H. Moser & Cie. is a trademark of Moser Schaffhausen AG, a Swiss luxury watch manufacturer. The original H. Moser & Cie. was founded by the independent Swiss watchmaker Heinrich Moser in St. Petersburg, Russia in 1828. Notable early clients of H. Moser & Cie. included Russian princes and members of the Russian Imperial Court; Vladimir Lenin also owned a Moser watch.

After Moser died in 1874, the company was split up between its Managing Directors. One of the Swiss parts in Le Locle went to the family of Paul Girard, the business in Russia was expropriated in 1918 due to the October Revolution. In 2002, Moser Schaffhausen AG was founded by Dr. Jürgen Lange together with Heinrich Moser’s great-grandson Roger Nicholas Balsiger, and the brand H. Moser & Cie. was formally re-launched in 2005.
