Orion 33 Duo / Closed Case Back

The NOMOS Orion 33 Duo 319 is a compact two-hand Orion with a 32.8mm stainless steel case, a white silver-plated dial, and gold-coloured hands. It removes the small seconds display found on standard Orion models, giving the reference a more reduced dial layout within the smaller Orion case format. The case measures 32.8mm in diameter, 7.6mm in height, and 42.3mm from lug to lug. It has a domed sapphire crystal front and a closed stainless steel case back. The Orion case is defined by its rounded, lenticular profile, curved crystal, and tapered lugs. Current specifications list water resistance at 5 atm, an increase from the earlier 3 atm rating. The galvanized white silver-plated dial is free of numerals and subsidiary displays. Fine applied hour markers define the time scale, while the gold-coloured hands provide the only central display elements. The watch indicates hours and minutes only. Power currently comes from the NOMOS DUW 4001 Duo, a manually wound in-house calibre based on the DUW 4001 and adapted for smaller two-hand models. It measures 10 ½ lignes in diameter and 2.6mm in height, with 17 jewels and a power reserve of up to 53 hours. Earlier examples of this reference were fitted with the Alpha.2 movement. The watch is supplied on a beige vegan velour remborde strap with a 17mm lug width.
