The A. Lange & Söhne Lange 1 displaying eccentric time and seconds with an asymmetrically positioned large date window is one of the most immediately recognisable Lange models. It was among the first models the firm presented when relaunched in 1994 and immediately captivated the hearts and minds of the public. It is now one of the cornerstones of the brand. The present reference 101.027 was introduced in 1997, setting itself apart from its peers. A. Lange & Söhne exclusively produced a rich dark blue dial, giving the watch a striking and eye-catching appearance. While the series is not a limited edition, the Blue Series was produced in only low numbers, making it a rare and scarce variant of its kind. So popular was the design that in 2017, A. Lange & Söhne released the second generation of blue dials with the reference 191.028. Powering the present early example of the Lange 1 Blue Series is the manual wound calibre L 901.0 with a beautifully finished three-quarter plate design made with German silver that provides up to 72 hours of power reserve.
