Notes :
About Time To Tell: Time To Tell has one of the largest private digitized databases on the history of Swiss watchmaking, with over 2.3 TB of data on more than 1,000 Swiss watch manufacturers. This database has been built up over a period of some thirty years, and continues to be fed with around 50 to 100 GB of data every year. The database is made up of old documents, mainly Swiss trade journals, dating from the late 19th to the late 20th century. Most of these documents are not available on the Internet.
Historical articles published on the time2tell.com website always cite the sources used.
Time To Tell is a private company, independent of any watch manufacturer.
