While most of Vacheron Constantin's horological creations remain circular, this model Historiques Rectangular ref. 91001/000G-8392 is reminiscent of wristwatches from the first half of the 20^th century; encased in 18k white gold, the model is sized at 26 x 40 mm x 7.9 mm and is from the 1990s. Furthermore, the white guilloche dial is accompanied by raised hour markers and a seconds sub-dial at 6 o’clock. The watch is powered by the slim hand-wound cal. 1017, based on the infamous JLC cal. 822, used for decades in the iconic Reverso.
