A brief history of GruenWristwatches.com
GruenWristwatches.com was launched in 2009 as a place for Gruen collectors and restorers to hang out and trade information. The site originally included a lively Gruen-only forum, the first Gruen only forum on the net that demonstrated that there are many Gruen fans. The purpose was a simplistic one, connect Gruen collectors. From there it organically grew into a friendly, helpful, and dedicated community of collectors, restorers, and researchers.
The forum was up for 4 years from 2009 to 2013. In 2013 the forum was closed. Since then hundreds of pages of research data has been made available here, for free.
