In Rose Gold, the Saxonia Thin 201.033 is the 37 mm version of the watch A. Lange & Söhne describes as its thinnest so far, a two-hand dress watch showing hours and minutes only. The Saxonia Thin first appeared in 2011 and was refreshed in 2016, and its restraint carries the idea behind the whole Saxonia family, which since 1994 has held Lange's most classical designs. It is the Rose Gold counterpart to the White Gold 201.027.

At 5.9 mm, the Rose Gold case sits flat on the wrist, and the Silver dial of solid silver carries only slender gold baton markers and two hands, with no seconds and no date. Through the sapphire caseback, the hand-wound movement shows the German silver plates and engraved balance cock of Lange's traditional finishing. An alligator strap closes with a Rose Gold prong buckle matched to the case.
