A ref. 704.025 Lange 1 Tourbillon from the early, initial run of 150 examples in platinum. The 378-component L961.1 calibre was designed to not interrupt Lange 1 design principles while also nodding to traditional historic Glashütte pocket watch Tourbillons. Impressively, the Lange 1 Tourbillon is only .4mm thicker than the time-only variant while incorporating innumerable thoughtful design choices such as brilliant-cut diamond pivots for the tourbillon carriage, an aperture designed to conceal the date disc, and multiple bridges in floral-engraving motif. Finished, engraved, and designed thoughtfully, ref. 704.025 is the rare exception where complication has built on design rather than interrupting it.
