The Octava movement from Graizely & Co. (later Schild & Co.) was an 8-day power reserve pocket watch movement. It was originally developed by Frantisek Hartmann and Josef Oliàk of Prague and received patent CH33103 on March 11, 1905. This patent was purchased by Graizely & Co. of La Chaux-de-Fonds on April 13, 1907 and produced under the brand name Octava. The Octava was also covered by American patent 816321 and German patent 175275.

The Octava was Graizely’s second 8-day movement after the Hebdomas, which was invented and patented by Irénée Aubry in 1888. This movement was refined from the 1900s through the 1960s and remains in production to this day. Graizely & Co. produced both movements for some years in the 1910s and 1920s but eventually focused only on the more decorative Hebdomas.

The movement in patent US816321 is a mirror image of the Octava movement
