This A. Lange & Söhne reference 191.025 is the Lange 1 in platinum with the rhodié silver dial — the most understated form of the watch that relaunched the maison in 1994 and has defined it ever since. Everything the Lange 1 is known for is here: the off-centre, asymmetric dial laid out to the golden ratio, the small seconds and power-reserve indication, and the outsize date that has become the brand's signature. In platinum with a monochrome silver dial, the effect is quiet and almost stealthy, a look that has earned this version a devoted following among collectors. This generation carries the in-house hand-wound calibre L121.1, introduced in 2015, finished to Lange's exacting standard with a hand-engraved balance cock. The platinum case measures 38.5mm in height and width with a thickness of 9.8mm, compact yet weighty in the way platinum always is.
