Zelos Swordfish 40mm Bronze Frost

Archive · used only

Zelos is a Singapore microbrand, and the Swordfish is its diver, here in a 40 mm case of CuSn8 bronze, 12 mm thick and 46 mm lug to lug, rated to 200 m. The Frost version has a full-lume white dial, filled with C3 X1 and BGW9 Super-LumiNova so the whole face glows, under a 120-click unidirectional bezel in bronze and a sapphire crystal with inner anti-reflective coating. It runs on the Seiko-made NH35 automatic, with a date wheel colour-matched to the dial. It came on a tropic rubber strap with a bronze buckle, at $349, and has since sold out.
