A. Lange & Söhne Datograph Perpetual Returns with Platinum Bracelet

A. Lange & Söhne has released a limited edition Datograph Perpetual in platinum, marking two decades since the model’s debut. The watch, announced on October 24, arrives in a run of 50 numbered pieces and pairs a new in-house platinum bracelet with a black dial set with baguette-cut diamond hour markers. This is the first time the Datograph Perpetual appears with a bracelet since the early Wellendorff collaborations, and the first standard model to feature a black dial.

The platinum bracelet is a focal point of the release. Unlike the early Wellendorff-supplied versions, the new five-row bracelet is designed and produced by A. Lange & Söhne. Its links alternate between brushed and polished surfaces, with pronounced chamfers, and the deployant clasp is engraved with the Lange name. The bracelet doesn’t include micro-adjustment or tool-free features, and is built to fit closely with the case. According to A. Lange & Söhne, the bracelet is intended as a piece of jewelry, not a sports accessory, and is built entirely in 950 platinum.

The dial is another departure from previous editions. Eleven baguette-cut diamonds, totaling approximately 0.13 carats, serve as hour markers, with two short diamonds at three and nine o’clock to avoid obstructing the subdials, and a pair at twelve. The black dial, crafted from solid silver, is framed by a tachymeter scale and keeps the familiar Datograph Perpetual arrangement: an outsize date at twelve, twin subdials below for chronograph and calendar functions, and a moonphase at six. The subdials house further indications, including day/night and leap year pointers nested within the chronograph and calendar counters.

The watch’s case measures 41mm in diameter and 13.5mm in thickness, matching earlier platinum Datograph Perpetual references. Inside is the manually wound L952.1 caliber, unchanged from previous iterations. The movement combines a flyback chronograph with an instantaneous perpetual calendar and moonphase, and is constructed from 556 components. Its power reserve remains at 36 hours. The finishing, visible through the sapphire case back, includes untreated German silver bridges, Glashütte ribbing, and a hand-engraved balance cock.

Setting the calendar is made easier by a pusher at ten o’clock, which advances all indications by one day when the crown is pulled out. Recessed pushers on the case allow for separate adjustment of each calendar function. The rapid-correction pusher is disabled during the “danger zone” around midnight to prevent accidental damage, a detail that reflects the brand’s focus on technical safeguards.

The return of the platinum bracelet draws on the history of the brand’s rare metal bands for collectors. Wellendorff bracelets, once an ultra-rare option for Lange watches, have become highly sought after on the secondary market. The new bracelet, while distinct in design, recalls the exclusivity of those early pieces.

The Datograph Perpetual in platinum with bracelet is available exclusively through A. Lange & Söhne boutiques. Pricing is on request, but sources place it around EUR 250,000 to 280,000. Each watch is individually numbered on the case back.
