Orion 38 / Open Case Back

The NOMOS Orion 38 384 places the hand-wound Orion design in a larger 38mm stainless steel case with a domed sapphire crystal back. It retains the collection’s white silver-plated dial, gold-coloured hour markers, tempered blue hands, and small seconds display, while giving the dial more open space than the 35mm Orion references. The case measures 38mm in diameter, 7.9mm in height, and 48mm from lug to lug. It has a domed sapphire crystal front and a domed sapphire crystal 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 uses fine gold-coloured hour markers. The tempered blue steel hands contrast with the pale dial surface, while the small seconds display at 6 o’clock follows the standard hand-wound Orion layout. The display consists of central hours and minutes with subsidiary seconds. Power currently comes from the NOMOS DUW 4001, a manually wound in-house calibre measuring 10 ½ lignes in diameter and 2.6mm in height. It has 17 jewels and a power reserve of up to 53 hours. Earlier examples of this reference were fitted with the Alpha calibre. The watch is supplied on a black Horween Genuine Shell Cordovan strap with a 19mm lug width.
