A. Lange and Sohne 191.028 Lange 1 18K White Gold Blue Dial RARE

The A. Lange and Sohne Lange 1 reference 191.028, introduced in 2017 as part of the exclusive “Blue Series,” is a quietly exceptional variant of the modern dress watch icon. Encased in 18K white gold and measuring 38.5 mm in diameter with a refined 9.8 mm thickness, the watch presents a deep blue solid-silver dial that elevates the signature asymmetric Lange 1 layout. Powered by the in-house manual-wind Caliber L121.1, the movement offers a 72-hour power reserve and features a jumping outsize date, power reserve indicator, and subsidiary seconds — all executed with Lange’s hallmark Germanic precision. This reference was produced for only one year and is now discontinued, making it a rare gem for collectors who value both design restraint and technical excellence. The movement’s three-quarter plate, free-sprung balance, and double-barrel architecture underscore its horological pedigree. As a contemporary iteration of the Lange 1 lineage, this piece bridges the brand’s storied rebirth with modern refinement, offering both collector relevance and understated rarity. Excellent Condition with A. Lange and Sohne box and papers dated 2018.
