Some watches whisper their worth; this one lets gravity do the talking. A. Lange & Söhne has unveiled a new Datograph Perpetual, reference 410.136E, and for the first time in years the Saxon flagship chronograph comes on a full platinum bracelet — five links across, alternating brushed and polished, descended from the architecture Lange developed for the Odysseus, and attached to a 41mm platinum case. The result is one of the densest objects in serious watchmaking, limited to fifty pieces worldwide.

The dial plays its own quiet game. Black, with silver registers and — a rarity for the maison — diamond hour markers, eleven stones totalling a restrained 0.13 carats, doubled at twelve. It is glamour at a Glashütte register: present, precise, and entirely unwilling to shout.

Beneath it beats the L952.1, among the most admired calibres of the modern era — a manually wound flyback chronograph joined to a perpetual calendar, running at a stately 18,000 beats per hour with a 36-hour reserve. Through the caseback it remains what it has always been: an argument, laid out in German silver and hand-engraved cocks, that movement finishing is an art form.

The price, in the Lange manner, is available on request — which is also a fair description of the watch itself. Available through the maison’s boutiques only, and for fifty wrists prepared for the weight of it.
