This simple pre-WW II german pin lever movement has got a diameter of 12 1/2 lignes and an unsual beat rate.

From the 1940s dates this early windup form movement from the german DuRoWe of Pforzheim.

The crown wheel on this unidentifiable 11 1/2 line cylinder movement from around 1900 is non-functional.

This tiny (6 3/4 lignes only) windup movement was very popular in the 1960s for tiny ladies' watches.

With a diameter of only 6 lignes (13.2mm), this is the smallest round ETA windup movement.
more....In the past, especially between 1930 and 1980 more than 10.000 different small 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 1379 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!
