Both refer to the same high-quality \u003cstrong\u003ecobalt-chromium-nickel alloy\u003c\/strong\u003e (Co-Cr-Ni). This cobalt-chromium-nickel alloy offers a combination of high strength, ductility, and good mechanical properties, is hardenable, has excellent fatigue resistance, is corrosion-resistant, and non-magnetic. Phynox is also known under the names Elgiloy, Conichrome, and Alloy 3J21.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cspan class=\"inline-flex\" data-state=\"closed\"\u003e\u003c\/span\u003eThus, this mainspring belongs to the category of modern \"white metal\" mainsprings, which, in contrast to classic blue carbon steel, are rust-free and practically unbreakable, and retain their elasticity. Citizen deliberately marketed its original mainsprings – similar to Swiss manufacturers with \"Nivaflex\" – under the premium alloy name. It is therefore a \u003cstrong\u003eCitizen original part\u003c\/strong\u003e. The nostalgic box graphics also make the piece a decorative collector's item from the golden age of the Japanese watch industry.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eScope of delivery:\u003c\/strong\u003e\u003cbr\u003e1 piece \"Citizen PHINOX\" mainspring (single piece from original box).
