To mark 20 years of the Datograph Perpetual, A. Lange & Söhne has released ref. 410.136E with a black diamond dial and a full platinum bracelet. The 41mm, 13.5mm-thick 950 platinum case houses the hand-wound calibre L952.1, a flyback chronograph with perpetual calendar and outsize date, with 556 components and a 36-hour power reserve. It is limited to 50 pieces; the price is on request and expected to be well above €250,000.

Why it matters: The return of a full platinum bracelet, one of the brand's rarest offerings.
