A. Lange & Söhne Zeitwerk Date

A. Lange & Söhne expands its contemporary digital timekeeping line with the release of the “Zeitwerk Date” (Ref#: 148.033) in a warm 18k pink gold case paired with a grey solid silver dial. This latest addition retains the collection’s signature jumping numerals and constant-force escapement, while offering a refined and elegant aesthetic through its monochromatic palette and precise German craftsmanship. Designed for collectors who appreciate mechanical ingenuity without sacrificing timeless design, this model continues the Zeitwerk tradition with a technically impressive peripheral date ring and exceptional hand-finishing visible through the sapphire crystal caseback.The case is crafted from 18k pink gold and measures 44.2mm in diameter with a thickness of 12.3mm. While its footprint is assertive, the short lugs and ergonomic curvature of the case allow for a more comfortable wrist presence. The bezel is polished to a mirror finish, while the case flanks feature a contrasting brushed surface that elevates the sense of refinement. A narrow step along the mid-case offers additional visual interest.Turning the watch over reveals a sapphire crystal caseback that provides a full view of the exquisitely decorated L043.8 movement within. The hand-finishing includes untreated German silver bridges, a hand-engraved balance cock, polished chamfers, and blued screws. Its architecture is signature A. Lange & Söhne, showcasing the brand’s Saxon watchmaking heritage at its highest level.Additional pushers are located at 4 and 8 o’clock: one for independently adjusting the hour display and the other for correcting the date. The case is topped by a sapphire crystal with anti-reflective coating on both sides, while the right side features a winding crown at 2 o’clock. Water-resistance can reach up to 30 meters (100 feet).
The dial is crafted from solid silver and finished in an elegant matte grey tone. Its layout is highly distinctive, centered around a symmetrical digital time display with jumping hours on the left and jumping minutes on the right. These windows are framed by the signature time bridge in untreated German silver, which visually integrates the central time display with the small seconds subdial at 6 o’clock and the power reserve indicator at 12 o’clock.Surrounding the dial is a peripheral date ring made of semi-transparent glass, on which numerals 1 through 31 are printed. Beneath this ring, a red marker highlights the current date by subtly appearing behind the corresponding numeral. This mechanism preserves the symmetry of the dial while offering an innovative solution to date indication. The power reserve and seconds hands are crafted from pink gold to match the case, adding warmth and visual cohesion.
All dial elements are finely executed with careful attention to balance and legibility. The contrast between the grey backdrop and white numerals ensures quick reading of the time, while the dial’s multi-layered design and recessed elements add depth and technical character. The domed sapphire crystal enhances the watch’s overall clarity and sophistication, completing the refined and contemporary aesthetic of this modern Saxon complication.
