A. Lange & Söhne caliber L141.1


With the 2020 manufacture calibre L141.1, all models of the LANGE 1 watch family that were originally based on the calibre L901 are now endowed with new movements. In comparison with the predecessor model, the 72-hour power reserve is achieved with only one spring barrel. Further technical details include a classic screw balance and a freely oscillating balance spring crafted in-house and calibrated for a frequency of 21,600 semi-oscillations per hour.

Lange-style quality hallmarks such as the three-quarter plate made of untreated German silver, screwed gold chatons, blued screws, an elaborate whiplash precision index adjuster as well as hand-engraved balance and intermediate-wheel cocks are visible through the sapphire-crystal caseback. The artisanal decoration of the movement, which is assembled twice, reflects A. Lange & Söhne's high standards in every detail.
