Until the 1980s, this simple 10 1/2 pin lever movement from Germany was made in large quantities.
more....Tiny form movements with pin lever escapement, like this Brac 2051, are pretty unusual, especially, when they use a unique inhouse shock protection.
more....For decades, this simple pin lever movement powered simple ladies' and gents watches from Timex. It was available with and without center seconds indication.
more....For decades, this simple, tiny form movement powered several ladies' and even gents watches from Timex.
more....The maximum version of the Raeketa 2601.H caliber familiy with a day-date indication and a selfwinding mechanism.
more....Why?
This is probably the most often asked question by looking at this only 2.7mm flat russian windup movement.
One of only two cylinder movements, which Junghans produced, made in the 1930s.
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 1278 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!
