A. Lange & Söhne Grand Lange 1 Platinum 117.025DUB

The Grand Lange 1 is the larger Lange 1, with the movement scaled up in the same proportion as the case so that the dial keeps its layout: hours and minutes off-centre on the left, and the outsize date, power-reserve display and small seconds on the right, arranged so that no indication overlaps another. This version is 40.9 mm across and 8.8 mm thick.

The standard platinum 117.025 shares the case with a silver dial, and the white gold 117.028 (black dial) and pink gold 117.032 (silver dial) are the same watch in other metals. The 115-series Grand Lange 1 references, such as the pink gold 115.032, are larger at 41.9 mm and 11 mm thick.
