I tried to comment as much as possible in the Openscad design, and used a lot of parameters, so read up a little on escapements, and play around with the file.
The values I used give a pretty standard 30-tooth/7.5 tooth gap escapement which would give sixty ticks per revolution and work well with a pendulum with a 2 second period.
This is more of a proof of concept / engineering doodle and I would not expect it to work as is... besides having to add the pendulum, this is an ideal Graham escapement and some drop and some lock would need to be added to both the entry and exit impulse faces. :-)
(EDIT: I designed a little test jig powered by a rubber band for this thing, here: thingiverse.com/thing:7801 )
