are designated as \"manufactories\" if they design their own movements and produce a significant part of the caliber themselves rather than buying these components from a third party. NOMOS is one of only a few watchmakers with the designation of manufactory. Movement: α (alpha)—manufactory caliber with manually wound movement. Steel case back.
