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 strength, 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\u003eThis makes this spring part of the category of modern \"white metal\" springs, which, unlike classic blue carbon steel, are stainless, virtually unbreakable, and retain their elasticity. Citizen marketed its original mainsprings – similar to Swiss manufacturers with \"Nivaflex\" – consciously 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 heyday 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 mainspring \"Citizen PHINOX\" (single piece from original box).
