Introduced in 2017, A. Lange & Söhne launched the Blue Series with four emblematic models: Lange 1 Daymatic, Saxonia, Saxonia Automatic, and like the present example, Lange 1. Crafted from solid silver galvanically coated in rich deep blue and graced with solid-gold appliques and hour markers, the series was not a novelty from the brand but actually dates back to the first blue dial Lange 1 ref. 101.027 produced in the 1990s.

While the series is not a limited edition, the Blue Series is produced in only low numbers and as a one-off production, making it a rare and scarce variant of its kind. Powering the Lange 1 Blue Series is the second generation movement released in 2015, the caliber 121.1 with free-sprung balance wheel that provides up to 72 hours of power reserve.

Offering an eccentric ray of blue, the rare Lange 1 ref. 191.028 is preserved in excellent condition and charmed with its guarantee and accessories. Exceptional in design and craftsmanship, this is an opportunity for connoisseurs to snatch the reference made few.
