Club Campus 38 Nacht / Open Case Back

The NOMOS Club Campus 38 Night 738 is the closed-back version of the 38.5mm Club Campus 38 with a ruthenium-plated dial, mixed Arabic and Roman numerals, and the DUW 4001 calibre. Earlier versions of this reference were powered by the Alpha movement. The stainless steel case measures 38.5mm in diameter and 8.5mm in height. It has a domed sapphire crystal front, a closed stainless steel back, and a screwed case construction. Water resistance is rated to 10 atm. The ruthenium-plated dial uses the Club Campus “California” layout, combining Arabic numerals with Roman numerals. The numerals and indexes are filled with beige Superluminova with blue luminescence, while the rhodium-plated hour and minute hands have white Superluminova inlays. A neon orange central seconds hand provides the main colour accent. Power 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. The watch is supplied on an anthracite vegan velour remborde strap with a 20mm lug width; earlier examples were fitted with a regular velour leather strap.
