Lange \u0026 Söhne 1815 UP\/DOWN 234.021 Yellow Gold White Dial (2025)","description":"\u003cp\u003eNamed for 1815 — the birth year of Ferdinand Adolph Lange, founder of A. Lange \u0026amp; Söhne and pioneer of German watchmaking whose development of the Glashütte lever escapement transformed the Saxon town into Germany's watchmaking capital — the 1815 collection channels his nineteenth-century pocket-watch heritage through Arabic numerals, blued steel hands, and railway-style minute tracks. Reference 234.021 represents the current-generation 1815 Up\/Down in 18-karat yellow gold, introduced in 2013 as a comprehensively updated evolution of the original 221.021 that ran from 1997 to 2008. The \"Up\/Down\" designation refers to the \"AUF\/AB\" power reserve indicator drawn from traditional German pocket watch terminology, one of Lange's most distinctively characterful complications and a nod to the maison's Saxon horological roots.\u003c\/p\u003e\n\u003cp\u003eThe 39mm case in 18-karat yellow gold measures just 8.7mm thick and presents a solid silver argenté dial with black Arabic numerals, small seconds asymmetrically placed at four, power reserve indicator at eight marked AUF\/AB, a railway-style minute track, and blued steel hands. The hand-wound Caliber L051.2 — 245 components featuring the three-quarter plate in untreated German silver, screwed gold chatons, and hand-engraved balance cock that define Lange's finishing tradition — delivers a 72-hour power reserve visible through the sapphire caseback, completed by a hand-stitched crocodile leather strap with 18-karat yellow gold pin buckle.\u003c\/p\u003e","brand":"WATCH TRADING","offers":[{"title":"Default Title","offer_id":55101946265972,"sku":"P6716S","price":35000.0,"currency_code":"BRL","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/4186\/0212\/files\/a-lange-sohne-1815-up-down-234-021-yellow-gold-white-dial-2025-a-lange-sohne-1251228922.jpg?v=1786073279","url":"https:\/\/watchtrading.com.br\/products\/a-lange-sohne-1815-up-down-234-021-yellow-gold-white-dial-2025","provider":"WATCH TRADING","version":"1.0","type":"link"}
