more....Although it is a pin lever movement, it is very well made with 17 jewels and a KIF shock protection.
more....In the past, especially between 1930 and 1980 more than 10.000 different movements were made, some in a million copies. The advent of the quartz watch in the 1970 terminated that impressive series, and the greatest part of those movements has not existed for a long time.
The movement archive on 17jewels.info, whose origins date back to the year 1997 (under a different name), should counteract further oblivion and show how diverse mechanical movements once were.
Of course it can never show the complete stock of all movements ever made, nevertheless, almost every week, new movements are archived and shown with detailed articles. Currently, more than 1337 different movements found their way into the archive and are at at least virtually accessible to posterity.
You can directly access the movement by the “movements” menu.
Besides the movements there are other pages, which complement the topic “mechanical watches”, such as a collection of Timex watches, some loose articles in the Magazine and Knowledge sections, a few datasheets and some other workbench related articles.
The archive lives from permanently acquiring yet unarchived movements, to catalogue and put them online. Who wants to support it with a small dontion, can get a “supporters” page as thanks.
Have fun exploring the world of mechanical movements!
